Introduction

1-1 Overview

SUPER P6SLA/P6SLE supports single Pentium II. They are
based on Intel’s 440 LX chipset which enables Accelerated
Graphics Port (AGP), Wake-on-LAN, SDRAM, concurrent PCI and
Ultra DMA 33 MB/s burst data transfer rate.

SUPER P6SLA/P6SLE is ATX size and have 4 PCI slots, 3 ISA
slots and an AGP connector. These motherboards accommodate
a total of 768 MB EDO or 384 MB SDRAM memory with 3 168-pin
DIMM sockets.

AGP reduces contention with the CPU and I/O devices by broad­ening the bandwidth of graphics to memory. It delivers a maxi­mum of 532 MB/s 2x transfer mode which is quadruple the PCI
speed!

Wake-on-LAN allows remote network management and configura­tion of the PC, even in off-hours when the PC is turned off. This
reduces the complexity of managing the network.

Other features that maximize customer satisfaction and simplicity
in managing the computer are PC 98-ready and support for
Advanced Configuration and Power Interface (ACPI). With PC
Health Monitoring, you can protect your system from problems
before they even occur.

Included I/O on Super P6SLA/P6SLE are 2 EIDE ports, a floppy
port, an ECP/EPP parallel port, PS/2 mouse and PS/2 keyboard, 2
serial ports, an infrared port and 2 USB ports.

1-2 PC Health Monitoring

This section describes the PC health monitoring features of SUPER
P6SLA/P6SLE. It has an on-board W83781D System Hardware
Monitor chip which can support PC health monitoring.

Seven On-Board Voltage Monitors for the CPU Core, CPU I/O,
+3.3V, ±5V, and ±12V

The on-board voltage monitor will scan the seven monitored
voltages every second. Once a voltage becomes unstable, it will
report a warning or an error message on the screen. Users can
adjust the threshold of the monitored voltage to determine the
sensitivity of the voltage monitor.

Three-Fan Status Monitors with Firmware/Software Control On/
Off

The PC health monitor can check the RPM status of the cooling
fans. The on-board 3-pin CPU fan is controlled by the ACPI BIOS
and the ACPI enabled operating system. The thermal fans are
controlled by the overheat detection logic.

Environment Temperature Control

The thermal control sensor will monitor the real-time environment
temperature. It will turn on the back-up fan whenever the environ­ment temperature goes over the user-defined threshold. The
overheat circuitry runs independently from the CPU . It can still
monitor the overheat condition even if the CPU is in sleep mode.
Once it detects that the environment temperature is too high, it
will automatically turn on the back-up fan to prevent any overheat
damage to the CPU. The on-board chassis thermal circuitry can
monitor the overall system temperature and alert users when the
chassis temperature is too high.

CPU Fan Auto-Off in Sleep Mode

The CPU fan will turn on when the power is on. It can be turned
off when the CPU is in sleep mode. When the CPU is in sleep
mode, it means that it will not run at full power, thereby generat­ing less heat. For power saving purposes, the user can have the
option to shut down the CPU fan.

CPU Overheat Alarm and Control

This feature is available when used with SUPERMICRO's SUPER
Doctor Utility. The program will generate a beep sound via the

1-10

Chapter 1: Introduction

speaker when it detects a CPU overheat condition. This overheat
condition can be configured by the user. The program can also
give an indication on the screen when the CPU overheats.

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to
the system. The chassis intrusion connector is located on JL1.
Attach a micro-switch to JL1. When the micro-switch is closed, it
means that the chassis has been opened. The circuitry will then
alert the user with a warning message when the system is on.
The circuitry uses the on-board battery to power up, so even if the
whole system is powered off, the detection can still work properly.

System Resource Alert

This feature is available when used with Intel LANDesk Client
Manager. The user can be notified of certain system events. For
example, if the system is running low on virtual memory, the hard
drive space is not enough to save the data, you are then alerted
of the potential problems.

Hardware BIOS Virus Protection

The system BIOS is protected by hardware so that no virus can
infect the BIOS area. The user can only change the BIOS content
through the flash utility provided by SUPERMICRO. This feature
prevents viruses from infecting the BIOS area and loss of valuable
data. There is also a second way to protect the BIOS from
infection. Please refer to section 5-2-2, Anti-Virus, on page 5-21.

Switching Voltage Regulator for the CPU Core

The switching voltage regulator for the CPU core can support up
to 20A current, with auto-sensing voltage ID ranging from 1.3V to

3.5V. This allows the regulator to run cooler and makes the

system more stable.

Intel LANDesk Client Manager (LDCM) Support

As the computer industry grows, PC systems become more
complex and harder to manage. Historically, only experts could
fully understand and control these complex systems. Today's
users want manageable systems that interact automatically with
the user. Client Manager enables both administrators and clients
to:

1-11

SUPER P6SLA/P6SLE User’s Manual

• Review system inventory

• View DMI-compliant component information

• Back-up and restore system configuration files

• Troubleshoot

• Receive notification for system events

• Transfer files to and from client workstations

• Remotely reboot client workstations

1-3 ACPI/PC 98 Features

ACPI stands for Advanced Configuration and Power Interface. The
ACPI specification defines a flexible and abstract hardware
interface that provides a standard way to integrate power manage­ment features throughout a PC system, including hardware,
operating system and application software. This enables the
system to automatically turn on and off peripherals such as CD­ROMs, network cards, hard disk drives, and printers. This also
includes consumer devices connected to the PC such as VCRs,
TVs, phones, and stereos.

In addition to enabling operating system-directed power manage­ment, ACPI provides a generic system event mechanism for Plug
and Play and an operating system-independent interface for
configuration control. ACPI leverages the Plug and Play BIOS
data structures while providing a processor architecture-indepen­dent implementation that is compatible with both Windows 95 and
Windows NT.

Microsoft OnNow

The OnNow design initiative is a comprehensive, system-wide
approach to system and device power control. OnNow is a term
for a PC that is always on but appears off and responds immedi­ately to user or other requests.

Slow Blinking LED for Sleep-state Indicator

When the CPU goes into a suspend state, the power LED will
start blinking to indicate that the CPU is in sleep mode. When
the user presses any key, the CPU will wake-up and the LED will
automatically stop blinking and remain on.

BIOS Support for USB Keyboard

If the USB keyboard is the only keyboard in the system, the USB
keyboard will work like a normal keyboard during system boot-up.

1-12

Chapter 1: Introduction

Real Time Clock Wake-up Alarm

The PC is perceived to be off when not in use, but is still capable
of responding to previously scheduled wake-up events. The user
can set up a timer to wake-up or shutdown the system at some
predetermined date or time of the month.

Main Switch Override Mechanism

When an ATX power supply is used, the power button can function
as a system suspend button. When the user presses on the
power button, the system will enter a SoftOff state. The monitor
will be suspended, and the hard drive will spin down. Pressing
the power button again will cause the whole system to wake-up.
During the SoftOff state, the ATX power supply provides power to
keep the required circuitry on the system alive. In case the
system malfunctions and you want to turn off the power, just
press down on the power button for approximately 4 seconds.
The power will turn off and no power is provided to the
motherboard.

External Modem Ring-on

Wake-up events can be triggered by a device such as the external
modem ringing when the system is in SoftOff state. When the
modem rings, the system behaves as if a user pressed the
PW_ON button.

1-4 Chipset Overview

The 440LX chipset was developed by Intel as the ultimate
Pentium II processor platform targeted for emerging 3D graphics
and multimedia applications. Along with System-to-PCI bridge
integrated with optimized DRAM controller and data path, the
chipset introduces the Accelerated Graphics Port (AGP) interface.
AGP is a high performance, component level interconnect targeted
at 3D applications and is based on a set of performance en­hancements to PCI. The I/O subsystem portion of the 440LX
platform is based on the PIIX4, a highly integrated version of
Intel's PCI-to-ISA bridge family.

The 440LX PCI/AGP Controller (PAC) system bus interface sup­ports up to two Pentium II processors. It provides an optimized
72-bit DRAM interface (64-bit data plus ECC). This interface
supports 3.3V DRAM technologies. The PAC provides the inter-

1-13

SUPER P6SLA/P6SLE User’s Manual

face to a PCI bus operating at 33 MHz. This interface implemen­tation is compliant with the PCI Rev 2.1 Specification. The AGP
interface is based on the AGP Specification Rev 1.0. It can
support up to 133 MHz (532 MB/s) data transfer rates.

1-5 Wake-On-LAN (WOL)

Wake-on-LAN is defined as the ability of a management applica­tion to remotely power up a computer which is powered off.
Remote PC setup, updates, and asset tracking can occur after
hours and on weekends so daily LAN traffic is kept to a minimum
and users are not interrupted.

The motherboard has a 3-pin header (WOL) used to connect to
the 3-pin header on the Network Interface Card (NIC) which has
WOL capability.

1-6 Power Supply

As with all computer products, a stable power source is neces­sary for proper and reliable operation. It is even more important
for high CPU clock rates like 333, 300, 266, 233 MHz Pentium II
processors.

SUPER P6SLA/P6SLE accommodates ATX power supplies.
Although most power supplies generally meet the specifications
required by the CPU, some power supplies are not adequate.

It is highly recommended that you use a high quality power
supply. Additionally, in areas where noisy power transmission is
present, you may choose to install a line filter to separate noise
from the computer. You can also install a power surge protector
to help avoid problems caused by power surges.

2-1 Static-Sensitive Devices

Static-sensitive electric discharge can damage electronic com­ponents. To prevent damage to your system board, it is important
to handle it very carefully. The following measures are generally
sufficient to protect your equipment from static discharge.

Precautions

• Use a grounded wrist strap designed for static discharge.

• Touch a grounded metal object before you remove the board

from the anti-static bag.

• Handle the board by its edges only; do not touch its compo-

nents, peripheral chips, memory modules, or gold contacts.

• When handling chips or modules, avoid touching their pins.

• Put the system board and peripherals back into their anti-static

bags when not in use.

• For grounding purposes, be sure your computer system’s

chassis allows excellent conductive contacts between its power
supply, case, mounting fasteners, and the system board.

Unpacking

The system board is shipped in anti-static packaging to avoid
static damage. When unpacking the board, be sure the person
handling the board is static-protected.

2-3 Changing the CPU Speed

To change the CPU speed for a Pentium II processor, change the
jumpers shown below on Table 2-1. Refer to Table 2-2 for the
external bus speed jumper settings. The default bus speed is 66
MHz. The following example will show you which CPU Core/Bus
Ratio to use. The general rule is to divide the CPU speed by the
bus speed (66 MHz). If you have a 266 MHz CPU, dividing it by 66
will give you a CPU Core/Bus Ratio of 4. After determining the
CPU Core/Bus Ratio, refer to Table 2-1 for settings of JB1, JB2,
JB3 and JB4.

2-4 Mounting the Motherboard in the Chassis

The motherboard has standard mounting holes to fit different
types of chassis. Chassis may come with a variety of mounting
fasteners, made of metal or plastic. Although a chassis may have
both metal and plastic fasteners, metal fasteners are the most
highly recommended because they ground the system board to
the chassis. Therefore, use as many metal fasteners as possible
for better grounding.

2-6 Installing/Removing the DIMM Modules

SUPER P6SLA/P6SLE can accommodate a maximum of 768 MB
EDO or 384 MB SDRAM. Note: SDRAM requires a minimum of
one bank.

There are three types of EDO and SDRAM DIMM modules: x4, x8
and x16. If you are using the x4 type, you can populate the DIMM
slots with either 4 single-sided memory modules or 2 double­sided memory modules. For memory configurations of 512 MB
EDO DIMMs or higher, it is recommended to use the x8 or x16
type of memory. It is not recommended to mix EDO DIMM mod­ules with SDRAM DIMM modules.

There are no jumpers needed to configure the on-board memory.
Memory timing requires 70ns or faster for EDO memory. Refer to
Figure 2-7 and the instructions below for installing or removing
DIMM modules.

CAUTION

Exercise extreme care when installing or removing the

DIMM modules to prevent any possible damage.

DIMM Module Installation

1. Insert DIMM modules in Bank 0 through Bank 2 as required
for the desired system memory.

2. Insert each DIMM module vertically into its socket. Pay
attention to the two notches to prevent inserting the DIMM at a
wrong position. The component side of the DIMM module
must face the CPU socket. The latter statement is applicable
for DIMMs with components on one side only.

3. Gently press the DIMM module until it snaps upright into place
in the socket.

Removing DIMM Modules

1. Remove DIMM modules in any order.

2. Gently push the edge of the sockets to the side to release the
module. Remove one side of the DIMM module first, and then
the other side, to prevent breaking the socket.

2-7 Connecting Parallel, Floppy and Hard Disk
Drives

Use the following information to connect the floppy and hard disk
drive cables.

• The floppy disk drive cable has seven twisted wires.

• A red mark on a wire typically designates the location of pin 1.

• A single floppy disk drive ribbon cable has 34 wires and two
connectors to provide for two floppy disk drives. The connector
with twisted wires always connects to drive A, and the connec­tor that does not have the twisted wires always connects to
drive B.

• An IDE hard disk drive requires a data ribbon cable with 40
wires, and a SCSI hard disk drive requires a SCSI ribbon cable
with 50 wires. A wide SCSI hard disk drive requires a SCSI
ribbon cable with 68 wires.

• A single IDE hard disk drive cable has two connectors to
provide for two drives. To select an IDE disk drive as C, you
would normally set the drive select jumper on the drive to DS1
(or Master). To select an IDE disk drive as D, you would
normally set the drive select jumper on the drive to DS2 (or
Slave). Consult the documentation that came with your disk
drive for details on actual jumper locations and settings.

• A single SCSI ribbon cable typically has three connectors to
provide for two hard disk drives and the SCSI adapter. (Note:

2-17

SUPER P6SLA/P6SLE User’s Manual

most SCSI hard drives are single-ended SCSI devices.) The
SCSI ID is determined by jumpers or a switch on the SCSI
device. The last internal (and external) SCSI device cabled to
the SCSI adapter must be terminated.

• Some drives require a special controller card. Read your disk
drive manual for details.

3-3 Frequently Asked Questions

Question: How do I update my BIOS?
Answer: Update Bios files are located on our web site at

www.supermicro.com. Please check the current BIOS revision
and make sure it is more current than your BIOS. Select your
motherboard model and the upgrade will be automatically se­lected and downloaded to your computer. Unzip the BIOS update
file and you will find three files: readme.txt (flash instructions),
sm2flash.com (BIOS flash utility), and the BIOS image file
(xxxxxx.rom). Place these files on a bootable floppy and reboot
your system. There are no BIOS boot block protection jumpers on
the motherboard. At the BIOS prompt please enter the command
"sm2flash." This will start the flash utility and give you an oppor­tunity to first save your current file, flash the boot block and enter
the name of the update BIOS image file. NOTE: It is very impor­tant that you save your current BIOS and name it "super.rom" in
case you need to recover from a failed BIOS update. Select flash
boot block, then enter the update BIOS image. Select "Y" to start
the BIOS flash procedure and do not disturb your system until the
flash utility displays that the procedure is complete. After updat­ing your BIOS please clear the CMOS then load and save Optimal
Values in the BIOS.

3-3

SUPER P6SLA/P6SLE User’s Manual

Question: After flashing the BIOS my system does not have
video. How can I correct this?
Answer: Normally, if you do not have video after flashing your

BIOS this indicates the flashing procedure failed. To remedy this,
first clear the CMOS per instructions in this manual and retry. If
you still do not have video, please use the following BIOS recovery
procedure. Turn your system off and place the floppy disk with
the saved BIOS image file (see above FAQ) in drive A. On your
keyboard press and hold "CTRL" and "Home." Turn on power
with the hot keys depressed until your floppy drive is accessed.
Your screen will remain blank until the BIOS program block is
flashed. If your system either rebooted or displays a message to
reboot the system then the procedure was successful.

Question: I have memory problems. What is the correct
memory to use and is there any BIOS setting that may help me?
Answer: The correct memory to use on the P6SLA/P6SLE is 168-

pin DIMM non-buffered SPD (Serial Present Detection) SDRAM,
SDRAM and EDO memory. SPD SDRAM is preferred but is not
necessary. IMPORTANT: Please do not mix memory types; the
results are unpredictable. If your memory count is exactly half of
the correct value, please go to the BIOS in Chipset Setup and
select "SDRAM AUTOSIZING SUPPORT." Change between
available options until one setting correctly displays your memory.

Question: Which Operating System (OS) supports AGP?
Answer: At present Windows 98 and Windows NT 5.0 are the

only OS that will have built-in support for AGP. Some AGP video
adapters can run Windows 95 OSR2.1 with special drivers.
Please contact your graphics adapter vendor for more details.

Question: Do I need the compact disk that came with your
motherboard?
Answer: The supplied compact disc has quite a few drivers and

programs that greatly enhance your system. We recommend that
you review the compact disc and use what you desire. Some of
the items packaged on the compact disc are PCI IDE Bus Master
drivers for Windows 95 and Windows NT, 440LX chipset drivers
for Windows 95, and Super Doctor Monitoring software.

Chapter 3: Troubleshooting

Question: Why can't I turn off the power using the momentary
power on/off switch?
Answer: The instant power off function is controlled by the BIOS.

When this feature is enabled in the BIOS, the motherboard will
have instant off capabilities as long as the BIOS has control of
the system. When this feature is disabled or when the BIOS is
not in control, such as during memory count, the momentary on/off
switch must be held for five seconds before the system will shut
down. These changes were necessary to implement ACPI
features on the motherboard.

Question: I see a few of my PCI devices sharing IRQs. The
system seems to be fine, but is this acceptable?
Answer: Some PCI Bus Mastering devices can share IRQs

without performance penalties. These devices are designed to
work correctly sharing IRQs.

Chapter 4

AMI BIOS

4-1 Introduction

This chapter describes the AMIBIOS for the Intel 440LX Pentium II
233/266/300/333 MHz processors. The AMI ROM BIOS is stored
in the Flash EEPROM and is easily upgraded using a floppy disk­based program.

System BIOS

The BIOS is the basic input output system used in all IBM® PC,
XT™, AT®, and PS/2® compatible computers. The WinBIOS is a
high-quality example of a system BIOS.

Configuration Data

AT-compatible systems, also called ISA (Industry Standard Archi­tecture) must have a place to store system information when the
computer is turned off. The original IBM AT had 64 bytes of non­volatile memory storage in CMOS RAM. All AT-compatible sys­tems have at least 64 bytes of CMOS RAM, which is usually part
of the Real Time Clock. Many systems have 128 bytes of CMOS
RAM.

How Data Is Configured

AMIBIOS provides a Setup utility in ROM that is accessed by
pressing <Del> at the appropriate time during system boot. Setup
configures data in CMOS RAM.

POST Memory Test

Normally, the only visible POST routine is the memory test. The
screen that appears when the system is powered on is shown on
the next page.

An AMIBIOS Identification string is displayed at the left bottom
corner of the screen, below the copyright message.

1st IDE-HDD, 2nd IDE-HDD, 3rd IDE-HDD and 4th IDE-HDD are
the four hard disks than can be installed by the BIOS. 1st IDE­HDD is the first hard disk installed by the BIOS, 2nd IDE-HDD is
the second hard disk, and so on. For example, if the system has
a hard disk connected to Primary Slave and another hard disk to
Secondary Master, then 1st IDE-HDD will be referred to as the
hard disk connected to Primary Slave and 2nd IDE-HDD will be
referred to as the hard disk connected to the Secondary Master.
3rd IDE-HDD and 4th IDE-HDD are not present. Note that the
order of the initialization of the devices connected to the primary
and secondary channels are Primary Master first, Primary Slave
second, Secondary Master third, and Secondary Slave fourth.

5-4

Chapter 5: Running Setup

The BIOS will attempt to read the boot record from 1st, 2nd, 3rd
and 4th boot device in the selected order until it is successful in
reading the booting record. The BIOS will not attempt to boot
from any device which is not selected as the boot device.

Try Other Boot Device

This option controls the action of the BIOS if all the selected boot
devices failed to boot. The settings for this option are Yes or No.
If Yes is selected and all the selected boot devices failed to boot,
the BIOS will try to boot from the other boot devices (in a pre­defined sequence) which are present but not selected as boot
devices in the setup (and hence not yet been tried for booting). If
selected as No and all selected boot devices failed to boot, the
BIOS will try not to boot from the other boot devices which may be
present but not selected as boot devices in setup.

Initial Display Mode

This option determines the display screen with which the POST is
going to start the display. The settings for this option are BIOS or
Silent. If selected as BIOS, the POST will start with the normal
sign-on message screen. If Silent is selected, the POST will start
with the silent screen.

Display Mode at Add-on ROM Init

This option determines the display mode during add-on ROM
(except Video add-on ROM) initialization. The settings for this
option are Force BIOS or Keep Current. If selected as Force
BIOS, the POST will force the display to be changed to BIOS
mode before giving control to any add-on ROM. If no add-on ROM
is found, then the current display mode will remain unchanged
even if this setup question is selected as Force BIOS. If selected
as Keep Current, then the current display mode will remain
unchanged.

Floppy Access Control

The settings for this option are Read-Write or Read-Only.

Hard Disk Access Control

The settings for this option are Read-Write or Read-Only.

by predicting future device failures. The hard disk needs to be
S.M.A.R.T. capable. The settings for this option are Disabled or

Enabled. *Note: SMART cannot predict all future device
failures. SMART should be used as a warning tool, not as a
tool to predict the device reliability.

Boot Up Num-Lock

Settings for this option are On or Off. When this option is set to
On, the BIOS turns off the Num Lock key when the system is

powered on. This will enable the end user to use the arrow keys
on both the numeric keypad and the keyboard.

PS/2 Mouse Support

Settings for this option are Enabled or Disabled. When this
option is set to Enabled, AMIBIOS supports a PS/2-type mouse.

Primary Display

This option specifies the type of display adapter card installed in
the system. The settings are Absent, VGA/EGA, CGA40x25,
CGA80x25 or Mono.

BIOS User's Manual

SDRAM Autosizing Support

If the Serial Presence Detect (SPD) is not available, then the BIOS
will try to detect the memory and do the autosizing. The settings
for this option are Auto, Enabled or Disabled.

EDO DRAM Speed (ns)

This option should be set according to the speed of the EDO
DRAM in the system. The value of this option determines how the
EDO DRAM timings should be programmed in the chipset. The
settings for this option are Auto, Manual, 50, 60 or 70.

EDO Read Burst Timing

Burst mode EDO have internal column counters. Because of this,
they do not need to accept row addresses and starting column
addresses from the EDO memory controller. This eliminates the
setup and hold time for the second and subsequent column
addresses. It also improves the EDO Read access time. The
settings for this option are x333 or x222.

EDO Write Burst Timing

Burst mode EDO have internal column counters. Because of this,
they do not need to accept row addresses and starting column
addresses from the EDO memory controller. This eliminates the
setup and hold time for the second and subsequent column
addresses. It also improves the EDO Write access time. The
settings for this option are x333 or x222.

EDO RAS Precharge

Memory needs to be recharged to ensure the information stored
is not lost. This feature eliminates the RAS (Row Address
Strobe) recharge time since memory must always be addressed
in the order of Row first, then Column. The settings for this
option are 4 Clks or 3 Clks.

EDO RAS to CAS

As previously described, memory must always be addressed in
the order of Row, then Column. The EDO RAS to CAS feature
sets the timing delay between Row addressing and Column
addressing. The settings for this option are 3 Clks or 2 Clks.

MA Waitstate

Use this feature to configure the memory address wait state. The
settings for this option are Slow or Fast.

SDRAM CAS Lat

This feature is for the Column Address Strobe latency. The
settings for this option are 3 Clks or 2 Clks.

SDRAM RAS Precharge

This feature is for the SDRAM Row Address Strobe delay. The
settings for this option are 3 Clks or 2 Clks.

VGA Frame Buffer USWC

USWC is a memory cycle type that stands for Uncacheable
Speculative Write Combining. The settings are: Disabled or
Enabled.

PCI Frame Buffer USWC

The settings for this option are: Disabled or Enabled. When
Enabled, the PCI frame buffer address and length are divided into

2. The value is then programmed into the processor Variable
MTRR (3) with the value for USWC (01h).

DRAM Integrity Mode (ECC)

The settings for this option are: Non ECC, EC only or ECC. Set
this option to Enabled to enable ECC DRAM integrity mode. ECC
allows critical system to detect and correct memory errors, while
normal parity generator/checker can only detect such memory
errors.

Fixed Memory Hole

This option allows a memory hole to be specified for either the
512-640K region or the 15-16M region. The settings for this
option are Disabled, 512-640KB or 15-16MB.

AGP Aperture Size

This register determines the effective size of the Graphics Aper­ture used in the particular PAC configuration. This register can
be updated by the PAC-specific BIOS configuration sequence
before PCI standard bus enumeration sequence takes place. If
the register is not updated, a default value selects aperture of
maximum size (i.e., 256 MB). The settings are: 4 MB, 8 MB, 16
MB, 32 MB, 64 MB, 128 MB or 256 MB.

System Type

The settings are: Auto, DP or UP.

USWC Write I/O Post

Use this feature for the WC Write Post During I/O Bridge Access
Enable (WPIO). When set to Enabled, posting of WC transactions
to PCI occur, even if the I/O bridge has been granted access to
the PCI bus via corresponding arbitration and buffer management
protocol. USWC Write posting should only be enabled if a USWC
region is located on the PCI bus. The settings are: Auto, Dis-
abled or Enabled.

are: Disabled or Enabled.

Master Lat. Timer

Master Latency Timer is an 8-bit register that controls the amount
of time the PAC, as a PCI bus master, can burst data on the PCI
bus. The count value is an 8 bit quantity. However, MLT[2:0] are
0 when determining the count value. The PAC's MLT is used to
guarantee to the PCI agents (other than PAC) a minimum amount
of the system resources. Note: Settings are in increments with an

Optimal and Fail-Safe default setting of 40H.

MTT

Multi-Transaction Timer is an 8-bit register that controls the
amount of time that the PAC's arbiter allows a PCI initiator to

Mode option. The settings are Disabled and 1 Min through 15 Min
in 1 minute intervals.

Standby/Suspend Timer Unit

This allows you to set the standby time out and suspend time out
timer unit. The settings are 32 secs, 4 msecs, 4 min or 4 secs.

Standby Time Out

This option specifies the length of a period of system inactivity
while in full power on state. When this length of time expires, the
computer enters standby power state. The settings are Disabled
and 4 Min through 508 Min in 4 minute intervals.

Suspend Timeout (Minutes)

This option specifies the length of a period of system inactivity
while in standby state. When this length of time expires, the
computer enters suspend power state. The settings are Disabled
and 4 Min through 508 Min in 4 minute intervals.

There is no fail-safe setting for Hour and Minute.

5-1-5 PCI/PnP Setup

Plug and Play-Aware OS

The settings for this option are Yes or No. Set this option to Yes
if the operating system in the computer is aware of and follows
the Plug and Play specification. AMIBIOS only detects and en­ables PnP ISA adapter cards that are required for system boot.
Currently, only Windows 95 is PnP-Aware. Set this option to No if
the operating system (such as DOS, OS/2, Windows 3.x) does not
use PnP. You must set this option correctly. Otherwise, PnP­aware adapter cards installed in the computer will not be config­ured properly.

PCI Latency Timer (PCI Clocks)

This option specifies the latency timings in PCI clocks for all PCI
devices. The settings are 32, 64, 96, 128, 160, 192, 224, or 248.

PCI VGA Palette Snoop

The settings for this option are Disabled or Enabled. When set to
Enabled, multiple VGA devices operating on different buses can

handle data from the CPU on each set of palette registers on
every video device. Bit 5 of the command register in the PCI
device configuration space is the VGA Palette Snoop bit (0 is
disabled). For example: if there are two VGA devices in the
computer (one PCI and one ISA) and this option is disabled, data
read and written by the CPU is only directed to the PCI VGA
device's palette registers. If enabled, data read and written by the
CPU is directed to both the PCI VGA device's palette registers and
the ISA VGA palette registers. This will permit the palette regis-

5-15

BIOS User's Manual

ters of both devices to be identical. This option must be set to
Enabled if any ISA adapter card installed in the system requires
VGA palette snooping.

PCI IDE Busmaster

The settings are: Disabled or Enabled.

Offboard PCI IDE Card

This option specifies if an offboard PCI IDE controller adapter
card is installed in the computer. The PCI expansion slot on the
motherboard where the offboard PCI IDE controller is installed
must be specified. If an offboard PCI IDE controller is used, the
onboard IDE controller is automatically disabled. The settings are
Auto (AMIBIOS automatically determines where the offboard PCI
IDE controller adapter card is installed), Slot 1, Slot 2, Slot 3, Slot
4, Slot 5 or Slot 6.

This option forces IRQ14 and IRQ15 to a PCI slot on the PCI local
bus. This is necessary to support non-compliant ISA IDE control­ler adapter cards. If an offboard PCI IDE controller adapter card
is installed in the computer, you must also set the Offboard PCI
IDE Primary IRQ and Offboard PCI IDE Secondary IRQ options.

Offboard PCI IDE Primary IRQ
Offboard PCI IDE Secondary IRQ

These options specify the PCI interrupt used by the primary (or
secondary) IDE channel on the offboard PCI IDE controller. The
settings are Disabled, Hardwired, INTA, INTB, INTC, or INTD.

PCI Slot1 IRQ Priority
PCI Slot2 IRQ Priority
PCI Slot3 IRQ Priority
PCI Slot4 IRQ Priority

These options specify the IRQ priority for PCI devices installed in
the PCI expansion slots. The settings are Auto, (IRQ) 3, 4, 5, 7,

8, 10, and 11, in priority order.

Chapter 5: Running Setup

DMA Channel 0
DMA Channel 1
DMA Channel 3
DMA Channel 5
DMA Channel 6
DMA Channel 7

These DMA channels control the data transfers between the I/O
devices and the system memory. The chipset allows the BIOS to
choose which channels to do the job. The settings are PnP or

ISA/EISA.

IRQ3
IRQ4
IRQ5
IRQ7
IRQ9
IRQ10
IRQ11
IRQ12
IRQ14
IRQ15

These options specify which bus the specified IRQ line is used
on and allow you to reserve IRQs for legacy ISA adapter cards. If
more IRQs must be removed from the pool, the end user can use
these options to reserve the IRQ by assigning an ISA/EISA setting
to it. Onboard I/O is configured by AMIBIOS. All IRQs used by
onboard I/O are configured as PCI/PnP.

IRQ14 and 15 will not be available if the onboard PCI IDE is
enabled. If all IRQs are set to ISA/EISA and IRQ14 and 15 are
allocated to the onboard PCI IDE, IRQ 9 will still be available for
PCI and PnP devices. This is because at least one IRQ must be
available for PCI and PnP devices. The settings are PCI/PnP or

ISA/EISA.

Reserved Memory Size

This option specifies the size of the memory area reserved for
legacy ISA adapter cards. The settings are Disabled, 16K, 32K,
or 64K.

BIOS Error Beep Codes

During the POST (Power-On Self-Test) routines, which are per­formed each time the system is powered on, errors may occur.

Non-fatal errors are those which, in most cases, allow the
system to continue the boot-up process. The error messages
normally appear on the screen.

Fatal errors are those which will not allow the system to continue
the boot-up procedure. If a fatal error occurs, you should consult
with your system manufacturer for possible repairs.

These fatal errors are usually communicated through a series of
audible beeps. The numbers on the fatal error list, on the follow­ing page, correspond to the number of beeps for the correspond­ing error. All errors listed, with the exception of #8, are fatal
errors.
