MEMORY BUSES  
The Intel 440BX/GX AGPset supports the system and memory buses at both 66MHz and  
100MHz speeds. The 100MHz system and memory buses provide a higher bandwidth  
path for transferring data between main memory/chip set and the processor.  
DMA CHANNELS  
INTERRUPTS  
The SBC is fully PC compatible with seven DMA channels, each supporting type F  
transfers.  
The SBC is fully PC compatible with interrupt steering for PCI plug and play compati-  
bility.  
BIOS (FLASH)  
The BIOS is a Hi-Flex AMIBIOS with built-in advanced CMOS setup for system param-  
eters, peripheral management for configuring on-board peripherals, PCI-to-PCI bridge  
support and PCI interrupt steering. The BIOS chip is a boot block Flash device -  
28F002BX-T120. The BIOS may be upgraded from floppy disk by pressing <Ctrl> +  
<Home> immediately after reset or power-up with the floppy disk in drive A:. Custom  
BIOSs are available.  
CACHE MEMORY  
For Pentium III processors, the processor includes an integrated on-die, 256K 8-way set  
associative level two (L2) cache. The L2 cache implements the Advanced Transfer  
Cache architecture with a 256-bit wide bus. The processor also includes a 16K level one  
Chassis Plans

Specifications  
CBI/CGI Technical Reference  
(L1) instruction cache and 16K L1 data cache. These cache arrays run at the full speed  
of the processor core.  
For Celeron processors, a 128K unified, non-blocking second level (L2) cache improves  
performance by reducing the average memory access time and providing fast access to  
recently used instructions and data.  
DRAM MEMORY  
The DRAM interface consists of two dual in-line memory module (DIMM) sockets and  
supports auto detection of memory up to 512MB of Synchronous DRAM (SDRAM) for  
the 440BX or up to 1GB of SDRAM for the 440GX. Minimum memory size is 8MB.  
The System BIOS automatically detects memory type, size and speed.  
The SBC uses industry standard 64-bit or 72-bit wide gold finger DIMM SDRAM  
modules in two 168-pin DIMM sockets.  
______________________________________________________________________  
NOTE: Memory can be installed in one or both DIMM sockets. If only one DIMM  
module is used, it must be populated in the top DIMM socket (Bank 1 - BK1). If two  
modules are used, they must be the same DIMM type, but may be different sizes (see  
table below). EDO DIMMs are not supported. All DIMMs must have gold contacts.

MEMORY HOLE  
The SBC supports a 1MB memory hole option at 512KB-640KB or 15MB-16MB.  
ERROR CHECKING  
AND CORRECTION  
The memory interface supports ECC modes via BIOS setting for multiple-bit error  
detection and correction of all errors confined to a single nibble.  
PCI LOCAL BUS  
INTERFACE  
The SBC is fully compliant with the PCI Local Bus 2.1 Specification. It has optimized  
the PCI interface to allow the processor to sustain the highest possible bandwidth  
(greater than 100MB/sec sustained) and low latency of the PCI Bus. It supports PCI-to-  
PCI bridge technology, a pipelined snoop ahead feature and improved PCI to DRAM  
write-back policy. The PCI Local Bus interfaces to standard PCI option cards in the  
backplane, and to the on-board PCI Ultra Wide SCSI controller and PCI 10/100Base-T  
Ethernet controller. The PCI Local Bus interface to the backplane is compliant with the  
PCI Industrial Computer Manufacturers Group (PICMG) 1.0 Specification.  
UNIVERSAL SERIAL The SBC supports two USB 1.0 ports for serial transfers at 12 or 1.5Mbit/sec. The  
BUS (USB)  
Universal Serial Bus (USB) is an interface allowing for connectivity to many standard  
PC peripherals via an external port.  
CONCURRENT PCI  
Concurrent PCI maximizes system performance with simultaneous processor, PCI and  
AGP Bus activities. It includes multitransaction timing, enhanced write performance, a  
passive release mechanism and support for PCI 2.1 compliant delayed transactions.  
AGP VGA  
The 69000 HiQVideo video/graphic accelerator is an Accelerated Graphics Port (AGP)  
device. AGP is designed to off-load the PCI Bus by allowing graphics data to move  
directly from system memory. The 69000 integrates 2MB of high-speed SDRAM frame  
buffer memory into the chip.  
INTERFACE (NOT  
AVAILABLE ON  
BASIC MODELS)  
By embedding SDRAM and graphics controller logic on the same die, the 69000 delivers  
uncompromising performance. The increase in the frame buffer bandwidth enables the  
69000 to support high-color, high-resolution graphics modes and real-time video acceler-  
ation. The interface supports pixel resolutions up to 1600 x 1200 non-interlaced.  
Software drivers for enhanced performance and resolution are available for most popular  
operating systems.  
SYSTEM  
HARDWARE  
MONITOR  
The system hardware monitoring system monitors system voltages, temperature and fan  
speeds.  
The circuitry is based on National Semiconductor's LM80. The LM80 monitors seven  
system voltages, two fan speeds and the board ambient temperature. All of the voltages,  
fan speeds and temperature measurements have associated programmable watchdog  
limits. When any of these programmed limits are exceeded, the monitor software can be  
used to notify the SBC. In addition, the externally available OS# signal can be used to  
notify external hardware of any over-temperature condition.  
Fan speed monitoring can be configured to monitor two system fans.  
Chassis Plans

SERIAL INTERFACE  
Two high-speed FIFO (16C550) serial ports with independently programmable baud  
rates are supported. The IRQ for each serial port has BIOS selectable addressing.  
ENHANCED  
PARALLEL  
INTERFACE  
The SBC provides a PC/AT compatible bidirectional parallel port and supports enhanced  
parallel port (EPP) mode and extended capabilities port (ECP) mode. The ECP mode is  
IEEE 1284 compliant. The IRQ for the parallel port has BIOS selectable addressing.  
PS/2 MOUSE  
INTERFACE  
The SBC is compatible with a PS/2-type mouse. The mouse connection can be made by  
using either the PS/2 mouse header or the bracket mounted PS/2 mouse mini DIN  
connector. Mouse voltage is protected by a self-resetting fuse.  
KEYBOARD  
INTERFACE  
The SBC is compatible with an AT-type keyboard. The keyboard connection can be  
made by using either the keyboard header or the bracket mounted keyboard mini DIN  
connector. Keyboard voltage is protected by a self-resetting fuse.  
WATCHDOG TIMER  
The watchdog timer is a hardware timer which resets the SBC if the timer is not  
refreshed by software periodically. The timer is typically used to restart a system in  
which an application becomes hung on an external event. When the application is hung,  
it no longer refreshes the timer. The watchdog timer then times out and resets the SBC.  
The watchdog timer has two levels of enable. First, the watchdog timer jumper must be  
moved to the "enabled" position, which puts the watchdog timer under software control.  
The second level involves software control of the watchdog's timer retriggering. Bit 6 of  
the 82371EB GPOREG register at I/O address 437H must be set to a zero (0), which  
blocks the triggering clock to the watchdog timer circuit, thus scheduling a hardware  
reset in about 1.5 seconds.  
To refresh the watchdog timer, the software in the application toggles bit 6 of the  
GPOREG register. First the bit must be set to a one (1) to clear the watchdog timer  
delay; then it must be set to a zero (0), which schedules a system reset in 1.5 seconds.  
Toggling bit 6 of the GPOREG must occur within a period of less than 1.5 seconds to  
insure that a system reset is not issued.  
A set of watchdog timer software code and sample programs are available from  
Technical Support.  
POWER FAIL  
DETECTION  
A hardware reset is issued when on-board +5V voltage drops below 4.75 volts. In  
addition, if the 3.3V Monitor jumper (JU15) is enabled, a reset is issued if 3.3V is below  
tolerance. (See the Configuration Jumpers section later in this chapter.)

ISA BUS SIGNAL  
DESCRIPTIONS  
The following is a description of the ISA Bus signals. All signal lines are TTL-  
compatible.  
AEN (O)  
Address Enable (AEN) is used to degate the microprocessor and other devices from the I/O  
channel to allow DMA transfers to take place. When this line is active, the DMA controller has  
control of the address bus, the data-bus Read command lines (memory and I/O), and the Write  
command lines (memory and I/O).  
BALE (O) (Buffered)  
Address Latch Enable (BALE) is provided by the bus controller and is used on the system board  
to latch valid addresses and memory decodes from the microprocessor. It is available to the I/O  
channel as an indicator of a valid microprocessor or DMA address (when used with AEN).  
Microprocessor addresses SA[19::0] are latched with the falling edge of BALE. BALE is forced  
high during DMA cycles.  
BCLK (O)  
BCLK is the system clock. The clock has a 50% duty cycle. This signal should only be used for  
synchronization. It is not intended for uses requiring a fixed frequency.  
CHRDY (I)  
I/O Channel Ready (CHRDY) is pulled low (not ready) by a memory or I/O device to lengthen I/  
O or memory cycles. Any slow device using this line should drive it low immediately upon  
detecting its valid address and a Read or Write command. Machine cycles are extended by an  
integral number of clock cycles. This signal should be held low for no more than 2.5 micro-  
seconds.  
D[15::0] (I/O)  
Data signals D[15::0] provide bus bits 15 through 0 for the microprocessor, memory, and I/O  
devices. D15 is the most-significant bit and D0 is the least-significant bit. All 8-bit devices on  
the I/O channel should use D[7::0] for communications to the microprocessor. The 16-bit  
devices will use D[15::0]. To support 8-bit devices, the data on D[15::8] will be gated to D[7::0]  
during 8-bit transfers to these devices. 16-bit microprocessor transfers to 8-bit devices will be  
converted to two 8-bit transfers.  
DAK[7::5]#, DAK[3::0]# (O)  
DMA Acknowledge DAK[7::5]# and DAK[3::0]# are used to acknowledge DMA requests  
DRQ[7::5] and DRQ[3::0]. They are active low.  
DRQ[7::5], DRQ[3::0] (I)  
DMA Requests DRQ[7::5] and DRQ[3::0] are asynchronous channel requests used by  
peripheral devices and the I/O channel microprocessors to gain DMA service (or control of the  
system). They are prioritized, with DRQ0 having the highest priority and DRQ7 having the  
lowest. A request is generated by bringing a DRQ line to an active level. A DRQ line must be  
held high until the corresponding DMA Request Acknowledge (DAK) line goes active.  
DRQ[3::0] will perform 8-bit DMA transfers; DRQ[7::5] will perform 16-bit transfers.

ISA/PCI Reference  
CBI/CGI Technical Reference  
IO16# (I)  
I/O 16-bit Chip Select (IO16#) signals the system board that the present data transfer is a 16-bit,  
1 wait-state, I/O cycle. It is derived from an address decode. IO16# is active low and should be  
driven with an open collector or tri-state driver capable of sinking 20 mAmps.  
IOCHK# (I)  
I/O Channel Check (IOCHK#) provides the system board with parity (error) information about  
memory or devices on the I/O channel. When this signal is active, it indicates an uncorrectable  
system error.  
IORC# (I/O)  
I/O Read (IORC#) instructs an I/O device to drive its data onto the data bus. It may be driven by  
the system microprocessor or DMA controller, or by a microprocessor or DMA controller  
resident on the I/O channel. This signal is active low.  
IOWC# (I/O)  
I/O Write (IOWC#) instructs an I/O device to read the data on the data bus. It may be driven by  
any microprocessor or DMA controller in the system. This signal is active low.  
IRQ[15::14], IRQ[12::9], IRQ[7::3] (I)  
Interrupt Requests IRQ[15::14], IRQ[12::9] and IRQ[7::3] are used to signal the microprocessor  
that an I/O device needs attention. The interrupt requests are prioritized, with IRQ[15::14] and  
IRQ[12::9] having the highest priority (IRQ9 is the highest) and IRQ[7::3] having the lowest  
priority (IRQ7 is the lowest). An interrupt request is generated when an IRQ line is raised from  
low to high. The line must be held high until the microprocessor acknowledges the interrupt  
request (Interrupt Service routine).  
LA[23::17] (I/O)  
These signals (unlatched) are used to address memory and I/O devices within the system.  
They give the system up to 16MB of addressability. These signals are valid when BALE is high.  
LA[23::17] are not latched during microprocessor cycles and therefore do not stay valid for the  
whole cycle. Their purpose is to generate memory decodes for 1 wait-state memory cycles.  
These decodes should be latched by I/O adapters on the falling edge of BALE. These signals  
also may be driven by other microprocessors or DMA controllers that reside on the I/O channel.  
M16# (I)  
M16# Chip Select signals the system board if the present data transfer is a 1<N>wait-state, 16-  
bit, memory cycle. It must be derived from the decode of LA[23::17]. M16# should be driven  
with an open collector or tri-state driver capable of sinking 20 mAmps.  
Master16# (I)  
Master16# is used with a DRQ line to gain control of the system. A processor or DMA controller  
on the I/O channel may issue a DRQ to a DMA channel in cascade mode and receive a DAK#.  
Upon receiving the DAK#, an I/O microprocessor may pull Master16# low, which will allow it to  
control the system address, data, and control lines (a condition known as tri-state). After  
Master16# is low, the I/O microprocessor must wait one system clock period before driving the  
address and data lines, and two clock periods before issuing a Read or Write command. If this  
signal is held low for more than 15<N>microseconds, system memory may be lost because of a  
lack of refresh.

NOWS# (I)  
The No Wait State (NOWS#) signal tells the microprocessor that it can complete the present bus  
cycle without inserting any additional wait cycles. In order to run a memory cycle to a 16-bit  
device without wait cycles, NOWS# is derived from an address decode gated with a Read or  
Write command. In order to run a memory cycle to an 8-bit device with a minimum of two wait  
states, NOWS# should be driven active on system clock after the Read or Write command is  
active gated with the address decode for the device. Memory Read and Write commands to a  
8-bit device are active on the falling edge of the system clock. NOWS# is active low and should  
be driven with an open collector or tri-state driver capable of sinking 20 mAmps.  
OSC (O)  
Oscillator (OSC) is a high-speed clock with a 70-nanosecond period (14.31818 MHz). This  
signal is not synchronous with the system clock. It has a 50% duty cycle.  
REFRESH# (I/O)  
The REFRESH# signal is used to indicate a refresh cycle and can be driven by a micropro-  
cessor on the I/O channel.  
RESDRV (O)  
Reset Drive (RESDRV) is used to reset or initialize system logic at power-up time or during a  
low line-voltage outage. This signal is active high.  
SA[19::0] (I/O)  
Address bits SA[19::0] are used to address memory and I/O devices within the system. These  
twenty address lines, in addition to LA[23::17], allow access of up to 16MB of memory.  
SA[19::0] are gated on the system bus when BALE is high and are latched on the falling edge of  
BALE. These signals are generated by the microprocessor or DMA Controller. They also may  
be driven by other microprocessors or DMA controllers that reside on the I/O channel.  
SBHE# (I/O)  
System Bus High Enable (SBHE#) indicates a transfer of data on the upper byte of the data bus,  
D[15::8]. 16-bit devices use SBHE# to condition data bus buffers tied to D[15::8].  
SMRDC# (O), MRDC# (I/O)  
These signals instruct the memory devices to drive data onto the data bus. SMRDC# is active  
only when the memory decode is within the low 1MB of memory space. MRDC# is active on all  
memory read cycles. MRDC# may be driven by any microprocessor or DMA controller in the  
system. SMRDC is derived from MRDC# and the decode of the low 1MB of memory. When a  
microprocessor on the I/O channel wishes to drive MRDC#, it must have the address lines valid  
on the bus for one system clock period before driving MRDC# active. Both signals are active  
low.  
SMWTC# (O), MWTC# (I/O)  
These signals instruct the memory devices to store the data present on the data bus. SMWTC#  
is active only when the memory decode is within the low 1MB of the memory space. MWTC# is  
active on all memory write cycles. MWTC# may be driven by any microprocessor or DMA  
controller in the system. SMWTC# is derived from MWTC# and the decode of the low 1MB of  
memory. When a microprocessor on the I/O channel wishes to drive MWTC#, it must have the  
address lines valid on the bus for one system clock period before driving MWTC# active. Both  
signals are active low.

PCI LOCAL BUS  
OVERVIEW  
The PCI (Peripheral Component Interconnect) Local Bus is a high performance, 32-bit or  
64-bit bus with multiplexed address and data lines. It is intended for use as an inter-  
connect mechanism between highly integrated peripheral controller components,  
peripheral add-in boards and processor/memory systems.  
The "local bus" moves peripheral functions with high bandwidth requirements closer to  
the system’s processor bus and can produce substantial performance gains with graphical  
user interfaces (GUIs) and other high bandwidth functions (i.e., full motion video, SCSI,  
LANs, etc.).  
The PCI Local Bus accommodates future system requirements and is applicable across  
multiple platforms and architectures.  
The PCI component and add-in card interface is processor independent, enabling an  
efficient transition to future processor generations, by bridges or by direct integration,  
and use with multiple processor architectures. Processor independence allows the PCI  
Local Bus to be optimized for I/O functions, enables concurrent operation of the local  
bus with the processor/memory subsystem, and accommodates multiple high perfor-  
mance peripherals in addition to graphics. Movement to enhanced video and multimedia  
displays and other high bandwidth I/O will continue to increase local bus bandwidth  
requirements. A transparent 64-bit extension of the 32-bit data and address buses is  
defined, doubling the bus bandwidth and offering forward and backward compatibility of  
32-bit (132MB/s peak) and 64-bit (264MB/s peak) PCI Local Bus peripherals.

PCI LOCAL BUS  
SIGNAL  
The PCI Local Bus signals are described below and may be categorized into the  
following functional groups:  
DESCRIPTIONS  
System Pins  
Address and Data Pins  
Interface Control Pins  
Arbitration Pins (Bus Masters Only)  
Error Reporting Pins  
Interrupt Pins (Optional)  
Cache Support Pins (Optional)  
64-Bit Bus Extension Pins (Optional)  
JTAG/Boundary Scan Pins (Optional)  
A # symbol at the end of a signal name indicates that the active state occurs when the  
signal is at a low voltage. When the # symbol is absent, the signal is active at a high  
voltage.  
The following are descriptions of the PCI Local Bus signals.  
ACK64# (optional)  
Acknowledge 64-bit Transfer, when actively driven by the device that has positively decoded its  
address as the target of the current access, indicates the target is willing to transfer data using  
64bits. ACK64# has the same timing as DEVSEL#.  
AD[31::00]  
Address and Data are multiplexed on the same PCI pins. A bus transaction consists of an  
address phase followed by one or more data phases. During the address phase, AD[31::00]  
contain a physical address (32 bits). During data phases, AD[07::00] contain the least signif-  
icant byte (lsb) and AD[31::24] contain the most significant byte (msb).  
AD[63::32] (optional)  
Address and Data are multiplexed on the same pins and provide 32additional bits. During an  
address phase (when using the DAC command and when REQ64# is asserted), the upper  
32bits of a 64-bit address are transferred; otherwise, these bits are reserved but are stable and  
indeterminate. During a data phase, an additional 32bits of data are transferred when REQ64#  
and ACK64# are both asserted.  
C/BE[3::0]#  
Bus Command and Byte Enables are multiplexed on the same PCI pins. During the address  
phase of a transaction, these pins define the bus command; during the data phase they are  
used as byte enables. The byte enables are valid for the entire data phase and determine  
which byte lanes carry meaningful data. C/BE0# applies to byte0 (lsb) and C/BE3# applies to  
byte 3 (msb).  
2-14  
Chassis Plans  
 
CBI/CGI Technical Reference  
ISA/PCI Reference  
C/BE[7::4]# (optional)  
Bus Command and Byte Enables are multiplexed on the same pins. During an address phase  
(when using the DAC command and when REQ64# is asserted), the actual bus command is  
transferred on C/BE[7::4]#; otherwise, these bits are reserved and indeterminate. During a data  
phase, C/BE[7::4]# are byte enables indicating which byte lanes carry meaningful data when  
REQ64# and ACK64# are both asserted. C/BE4# applies to byte4 and C/BE7# applies to  
byte7.  
CLK  
Clock provides timing for all transactions on PCI and is an input to every PCI device.  
DEVSEL#  
Device Select, when actively driven, indicates that the driving device has decoded its address  
as the target of the current access. As an input, DEVSEL# indicates whether any device on the  
bus has been selected.  
FRAME#  
Cycle Frame is an interface control pin which is driven by the current master to indicate the  
beginning and duration of an access. When FRAME# is asserted, data transfers continue;  
when it is deasserted, the transaction is in the final data phase.  
GNT#  
Grant indicates to the agent that access to the bus has been granted. This is a point to point  
signal. Every master has its own GNT#.  
IDSEL  
Initialization Device Select is used as a chip select during configuration read and write transac-  
tions.  
INTA#, INTB#, INTC#, INTD# (optional)  
Interrupts on PCI are optional and defined as "level sensitive," asserted low (negative true),  
using open drain output drivers. PCI defines one interrupt for a single function and up to four  
interrupt lines for a multi-function device or connector.  
Interrupt A is used to request an interrupt. For a single function device, only INTA# may be  
used, while the other three interrupt lines have no meaning.  
Interrupt B, Interrupt C and Interrupt D are used to request additional interrupts and only have  
meaning on a multi-function device.  
IRDY#  
Initiator Ready indicates the initiating agent’s (bus master’s) ability to complete the current data  
phase of the transaction. IRDY# is used in conjunction with TRDY#. During a write, IRDY#  
indicates that valid data is present on AD[31::0]. During a read, it indicates that the master is  
prepared to accept data.  
LOCK#  
Lock indicates an operation that may require multiple transactions to complete. When LOCK#  
is asserted, non-exclusive transactions may proceed to an address that is not currently locked.  
Chassis Plans  
2-15  
 
ISA/PCI Reference  
CBI/CGI Technical Reference  
PAR  
Parity is even parity across AD[31::00] and C/BE[3::0]#. Parity generation is required by all PCI  
agents. The master drives PAR for address and write data phases; the target drives PAR for  
read data phases.  
PAR64 (optional)  
Parity Upper DWORD is the even parity bit that protects AD[63::32] and C/BE[7::4]#. The  
master drives PAR64 for address and write data phases; the target drives PAR64 for read data  
phases.  
PERR#  
Parity Error is for the reporting of data parity errors during all PCI transactions except a Special  
Cycle. There are no special conditions when a data parity error may be lost or when reporting  
of an error may be delayed.  
PRSNT1# and PRSNT2#  
PRSNT1# and PRSNT2# are related to the connector only, not to other PCI components. They  
are used for two purposes: indicating that a board is physically present in the slot and providing  
information about the total power requirements of the board.  
REQ#  
Request indicates to the arbiter that this agent desires use of the bus. This is a point to point  
signal. Every master has its own REQ#.  
REQ64# (optional)  
Request 64-bit Transfer, when actively driven by the current bus master, indicates it desires to  
transfer data using 64 bits. REQ64# has the same timing as FRAME#. REQ64# has meaning  
at the end of reset.  
RST#  
Reset is used to bring PCI-specific registers, sequencers and signals to a consistent state.  
SBO# (optional)  
Snoop Backoff is an optional cache support pin which indicates a hit to a modified line when  
asserted. When SBO# is deasserted and SDONE is asserted, it indicates a "clean" snoop  
result.  
SDONE (optional)  
Snoop Done is an optional cache support pin which indicates the status of the snoop for the  
current access. When deasserted, it indicates the result of the snoop is still pending. When  
asserted, it indicates the snoop is complete.  
SERR#  
System Error is for reporting address parity errors, data parity errors on the Special Cycle  
command, or any other system error where the result will be catastrophic. If an agent does not  
want a non-maskable interrupt (NMI) to be generated, a different reporting mechanism is  
required.

STOP#  
Stop indicates that the current target is requesting the master to stop the current transaction.  
TCK (optional)  
Test Clock is used to clock state information and test data into and out of the device during  
operation of the TAP (Test Access Port).  
TDI (optional)  
Test Data Input is used to serially shift test data and test instructions into the device during TAP  
(Test Access Port) operation.  
TDO (optional)  
Test Data Output is used to serially shift test data and test instructions out of the device during  
TAP (Test Access Port) operation.  
TMS (optional)  
Test Mode Select is used to control the state of the TAP (Test Access Port) controller in the  
device.  
TRDY#  
Target Ready indicates the target agent’s (selected device’s) ability to complete the current data  
phase of the transaction. TRDY# is used in conjunction with IRDY#. During a read, TRDY#  
indicates that valid data is present on AD[31::00]. During a write, it indicates that the target is  
prepared to accept data.  
TRST# (optional)  
Test Reset provides an asynchronous initialization of the TAP controller. This signal is optional  
in the IEEE Standard Test Access Port and Boundary Scan Architecture.

Chapter 3  
System BIOS  
BIOS OPERATION  
Sections 3 through 8 of this manual describe the operation of the American Megatrends  
AMIBIOS and the AMIBIOS Setup Utility. Refer to Running AMIBIOS Setup later in  
this chapter for standard Setup screens, options and defaults. The available Setup  
screens, options and defaults may vary if you have a custom BIOS.  
When the system is powered on, AMIBIOS performs the Power-On Self Test (POST)  
routines. These routines are divided into two phases:  
1) System Test and Initialization. Test and initialize system boards for  
normal operations.  
2) System Configuration Verification. Compare defined configuration with  
hardware actually installed.  
If an error is encountered during the diagnostic tests, the error is reported in one of two  
different ways. If the error occurs before the display device is initialized, a series of  
beeps is transmitted. If the error occurs after the display device is initialized, the error  
message is displayed on the screen. See BIOS Errors later in this section for more infor-  
mation on error handling.  
The following are some of the Power-On Self Tests (POSTs) which are performed when  
the system is powered on:  
CMOS Checksum Calculation  
Keyboard Controller Test  
CMOS Shutdown Register Test  
8254 Timer Test  
Memory Refresh Test  
Display Memory Read/Write Test  
Display Type Verification  
Entering Protected Mode  
Memory Size Calculation  
Conventional and Extended Memory Test  
DMA Controller Tests  
Keyboard Test  
System Configuration Verification and Setup  
_______________________________________________________________________  
NOTE: When you perform a warm boot by pressing <Ctrl> + <Alt> + <Del>, all  
memory tests are bypassed.  
_______________________________________________________________________  
AMIBIOS checks system and cache memory and reports them on both the initial  
AMIBIOS screen and the AMIBIOS System Configuration screen which appears after  
POST is completed. AMIBIOS attempts to initialize the peripheral devices by verifying  
Chassis Plans  
3-1  
 
System BIOS  
CBI/CGI Technical Reference  
the validity of the system setup information stored in the system CMOS RAM. (See  
Running AMIBIOS Setup later in this chapter.) If AMIBIOS detects a fault, the screen  
displays the error condition(s) which has/have been detected. If no errors are detected,  
AMIBIOS attempts to load the system from any bootable device, such as a floppy disk or  
hard disk.  
Normally, the only POST routine visible on the screen is the memory test. The following  
screen displays when the system is powered on:  
AMIBIOS (C)1998 American Megatrends Inc.  
TRENTON Technology Inc.  
Hit DEL if you want to run SETUP  
Initial Power-On Screen  
You have two options:  
Press <Del> to access the AMIBIOS Setup Utility.  
This option allows you to change various system parameters such as date  
and time, disk drives, etc. The Running AMIBIOS Setup section of this  
manual describes the options available.  
You may be requested to enter a password before gaining access to the  
AMIBIOS Setup Utility. (See Password Entry later in this section.)  
If you enter the correct password or no password is required, the AMIBIOS  
Setup Main Menu displays. (See Running AMIBIOS Setup later in this  
section.)  
Allow the bootup process to continue without invoking the AMIBIOS Setup  
Utility.  
In this case, after AMIBIOS loads the system, you may be requested to enter  
a password. (See Password Entry later in this section.)  
Once the POST routines complete successfully, a screen displays showing the current  
configuration of your system, including processor type, base and extended memory  
amounts, floppy and hard drive types, display type and peripheral ports.  
In systems with more than 1MB, AMIBIOS reports 384KB less RAM than it finds,  
because it accounts for the address space between 640K and 1024K which is unavailable  
to DOS. This space is used for video RAM, video BIOS, system BIOS and adapter  
ROMs.

Password Entry  
The system may be configured so that the user is required to enter a password each time  
the system boots or whenever an attempt is made to enter AMIBIOS Setup. The  
password function may also be disabled so that the password prompt does not appear  
under any circumstances.  
The Password Check option in the Advanced CMOS Setup program allows you to  
specify when the password prompt displays: Always or only when Setup is attempted.  
The supervisor and user passwords may be changed using the Change Supervisor  
Password and Change User Password options on the AMIBIOS Setup Main Menu. If  
the passwords are null, the password prompt does not display at any time. A more  
detailed description of the password setup function may be found in the Running  
AMIBIOS Setup section later in this chapter.  
When password checking is enabled, the following password prompt displays:  
Enter CURRENT Password:  
Type the password and press <Enter>.  
_______________________________________________________________________  
NOTE: The null password is the system default and is in effect if a password has not  
been assigned or if the CMOS has been corrupted. In this case, the password prompt  
does not display. To set up passwords, you may use the Change Supervisor Password  
and Change User Password options on the AMIBIOS Setup Main Menu. (See Running  
AMIBIOS Setup later in this chapter.)  
_______________________________________________________________________  
If an incorrect password is entered, the following screen displays:  
Enter CURRENT Password: X  
Enter CURRENT Password:  
Chassis Plans  
3-3  
 
System BIOS  
CBI/CGI Technical Reference  
You may try again to enter the correct password. If you enter the password incorrectly  
three times, the system responds in one of two different ways, depending on the value  
specified in the Password Check option on the Advance CMOS Setup screen:  
1) If the Password Check option is set to Setup, the system does not let you  
enter Setup, but does continue the booting process. You must reboot the  
system manually to retry entering the password.  
2) If the Password Check option is set to Always, the system locks and you  
must reboot. After rebooting, you will be requested to enter the password.  
Once the password has been entered correctly, you are allowed to continue.  
BIOS Errors  
If an error is encountered during the diagnostic checks performed when the system is  
powered on, the error is reported in one of two different ways:  
1) If the error occurs before the display device is initialized, a series of beeps is  
transmitted.  
2) If the error occurs after the display device is initialized, the screen displays  
the error message. In the case of a non-fatal error, a prompt to press the  
<F1> key may also appear on the screen.  
Explanations of the beep codes and BIOS error messages may be found in Appendix A -  
BIOS Messages.  
As the POST routines are performed, test codes are presented on Port 80H. These codes  
may be helpful as a diagnostic tool and are listed in Appendix A - BIOS Messages.  
If certain non-fatal error conditions occur, you are requested to run the AMIBIOS Setup  
Utility. The error messages are followed by this screen:  
AMIBIOS (C)1998 American Megatrends, Inc.

RUNNING  
AMIBIOS SETUP  
AMIBIOS Setup keeps a record of system parameters, such as date and time, disk drives,  
display type and other user-defined parameters. The Setup parameters reside in the Read  
Only Memory Basic Input/Output System (ROM BIOS) so that they are available each  
time the system is turned on. AMIBIOS Setup stores the information in the comple-  
mentary metal oxide semiconductor (CMOS) memory. When the system is turned off, a  
backup battery retains system parameters in the CMOS memory.  
Each time the system is powered on, it is configured with these values, unless the CMOS  
has been corrupted or is faulty. The AMIBIOS Setup Utility is resident in the ROM  
BIOS so that it is available each time the computer is turned on. If, for some reason, the  
CMOS becomes corrupted, the system is configured with the default values stored in this  
ROM file.  
As soon as the system is turned on, the power-on diagnostic routines check memory,  
attempt to prepare peripheral devices for action, and offer you the option of pressing  
<Del> to run AMIBIOS Setup.  
If certain non-fatal errors occur during the Power-On Self Test (POST) routines which  
are run when the system is turned on, you may be prompted to run AMIBIOS Setup by  
pressing <F1>.

AUTO-DETECT  
HARD DISKS  
The Auto-Detect Hard Disks option allows you to have AMIBIOS automatically detect  
the type of hard disk drive(s) in your system. The automatic detection functions only if  
you have IDE drives. The parameters are reported on the Standard CMOS Setup screen.  
AMIBIOS searches first for the primary master and slave hard disk drives, then for the  
secondary master and slave drives. If it can access a drive, it reads the disk parameters.  
It then searches the AMIBIOS drive type table for matching parameters to determine the  
disk type and displays both the type and parameters on the screen. If no matching  
parameters are found in the table, AMIBIOS specifies the type as "User" and fills in the  
parameter values it found on the drive. If it cannot access the drive or if it is not an IDE  
drive, AMIBIOS times out and specifies that the disk drive is "Not Installed."  
_______________________________________________________________________  
NOTE: The auto detect feature displays disk parameter values as established by the  
drive manufacturer. If the drive has been formatted using any other values, accepting the  
auto detect values will cause erratic behavior. You must either reformat the drive to meet  
the manufacturer's specifications or use Standard CMOS Setup to enter parameters which  
match the current format of the drive.  
_______________________________________________________________________  
If you do not want to accept the hard disk type and its associated parameters as reported  
by AMIBIOS or if the drive is "Not Installed," you may use Standard CMOS Setup to set  
up the correct parameters for the drive.  
Once the parameters are correct for all of the drives, you may exit from the Standard  
CMOS Setup screen and save the settings in the CMOS.  
CHANGE  
PASSWORD  
AMIBIOS Setup has an optional password feature which can be configured so that a  
password must be entered each time the system boots or just when a user attempts to  
enter AMIBIOS Setup. (See the Advanced CMOS Setup section of this manual for infor-  
mation on how to enable the Password Check option.)  
The Change Supervisor Password and Change User Password options on the  
AMIBIOS Setup Main Menu allow you to establish passwords, change the current  
passwords or disable the password prompts by entering null passwords. The passwords  
are stored in CMOS RAM.  
The Change User Password function is accessible only if the supervisor password has  
been established previously. If you have signed on under the user password, you cannot  
change the supervisor password.  
_______________________________________________________________________  
NOTE: The null password is the system default and is in effect if a password has not  
been assigned or if the CMOS has been corrupted. In this case, the "Enter CURRENT  
Password" prompt is bypassed when you boot the system, and you must establish a new  
password.  
_______________________________________________________________________  
CHANGE  
If you select the Change Supervisor Password option, the following window displays:  
SUPERVISOR  
PASSWORD  
Enter new supervisor password: _  
Chassis Plans  
3-11  
 
System BIOS  
CBI/CGI Technical Reference  
This is the message which displays before you have established a password or if the last  
password entered was the null password. If a password has already been established, you  
are asked to enter the current password before being prompted to enter the new  
password.  
Type the new password and press <Enter>. The password cannot exceed six (6)  
characters in length. The screen does not display the characters as you type them.  
After you have entered the new password, the following window displays:  
Retype new supervisor password: _  
Re-key the new password as described above.  
If the password confirmation is miskeyed, AMIBIOS Setup displays the following  
message:  
Incorrect password, press any key to continue  
No retries are permitted; you must restart the procedure from the AMIBIOS Setup Main  
Menu.  
If the password confirmation is entered correctly, the following message displays:  
New supervisor password installed, press any key to continue  
When you press any key, the screen returns to the AMIBIOS Setup Main Menu screen,  
which allows you to save the password change or exit from Setup without saving the new  
password. To save the new password in CMOS memory, be sure to select Save Settings  
and Exit.  
If you save the changes when you exit AMIBIOS Setup, the password is stored in CMOS  
RAM. The next time the system boots, you are prompted for the password if the  
password function is present and is enabled. (See Advanced CMOS Setup later in this  
manual for an explanation of how to enable password checking.)  
_______________________________________________________________________  
NOTE: Be sure to keep a record of the new password each time it is changed. If you  
forget it, use the Password Clear jumper to reset it to the default (null password). See the  
Specifications chapter of this manual for details.  
_______________________________________________________________________  
CHANGE USER  
PASSWORD  
The Change User Password function is accessible only if the supervisor password has  
been established previously.

The Change User Password option is similar in functionality to the Change Supervisor  
Password and displays the same messages, except that "user" replaces "supervisor." If  
you have signed on under the user password, you cannot change the supervisor  
password.  
DISABLING THE  
PASSWORD(S)  
To disable password checking so that the password prompt does not appear under any  
circumstances, you may create null passwords using the Change Supervisor Password  
and Change User Password functions by pressing <Enter> without typing in a new  
password. You will be asked to confirm the password. Select <Enter> again and the  
following message displays:  
Supervisor password disabled, press any key to continue  
When you press any key, the screen returns to the AMIBIOS Setup Main Menu, which  
allows you to save the password change or exit from Setup without saving the null  
password. To save the null password(s) in CMOS memory, be sure to select Save  
Settings and Exit.  
AUTO  
CONFIGURATION  
OPTIONS  
Each AMIBIOS Setup option has two default settings (Optimal and Fail Safe). These  
settings can be applied to all AMIBIOS Setup options when you select the appropriate  
auto configuration option from the AMIBIOS Setup Main Menu.  
You can use these auto configuration options to quickly set the system configuration  
parameters which should provide the best performance characteristics, or you can select  
a group of settings which have a better chance of working when the system is having  
configuration-related problems.

through 1F7H, 3F6H and IRQ14. The secondary controller uses I/O port addresses 170H  
through 177H, 376H and IRQ15.  
The AMIBIOS enhanced IDE (EIDE) interface can support IDE Type 4 disk drives.  
This EIDE interface allows disk drives greater than 528MB to be used.  
The hard disk drives can be detected automatically by AMIBIOS (if they are IDE drives)  
or can be defined manually by the user, as described below.

To set up the hard disk drive parameter(s), use the plus (+) key or PgDn key to scroll  
through the drive types to locate the correct type of disk drive(s) in your computer.  
As you scroll through the disk types, the drive Type displays, along with values for size,  
cylinders, heads, write precompensation and sectors. Available predefined hard disk  
drive types are listed at the end of this section. If the parameters supplied by the  
manufacturer of your disk drive do not match any of these preprogrammed drive types,  
you may have AMIBIOS detect the drive type automatically (if it is an IDE drive), or  
you may select the User drive type to enter the parameters manually as described below.  
Set the drive type to CD-ROM to boot from a CD-ROM drive.  
Not Installed is available for use as an option. This option can be used for diskless work  
stations.  
Automatic Detection of Drive Type  
If any of the hard disks are IDE drives, AMIBIOS can automatically configure the drive  
type by detecting the IDE drive parameters and reporting them on the Standard CMOS  
Setup screen.  
You may invoke automatic detection of IDE drives in one of three ways:  
Press Enter when the cursor is in the Type field. AMIBIOS detects the  
drive type and parameters as requested. If the drive type is not defined in  
the drive type table, this option displays User as the drive type and displays  
the parameters which were detected by AMIBIOS. The detected drive type  
values may then be saved in the CMOS.  
Chassis Plans  
4-3  
 
Standard CMOS Setup  
CBI/CGI Technical Reference  
Set the drive type to Auto to have AMIBIOS detect the drive type and  
parameters automatically each time the system is booted up. This option  
does not display the drive type on the Standard CMOS Setup screen, but  
does display it on the System Configuration screen shown after a successful  
bootup.  
Select the Auto-Detect Hard Disks option on the AMIBIOS Setup Main  
Menu to have AMIBIOS automatically detect the type and parameters of  
each hard drive and place the information into the Standard CMOS Setup  
screen. The detected drive type values may then be saved in the CMOS.  
This option is described in the Running AMIBIOS Setup section of the  
System BIOS chapter of this manual.  
_______________________________________________________________________  
NOTE: The auto detect feature displays disk parameter values as established by the  
drive manufacturer. If the drive has been formatted using any other values, accepting the  
auto detect values will cause erratic behavior. You must either reformat the drive to meet  
the manufacturer's specifications or use the User type to enter parameters which match  
the current format of the drive.  
_______________________________________________________________________  
User-Defined Drive Types  
If the parameters supplied by the manufacturer of your disk drive do not match any of the  
preprogrammed drive types provided by AMIBIOS, you may enter the parameters  
manually.  
The user-defined parameters for each of the four drives may be different, which effec-  
tively allows four different user-definable hard disk types.  
Scroll to the end of the drive type list to the User type. You can manually enter the Cyln,  
Head, WPcom and Sec parameters. The Size parameter is automatically calculated and  
displayed by the system based on the other parameters entered.  
Use the arrow keys or tab key to move between fields. Once you have placed the cursor  
in a field, type in the correct value.  
The following explains the drive parameters which you must enter for a drive type which  
is not in the list:  
Type is the numeric designation for a drive with certain identification param-  
eters.  
Cylinders (Cyln) is the number of disk cylinders found in the specified drive  
type.  
Heads (Head) is the number of disk heads found in the specified drive type.  
Write Precompensation (WPcom) is the read delay circuitry which takes into  
account the timing differences between the inner and outer edges of the surface  
of the disk. The size of the sector gets progressively smaller as the track  
diameter diminishes. Yet each sector must still hold 512 bytes. Write precom-  
pensation circuitry on the hard disk compensates for the physical difference in  
4-4  
Chassis Plans  
 
CBI/CGI Technical Reference  
Standard CMOS Setup  
sector size by boosting the write current for sectors on inner tracks. This  
parameter designates the track (cylinder) number where write precompensation  
begins.  
Sectors (Sec) designates the number of disk sectors per track.  
Size is the formatted capacity of the drive (in megabytes) based on the following  
formula:  
# of heads x # of cylinders x # of sects/cyln x 512 bytes/sect  
IDE Drive Type Setup Options  
For each of the four hard disk drives which is an IDE drive, the following options are  
also available for the drive:  
Logical Block Addressing (LBA) Mode  
This option allows you to enable IDE LBA (Logical Block Addressing) Mode for the  
specified primary or secondary IDE drive. Data is accessed by block addresses rather  
than by the traditional cylinder-head-sector format. This allows you to use drives larger  
than 528MB.  
If LBA Mode is set to On and is supported by the hard disk drive, and if the drive is  
formatted, AMIBIOS enables LBA mode and translates the physical parameters of the  
drive to logical parameters. If a hard disk drive which supports LBA mode and has a  
capacity greater than 528MB was formatted with LBA mode disabled, AMIBIOS does  
not enable LBA mode even if the LBA Mode parameter is set to On in Standard CMOS  
Setup.  
If LBA Mode is set to Off, AMIBIOS uses the physical parameters of the hard disk and  
does not translate parameters. The operating system which uses the parameter table then  
sees only 528MB of hard disk space even if the drive contains more than 528MB.  
Available options are:  
Off  
On  
Block (Blk) Mode  
This option supports transfer of multiple sectors to and from the specified primary or  
secondary IDE drive.  
Block mode boosts IDE drive performance by increasing the amount of data transferred  
during an interrupt. Block mode allows transfers of up to 64KB per interrupt, whereas  
only 512 bytes of data can be transferred per interrupt if block mode is not used.  
If Block Mode is set to On and is supported by the IDE drive, AMIBIOS enables multi-  
sector transfers. AMIBIOS sets the number of sectors to be transferred per interrupt to  
the value returned by the "identify drive" command.

Programmed I/O (PIO) Mode  
IDE PIO mode programs timing cycles between the IDE drive and the programmable  
IDE controller. As the PIO mode increases, the cycle time decreases.  
Set the PIO Mode option to Auto to have AMIBIOS select the PIO mode used by the  
IDE drive being configured. If you select a specific value for the PIO mode, you must  
make absolutely certain that you are selecting the PIO mode supported by the IDE drive  
being configured.

32Bit Mode  
Hard disk drives connected to the SBC via the ISA Bus transfer data 16 bits at a time.  
An IDE drive on the PCI Local Bus can use a 32-bit data path.  
If the 32Bit Mode parameter is set to On, AMIBIOS enables 32-bit data transfers. If the  
host controller does not support 32-bit transfer, this feature must be disabled.  
Available options are:

Chassis Plans  
 
CBI/CGI Technical Reference  
Standard CMOS Setup  
Select ‘Y’ or ‘N’ as appropriate. You may have to select ‘N’ several times to prevent the  
boot sector write.  
The following message displays if any attempt is made to format any cylinder, head or  
sector of any hard disk drive via the BIOS INT 13 Hard Disk Drive Service:  
Format!!! Possible VIRUS: Continue (Y/N)?  
Select ‘Y’ or ‘N’ as appropriate. If you select ‘Y’ to continue, formatting proceeds  
normally. If you do not want to continue formatting, you may have to select ‘N’ several  
times, depending on how many retries are performed by the upper-level software. For  
example, DOS does at least five retries before the Format utility is actually terminated.  
_______________________________________________________________________  
NOTE: You should not enable boot sector virus protection when formatting a hard  
drive.  
_______________________________________________________________________  
The DOS hard disk Format utility does not use INT 13H function AH=05H to format the  
hard disk. It only verifies the hard disk using the INT 13H Verify function (AH=04H).  
The virus warning message is not displayed during DOS hard disk drive formatting.

Quick Boot  
This option allows you to have the AMIBIOS boot quickly when the computer is  
powered on or go through more complete testing.  
When this option is set to Disabled, AMIBIOS tests all system memory. It waits up to  
40 seconds for a READY signal from the IDE hard disk drive. It waits for .5 seconds  
after sending a RESET signal to the IDE drive to allow the drive time to get ready again.  
It also checks whether the user has pressed the <Del> key and runs the AMIBIOS Setup  
program if the key has been pressed.  
If the option is set to Enabled, AMIBIOS checks only the first 1MB of system memory.  
It does not wait up to 40 seconds for a READY signal from the IDE hard disk drive. If a  
READY signal is not received immediately, AMIBIOS does not configure the drive. It  
does not wait for .5 seconds after sending a RESET signal to the IDE drive to allow the  
IDE drive time to get ready again.  
If you have set your system up for a quick boot, you cannot run AMIBIOS Setup at

Video or Adapter ROM Shadow  
ROM shadow is a technique in which BIOS code is copied from slower ROM to faster  
RAM. The BIOS is then executed from the RAM.  
Each option allows for a segment of 16KB to be shadowed from ROM to RAM. If one  
of these options is enabled and there is BIOS code present in that particular segment, the  
BIOS is shadowed.  
Video BIOS shadowing may be done in two 16KB segments at C000H and C400H.  
Enabling shadowing can speed up the operation of a machine because RAM can be

for the video BIOS segments is Cached.  
Other 16KB ROM segments may be shadowed in the memory area from C800H to  
E000H, depending upon preferences and system requirements. The ROM area that is not  
used by ISA adapter cards is allocated to PCI adapter cards.  
The Setup screen displays the system option:  
XXXX,16K Shadow  
where XXXX is the base address of the segment of memory to be shadowed.  
Three options are available:

Select Enabled to write the contents of the specified ROM area to the same  
address in system memory (RAM) for faster execution.  
Select Cached to write the contents of the specified ROM area to the same  
address in system memory (RAM), if an adapter ROM is using the ROM  
area. This also indicates that the contents of the RAM area can be read from  
and written to cache memory.  
Select Disabled if you do not want to copy the specified ROM area to  
RAM. The contents of the video ROM cannot be read from or written to  
cache memory.

Three options are available:  
None - No error checking or error reporting is done.  
EC - Multibit errors are detected and reported as parity errors. Single-bit  
errors are corrected by the chipset. Corrected bits of data from memory are  
not written back to DRAM system memory.  
ECC Hardware - Multibit errors are detected and reported as parity errors.  
Single-bit errors are corrected by the chipset and are written back to DRAM  
system memory.  
If a soft (correctable) memory error occurs, writing the fixed data back to  
DRAM system memory will resolve the problem. Most DRAM errors are  
soft errors. If a hard (uncorrectable) error occurs, writing the fixed data  
back to DRAM system memory does not solve the problem. In this case, the  
second time the error occurs in the same location, a Parity Error is reported,  
indicating an uncorrectable error.

PCI VGA Palette Snoop  
Palette snooping allows multiple VGA devices operating on different buses to handle  
data from the processor on each set of palette registers on every video device, e.g. if there  
are two VGA devices in your system (one PCI and one ISA). Bit 5 of the command  
register in the PCI device configuration space is the VGA Palette Snoop bit (0 is  
disabled).  
This option must be set to Enabled if any ISA adapter card installed in the system  
requires VGA palette snooping.  
The Setup screen displays the system option:  
PCI VGA Palette Snoop  
Two options are available:  
Disabled  
Disabled - Data read and written by the processor is only directed to the PCI  
VGA device's palette registers.  
Enabled - Data read and written by the processor is directed to both the PCI  
VGA device's palette registers and the ISA VGA device's palette registers,  
permitting the palette registers of both devices to be identical.  
PCI IDE BusMaster  
This option specifies whether the IDE controller on the PCI Local Bus has bus mastering  
capability. AMIBIOS can perform bus master transfers using scatter/gather DMA on the  
PCI IDE interface. No special drivers are needed, but the IDE drive must support PCI  
bus mastering.

PERIPHERAL  
SETUP OPTIONS  
The descriptions for the system options listed below show the values as they appear if  
you have not yet run Peripheral Setup. Once values have been defined, they display each  
time Peripheral Setup is run.  
The AMIBIOS allows automatic or manual setup of peripheral devices. The floppy  
drive controller, serial port, parallel port and IDE controller options on the Peripheral  
Setup screen can each be set to Auto, which causes AMIBIOS to configure the periph-  
erals automatically as described under each heading below.  
When you set these options to values other than Auto, the values you set up manually are  
used by AMIBIOS when booting the system. AMIBIOS reports any I/O conflicts after  
displaying the BIOS Configuration Summary screen.

CBI/CGI Technical Reference  
OnBoard FDC  
The on-board floppy drive controller may be enabled or disabled using this option.  
When this option is set to Auto, AMIBIOS attempts to enable any floppy drive controller  
on the ISA Bus. If no floppy controller is found on the ISA Bus, the on-board floppy  
controller is enabled.  
The Setup screen displays the system option:  
OnBoard FDC

When this option is set to Auto, AMIBIOS also attempts to avoid address conflicts. If  
the off-board serial ports are configured to specific starting I/O ports via jumper settings,  
AMIBIOS configures the on-board serial ports to avoid conflicts.  
AMIBIOS checks the ISA Bus for serial ports. Any off-board serial ports found on the  
ISA Bus are left at their assigned addresses. Serial Port 1, the first on-board serial port,  
is configured with the first available address and Serial Port 2, the second on-board serial  
port, is configured with the next available address. The default address assignment order  
is 3F8H, 2F8H, 3E8H, 2E8H. Note that this same assignment order is used by  
AMIBIOS to place the active serial port addresses in lower memory (BIOS data area) for  
configuration as logical COM devices.  
After all addresses have been assigned, any remaining on-board serial ports are disabled.

For example, if there is one off-board serial port on the ISA Bus and its address is set to  
2F8H, Serial Port 1 is assigned address 3F8H and Serial Port 2 is assigned address 3E8H.  
Configuration is then as follows:  
COM1 - Serial Port 1 (at 3F8H)  
COM2 - off-board serial port (at 2F8H)  
COM3 - Serial Port 2 (at 3E8H)

When this option is set to Auto, AMIBIOS checks the ISA Bus for off-board parallel  
ports. Any parallel ports found on the ISA Bus are left at their assigned addresses. The  
on-board Parallel Port is automatically configured with the first available address not  
used by an off-board parallel port. The default address assignment order is 3BCH, 378H,  
278H. Note that this same assignment order is used by AMIBIOS to place the active  
parallel port addresses in lower memory (BIOS data area) for configuration as logical  
LPT devices.  
Parallel Port Mode  
This option specifies the parallel port mode. ECP and EPP are both bidirectional data  
transfer schemes which adhere to the IEEE P1284 specifications.  
The Setup screen displays the system option:  
Parallel Port Mode  
ECP  
Three options are available:  
Normal uses normal parallel port mode.  
EPP allows the parallel port to be used with devices which adhere to the  
Enhanced Parallel Port (EPP) specification. EPP uses the existing parallel  
port signals to provide asymmetric bidirectional data transfer driven by the  
host device.

Appendix A BIOS Messages  
BIOS BEEP CODES Errors may occur during the POST (Power-On Self Test) routines which are performed  
each time the system is powered on.  
Non-fatal errors are those which, in most cases, allow the system to continue the bootup  
process. The error message normally appears on the screen. See BIOS Error Messages  
later in this appendix for descriptions of these messages.  
Fatal errors are those which will not allow the system to continue the bootup procedure.  
These fatal errors are usually communicated through a series of audible beeps. Each  
error message has its own specific beep code, defined by the number of beeps following  
the error detection. The following table lists the errors which are communicated audibly.  
All errors listed, with the exception of #8, are fatal errors.

Host Adapter SCSI ID  
Each device on the SCSI bus, including the adapter, must have a unique SCSI ID.  
Allowable IDs are 0 through 7 on 8-bit adapters, and 0 through 15 on 16-bit adapters.  
The SCSI ID serves two purposes:  
1) It uniquely defines each SCSI device on the bus.  
2) It determines which device controls the bus when two or more devices try to  
use the bus at the same time. For 8-bit devices, SCSI ID 7 has the highest  
C-4  
Chassis Plans  
 
CBI/CGI Technical Reference  
priority and SCSI ID 0 has the lowest priority. For 16-bit devices, the  
priority of IDs is 7 through 0, then 15 through 8,with SCSI ID 7 having the  
highest priority and SCSI ID 8 having the lowest priority.  
All adapters (8-bit and 16-bit) have a default SCSI ID of 7, which gives the host adapter  
the highest priority on the SCSI bus.  
Available options are:  
8-bit Adapters:  
0 through 7  
16-bit Adapters:  
0 through 15  
SCSI Parity Checking  
Each adapter uses SCSI parity checking to verify the accuracy of data transfer on the  
SCSI bus. By default, parity checking is set to Enabled.  
Most currently available SCSI devices support SCSI parity. However, if a device on the  
SCSI bus does not support SCSI parity, set the SCSI Parity Checking option to  
Disabled.  
Available options are:  
Enabled  
Disabled  
Host Adapter SCSI Termination  
A set of resistors, called terminators, must be either installed in or enabled on the first  
and last SCSI devices on each SCSI bus; otherwise, the devices will not operate properly.  
Because the adapter is usually the SCSI device at one end of the bus, adapter termination  
for an 8-bit adapter is set to Enabled by default. If an 8-bit adapter is not at the end of  
the SCSI bus, set the Host Adapter SCSI Termination option to Disabled.  
On 16-bit adapters, termination is enabled for both the low byte (bits 0-7) and the high  
byte (bits 8-15). The table on the next page shows appropriate termination settings for a  
16-bit adapter:  
Available options are:  
8-bit Adapters:  
Enabled  
Disabled  
16-bit Adapters:  
Low ON/High ON  
Low OFF/High OFF

and then return to the SCSI Device Configuration screen.  
SCSI DEVICE  
SETTINGS  
The settings for each SCSI device on the SCSI bus can be modified individually as  
described below.  
Initiate Sync Negotiation  
Synchronous negotiation is a SCSI feature that allows the SCSI adapter and its attached  
SCSI devices to transfer data in synchronous mode. Synchronous data transfer is faster  
than asynchronous data transfer.  
C-8  
Chassis Plans  
 
CBI/CGI Technical Reference  
The Initiate Sync Negotiation setting determines whether the adapter initiates  
synchronous negotiation with the SCSI device. If this option is set to the default setting  
of Yes, the adapter initiates synchronous negotiation with the SCSI device. Normally,  
you should leave this option set to Yes, because most SCSI devices support synchronous  
negotiation, which allows for faster data transfer. If a device does not support  
synchronous negotiation, the adapter automatically transfers the data in asynchronous  
mode.  
If you change the setting to No, the adapter does not initiate synchronous negotiation;  
however, the adapter always responds to synchronous negotiation if the SCSI device  
initiates it. If neither the adapter nor the SCSI device negotiates for synchronous data  
transfers, data is transferred in asynchronous mode.

Maximum Sync Transfer Rate  
This setting determines the maximum synchronous data transfer rate that the adapter will  
negotiate with the device. The adapter automatically negotiates for the rate requested by  
the device. The allowable maximum rates are in megabytes.  
If the adapter is set not to negotiate for synchronous data transfer (i.e., if the Initiate  
Sync Negotiation option is set to No), the value selected here is the maximum rate at  
which the adapter accepts data from the device during negotiation. This is standard SCSI  
protocol.  
If the Support for Ultra SCSI Speed option on the Advanced Configuration Options  
screen is disabled, the only values available for maximum sync transfer rate are those for  
8-bit adapters (see below); in this case, the default is 20.0. If Support for Ultra SCSI  
Speed is enabled, the values for 16-bit adapters are available and the default is 40.0.  
Available options are:  
8-bit Adapters:  
20.0  
16.0  
13.4  
10.0  
16-bit Adapters:  
40.0

Enable Disconnection  
This setting determines whether the adapter allows a SCSI device to disconnect from the  
SCSI bus (sometimes called Disconnect/Reconnect). Enabling disconnection allows the  
Chassis Plans  
C-9  
 
CBI/CGI Technical Reference  
adapter to perform other operations on the SCSI bus while the SCSI device is tempo-  
rarily disconnected.  
When the Enable Disconnection option is set to the default setting of Yes, the SCSI  
device may disconnect from the SCSI bus. The SCSI device may choose not to  
disconnect, however, even if permitted by the adapter (this can usually be configured on  
the SCSI device). When this option is set to No, the SCSI device cannot disconnect from  
the SCSI bus.  
Leave the Enable Disconnection option set to Yes if the adapter connects to two or more  
SCSI devices. This optimizes SCSI bus performance. If the adapter connects to only  
one SCSI device, set this option to No to achieve slightly better performance.  
Available options are:  
Yes  
No  
Initiate Wide Negotiation  
This option, which only displays for 16-bit adapters, lets the adapter initiate wide negoti-  
ation with a 16-bit SCSI device. The adapter will not attempt wide negotiation with 8-bit  
devices, so you can leave this option set to Yes even if the bus includes 8-bit devices.  
Available options are:  
Yes  
No  
Send Start Unit Command  
This setting determines whether the adapter sends the Start Unit command (SCSI  
command 1B) to the SCSI device. The default setting for Send Start Unit Command is  
No (disabled).  
Enabling this option reduces the load on a computer's power supply by allowing the  
adapter to turn on SCSI devices one by one when the computer boots; otherwise, all  
SCSI devices turn on at the same time. Before you enable this option for a device, make  
sure the AIC-7880 BIOS is enabled. Also, check the device documentation to make sure  
the device supports the command. On most devices, you must also change a switch or  
jumper setting on the device to enable the device to respond to the command.  
If you enable Send Start Unit Command for more than one SCSI device, the adapter  
first sends the Start Unit command to the boot device specified in the Boot Target ID  
option of the Boot Device Configuration screen. When the boot device responds, Start  
Unit commands are sent to the remaining devices, beginning with the device with the  
lowest SCSI ID. The boot time varies depending on how long each drive takes to spin  
up.

Include in BIOS Scan  
This option indicates whether or not the specified SCSI device should be included in a  
scan of the devices which is done during bootup. Setting this option to No for devices  
which are not attached saves time during bootup since the BIOS will not spend time  
checking for unassigned devices.

The Advanced Configuration Options screen displays the current settings for the selected  
adapter and allows you to change these settings.  
Plug and Play Scam Support  
When this option is set to Enabled, it allows the adapter to automatically assign a SCSI  
ID to an attached SCSI device that supports SCAM-1 (SCSI Configured AutoMatically)  
protocol. Most non-SCAM devices tolerate SCAM protocol, so you can usually enable  
this option even if you have some non-SCAM devices. In rare cases, an old SCSI-1  
device may not tolerate SCAM and may cause your computer to hang or operate errati-  
cally. If this happens, set the option back to Disabled.  
The default for this option is Disabled. When you attempt to change it to Enabled, the  
following informational message displays:  
WARNING: ‘Reset SCSI Bus at IC Initialization’ cannot be DISABLED  
if ‘Plug and Play Scam Support’ is ENABLED.

Host Adapter BIOS  
This option enables or disables the AIC-7880 BIOS. The BIOS must be enabled if you  
want the computer to boot from a SCSI hard disk drive connected to the adapter. In  
addition, the BIOS must be enabled if you want to enable any of the following options:  
Support Removable Disks Under BIOS as Fixed Disks  
Extended BIOS Translation for DOS Drives > 1 GByte  
Multiple LUN Support  
BIOS Support for Bootable CD-ROM  
BIOS Support for Int 13 Extensions  
Support for Ultra SCSI Speed  
Send Start Unit SCSI Command  
If the devices on the SCSI bus are controlled by device drivers (and therefore do not need  
a BIOS), you can disable the AIC-7880 BIOS to free about 16KB of memory. This also  
shortens the boot time by up to 60 seconds.  
Available options are:  
Enabled

Support Removable Disks Under BIOS as Fixed Disks  
This setting controls which removable-media drives are supported by the AIC-7880  
BIOS.  
When you attempt to change the setting of this option, the following informational  
message displays:  
WARNING: Do not remove media from a removable media drive if  
it is under BIOS control.  
Chassis Plans  
C-13  
 
CBI/CGI Technical Reference  
Available options are:  
Boot Only - Only the removable-media drive designated as the boot device  
is treated as a hard disk drive. This is the default option.  
All Disks - All removable-media drives supported by the AIC-7880 BIOS  
are treated as hard drives. This setting has no effect on drives under  
NetWare, because NetWare automatically supports removable-media drives  
as fixed disks.  
Disabled - No removable-media drives running under DOS are treated as  
hard disk drives. In this situation, driver software is needed, because the  
drives are not controlled by the BIOS.  
Extended BIOS Translation for DOS Drives > 1 GByte  
All current versions of MS-DOS are limited to 1024 cylinders per drive. The standard  
translation scheme for SCSI host adapters, using 64 heads and 32 sectors, provides a  
maximum accessible capacity of 1 GByte. To support disk drives larger than 1 GByte,  
the AIC-7880 BIOS includes an extended translation scheme that supports disk drives as  
large as 8 GBytes under MS-DOS.  
This option is not available if the Host Adapter BIOS option is set to Disabled. The  
default for this option is Enabled and should not be changed. With extended translation  
enabled, drives handled by the AIC-7880 BIOS use extended translation if their  
formatted capacity is greater than 1 GByte, and drives smaller than 1 GByte use standard  
translation.  
_______________________________________________________________________  
NOTE: If you decide to change the translation scheme, be sure to back up the disk  
drives first. All data is erased when you change from one translation scheme to another.  
_______________________________________________________________________  
When you partition a disk larger than 1 GByte, use the MS-DOS fdisk utility as you  
normally would. Because the cylinder size increases up to 8MB under extended trans-  
lation, the partition size you choose must be a multiple of 8MB. If you request a size that  
is not a multiple of 8MB, fdisk rounds up to the nearest whole multiple of 8MB.  
Available options are:  
Enabled  
Disabled  
Display <Ctrl-A> Message During BIOS Initialization  
This option has no effect since the configuration utility is invoked using the cfg7880.exe  
program.  
Multiple LUN Support  
This option allows the BIOS to support multiple logical units. Set this option to Enabled  
if any devices have multiple logical units.

BIOS Support for Int 13H Extensions  
When this option is set to Enabled, the adapter BIOS supports El Torito Int 13H exten-  
sions, which are required for bootable CD-ROMs. You can disable this option if the boot  
device is not a CD-ROM, but it is not necessary to do so.

SCSI drives are preformatted and need not be formatted again. If a drive is not prefor-  
matted, you can use SCSISelect to perform a low-level format on the drive. The  
formatting is compatible with most SCSI disk drives.  
_______________________________________________________________________  
NOTE: A low-level format destroys all data on the drive. Be sure to back up your data  
before performing this operation. You cannot abort a low-level format once it starts.
