Chapter 1: Introduction
1-2 Chipset Overview
Intel’s 840 chipset is based on the new modular design introduced by the
800 series chipsets and consisting of three main components. The 82840
Memory Controller Hub (MCH) provides support for AGP2x/4x and AGP Pro.
An 82801 I/O Controller Hub (ICH) connects the PCI slots, IDE controllers
and USB ports to the MCH via an accelerated hub architecture. The third
main component is the 82802 Firmware Hub (FWH), which stores both sys-
tem and video BIOS and includes a Random Number Generator (RNG).
Memory Controller Hub (MCH)
The MCH includes the host (CPU) interface, DRAM interface, ICH interface,
4xAGP interface and P64 interface for the 840 chipset. It contains ad-
vanced power management logic and supports dual channels for DRAM.
The AGP 2.0 interface supports 4x data transfer and 2x/4x fast write capa-
bility and operates at a peak bandwidth of 266 MB/sec. The MCH host
interface bus runs at 133/100 MHz.
I/O Controller Hub (ICH)
The ICH is the Controller Hub for the I/O subsystem and integrates many of
the Input/Output functions of the 840 chipset, including a two-channel
UDMA/66 Bus Master IDE controller. It also provides the interface to the PCI
Bus and communicates with the MCH over a dedicated hub interface.
Firmware Hub (FWH)
The FWH is a component that brings added security and manageability to
the PC platform infrastructure. This device includes an integrated Random
Number Generator (RNG) for stronger encryption, digital signing and secu-
rity protocols. The FWH stores the system BIOS and video BIOS to eliminate
a redundant nonvolatile memory component.
PCI 64-bit Hub (P64H)
The P64H chip provides a bridge between the MCH and the PCI Bus. It has
a 16-bit primary hub interface to the MCH and a secondary 64-bit PCI Bus
interface, which supports both 64-bit and 32-bit PCI devices. The P64H is
PCI 2.2 compliant.

SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME User's Manual
Suspend to RAM (STR)
When the system goes into a sleep state, power is removed from most of
the system components but can remain supplied to RAM to quickly restore
the system to its previous state of operation. Because system restoral
happens in only ~5 seconds, applications that were open before the sleep
state can reopen for immediate access. In STR, all data in system memory
is stored in RAM when the system is suspended and system power is
turned off (the power supply fan also shuts off). You must be running
ACPI for this feature to take effect. See page 1-22 for details on initiating
ACPI. All drivers and add-on cards must be ACPI supported for STR to
function.
Alert on LAN 2 (AOL2)
AOL2 ASIC brings an advanced level of management interface between a
remote management console/server and the client system. It provides inter-
faces to the 82559 Ethernet controller chip and to system monitoring de-
vices. AOL2 can send "Alert" messages to the mangagement console to
notify administrators of important events or problems such as high tempera-
tures, chassis intrusion and voltages exceeding safe margins.
Recovery from AC Power Loss
BIOS provides a setting for you to determine how the system will respond
when AC power is lost and then restored to the system. You can choose
for the system to remain powered off (in which case you must hit the
power switch to turn it back on) or for it to automatically return to a power
on state. See the Power Lost Control setting in BIOS on page 4-11 of this
manual to change this setting. The default setting is Always OFF.
1-3 PC Health Monitoring
This section describes the PC health monitoring features of the SUPER
PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME. All have an onboard System Hardware Moni-
tor chip that supports PC health monitoring.

Chapter 1: Introduction
Seven Onboard Voltage Monitors for the CPU Core, Chipset
Voltage, +3.3V, ±5V and ±12V
The onboard voltage monitor will scan these seven voltages continuously.
Once a voltage becomes unstable, it will give a warning or send an error
message to the screen. Users can adjust the voltage thresholds to define
the sensitivity of the voltage monitor.
Four-Fan Status Monitor with Firmware/Software On/Off
Control
The PC health monitor can check the RPM status of the cooling fans. The
onboard 3-pin CPU and chassis fans are controlled by the power manage-
ment functions. The thermal fan is controlled by the overheat detection
logic.
Environmental Temperature Control
The thermal control sensor monitors the CPU temperature in real time and
will turn on the thermal control fan whenever the CPU temperature exceeds
a user-defined threshold. The overheat circuitry runs independently from
the CPU. It can continue to monitor for overheat conditions even when the
CPU is in sleep mode. Once it detects that the CPU temperature is too high,
it will automatically turn on the thermal control fan to prevent any overheat
damage to the CPU. The onboard 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 activates when the power is turned on. It can be turned off
when the CPU is in sleep mode. When in sleep mode, the CPU will not run
at full power, thereby generating less heat.
CPU Overheat LED and Control
This feature is available when the user enables the CPU overheat warning
function in the BIOS (see page 4-17). This allows the user to define an
overheat temperature. When this temperature is exceeded, both the over-
heat fan and the warning LED are triggered.

SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME User's Manual
System Resource Alert
This feature is available when used with Intel's LANDesk Client Manager
(optional). It is used to notify the user of certain system events. For
example, if the system is running low on virtual memory and there is insuf-
ficient hard drive space for saving the data, you can be alerted of the
potential problem.
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 can prevent viruses from
infecting the BIOS area and destroying valuable data.
Auto-Switching Voltage Regulator for the CPU Core
The auto-switching voltage regulator for the CPU core can support up to
20A current and auto-sense voltage IDs ranging from 1.3V to 3.5V. This
will allow the regulator to run cooler and thus make the system more stable.
1-4 ACPI/PC 98 Features
ACPI stands for Advanced Configuration and Power Interface. The ACPI
specification defines a flexible and abstract hardware interface that pro-
vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft-
ware. This enables the system to automatically turn on and off peripherals
such as CD-ROMs, network cards, hard disk drives and printers. This also
includes consumer devices connected to the PC such as VCRs, TVs, tele-
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 oper-
ating system-independent interface for configuration control. ACPI lever-
ages the Plug and Play BIOS data structures while providing a processor
architecture-independent implementation that is compatible with both Win-
dows 98 and Windows NT 5.0. Note: To utilize ACPI, you must reinstall
Windows 98. To reinstall Windows 98 with ACPI, enter DOS and type
"setup /p J" at the CDROM prompt (usually D:\) with the Windows 98 CD
loaded. (Make sure you include the spaces after "setup" and "p".) Then hit
<Enter>. You can check to see if ACPI has been properly installed by

looking for it in the Device Manager, which is located in the Control Panel in
Windows.
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 to be off and responds immediately to user or other re-
quests.
Slow Blinking LED for Suspend-State Indicator
When the CPU goes into a suspend state, the chassis power LED will start
blinking to indicate that the CPU is in suspend 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.
Real Time Clock Wake-Up Alarm
Although the PC may be perceived to be off when not in use, it is still
capable of responding to preset wake-up events. In the BIOS, the user can
set a timer to wake-up the system at a predetermined time (see page 4-14)
Main Switch Override Mechanism
When an ATX power supply is used, the power button can function as a
system suspend button. When the user depresses the power button, the
system will enter a SoftOff state. The monitor will be suspended and the
hard drive will spin down. Depressing 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 in the system alive. In
case the system malfunctions and you want to turn off the power, just
depress and hold the power button for 4 seconds. The power will turn off
and no power will be provided to the motherboard.

SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME User's Manual
External Modem Ring-On
Wake-up events can be triggered by a device such as the external modem
ringing when the system is in the SoftOff state. Note that external modem
ring-on can only be used with an ATX 2.01 (or above) compliant power
supply.
Wake-On-LAN (WOL)
Wake-On-LAN is defined as the ability of a management application to re-
motely power up a computer that is powered off. Remote PC setup, up-
dates and asset tracking can occur after hours and on weekends so that
daily LAN traffic is kept to a minimum and users are not interrupted. The
motherboards have a 3-pin header (WOL) to connect to the 3-pin header on
a Network Interface Card (NIC) that has WOL capability. Wake-On-LAN
must be enabled in BIOS. Note that Wake-On-Lan can only be used with an
ATX 2.01 (or above) compliant power supply.
1-5 Power Supply
As with all computer products, a stable power source is necessary for
proper and reliable operation. It is even more important for processors that
have high CPU clock rates of 300 MHz and above.
The SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME accommodates ATX power sup-
plies. Although most power supplies generally meet the specifications re-
quired by the CPU, some are inadequate.
It is strongly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.01 or above. Additionally, in areas
where noisy power transmission is present, you may choose to install a
line filter to shield the computer from noise. It is recommended that you also
install a power surge protector to help avoid problems caused by power
surges.
Note: To support the keyboard wake-up function, your power supply must
be ATX 2.01 or higher and must provide a minimum standby voltage of 720
mA.

Chapter 1: Introduction
1-6 Super I/O
The disk drive adapter functions of the Super I/O chip include a floppy disk drive
controller that is compatible with industry standard 82077/765, a data separator,
write pre-compensation circuitry, decode logic, data rate selection, a clock gen-
erator, drive interface control logic and interrupt and DMA logic. The wide range
of functions integrated onto the Super I/O greatly reduces the number of compo-
nents required for interfacing with floppy disk drives. The Super I/O supports four
360 K, 720 K, 1.2 M, 1.44 M or 2.88 M disk drives and data transfer rates of 250
Kb/s, 500 Kb/s or 1 Mb/s.
It also provides two high-speed, 16550 compatible serial communication ports
(UARTs), one of which supports serial infrared communication. Each UART
includes a 16-byte send/receive FIFO, a programmable baud rate generator,
complete modem control capability and a processor interrupt system. Both
UARTs provide legacy speed with baud rate of up to 115.2 Kbps as well as an
advanced speed with baud rates of 250 K, 500 K, or 1 Mb/s, which support higher
speed modems.
The Super I/O supports one PC-compatible printer port (SPP), Bi-directional
Printer Port (BPP) , Enhanced Parallel Port (EPP) or Extended Capabilities Port
(ECP).
The Super I/O provides functions that comply with ACPI (Advanced Configuration
and Power Interface), which includes support of legacy and ACPI power manage-
ment through an SMI or SCI function pin. It also features auto power manage-
ment to reduce power consumption.
The IRQs, DMAs and I/O space resources of the Super I/O can flexibly adjust to
meet ISA PnP requirements, which suppport ACPI and APM (Advanced Power
Management).

2-1 Static-Sensitive Devices
Static-sensitive electrical 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 to prevent static discharge.
Touch a grounded metal object before removing the board from the antistatic
bag.
•
Handle the board by its edges only; do not touch its components, peripheral
chips, memory modules or gold contacts.
•
•
When handling chips or modules, avoid touching their pins.
Put the motherboard and peripherals back into their antistatic bags when not
in use.
•
For grounding purposes, make sure your computer chassis provides excellent
conductivity between the power supply, the case, the mounting fasteners and
the motherboard.
Unpacking
The motherboard is shipped in antistatic packaging to avoid static damage.
When unpacking the board, make sure the person handling it is static protected.

SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME User's Manual
2-2 Processor Installation
When handling the processor package, avoid placing
direct pressure on the label area of the fan.
!
The following pages cover the installation procedure. You should install the
processor to the motherboard first, then install the motherboard in the chassis,
then the memory and add-on cards, and finally the cables and drivers. Following
the installation procedures in the order they appear in this chapter should elimi-
nate the most common problems encountered when installing a system.
IMPORTANT: Always connect the power cord last and always remove it
before adding, removing or changing any hardware components.
Heat Sink
Follow the instructions that came with your processor or heat sink to
attach a heat sink to the processor. Your heat sink should have a 3-pin
fan, which connects to the CPU 1/2 header. Make sure that good contact
is made between the CPU cartridge and the heat sink, particularly with
SECC2 Pentium III OEM packages. Insufficient contact will cause the
processor to overheat, which may crash the system.
URM
Your motherboard has a preinstalled URM (Universal Retention Mecha-
nism). A picture of a URM is shown in Figure 2-1. (This is one of
several types - all of which can support SEPP, SECC and SECC2 pack-
ages.) Before installing your processor, you must flip the arms of the
URM to their upright positions. Some URMs may have extra caps to be
used for Pentium III processors (AMP URMs do not use these). After the
processor is installed in the motherboard, place one of these caps (if
included) on each end of the URM and push down until they snap into
place. These caps are not left/right specific.
Processor
You are now ready to install the processor. Your motherboard has a Slot
1 type connector, which supports Celeron, Pentium II* and Pentium III pro-
cessors housed in SEPP, SECC* and SECC2 packages, respectively. Please
see the note on the following page when installing a Pentium II processor
with the SECC package.

Chapter 2: Installation
*Note: The Pentium II processor comes in the SECC package, which has
locking tabs on the top corners. Before installing the Pentium II package into
the URM, push these two locks inward until you hear a click. (After you
have fully seated the processor into the Slot 1 connector as instructed
below, these locks should return to their outer positions.)
Arm (in upright
position)
Figure 2-1. Universal Retention Mechanism (URM)
With the heat sink facing toward the DIMM memory slots, slide the SEPP/
SECC/SECC2 processor package into the URM and continue pushing it down
until fully seated in the Slot 1 connector. Some URMs have extra caps to be
used for SECC2 processors (AMP URMs do not have these). If so, after the
processor is installed in the motherboard, place a cap on each end of the
URM and push down until they snap into place. These caps are not left/
right specific.
2-3 Mounting the Motherboard in the Chassis
All motherboards have standard mounting holes to fit different types of chassis.
Chassis may include a variety of mounting fasteners made of metal or plastic.
Although a chassis may have both types, metal fasteners are the most highly
recommended because they ground the motherboard to the chassis. For this
reason, it is best to use as many metal fasteners as possible.

2-4 Installing DIMMs
CAUTION
Exercise extreme care when installing or removing DIMM
modules to prevent any possible damage.
DIMM Installation (See Figure 2-2)
1. Insert DIMMs as required for the desired system memory. Note that the
PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME interleaves memory for increased
performance, which requires you to install two modules at a time.
2. Insert each DIMM module vertically into its slot. Pay attention to the
two notches along the bottom of the module to prevent inserting the
DIMM module incorrectly.
3. Gently press down on the DIMM module until it snaps into place in the
slot. As stated in 1 above, you must populate either two or four
banks of memory.
Support
The PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME supports registered DIMMs and ECC
type memory. PC133 and PC100 memory are both supported but will
result in the same perfomance, as the memory bus runs at 100 MHz.

•
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 twisted wires
always connects to drive B.
•
The 80-wire ATA66 IDE hard disk drive cable that came with your system has
two connectors to support two drives. This special cable should be used to
take advantage of the speed this new technology offers. The blue connector
connects to the onboard IDE header and the other connector(s) to your hard
drive(s). Consult the documentation that came with your disk drive for details
on actual jumper locations and settings.

AGP Pro Slot
The AGP Pro slot is backward compatible with AGP and 4xAGP graphics
cards, which have fewer pins than AGP Pro cards. Because of this,
care must be taken when installing a graphics card into this slot, as doing
so incorrectly can damage your motherboard. For AGP Pro cards, you
should remove the orange sticker covering one end of the slot. For other
cards, leave this sticker in place and make sure your card does not plug
into the section it covers. A general rule of thumb is to make sure your
card fills the center section of pins first, then the end toward the edge of
the motherboard if there are more. If the I/O shield of your card is flush
with the edge of the motherboard, the card should be inserted correctly.

NOTE
If you are a system integrator, VAR or OEM, a POST diagnostics
card is recommended. For I/O port 80h codes, refer to App. B.
Memory Errors
1. Make sure the DIMM modules are properly and fully installed. Inter-
leaved memory requires that modules must be installed in pairs (two
slots at a time).
2. Determine if different speeds of DIMMs have been installed and verify
that the BIOS setup is configured for the fastest speed of RAM used.
It is recommended to use the same RAM speed for all DIMMs in the
system.
3. Make sure you are using PC133 or PC100 compliant, unbuffered
SDRAM. EDO SDRAM is not supported.
4. Check for bad DIMM modules or slots by swapping a single module
between both slots and noting the results.
5. Make sure all memory modules are fully seated in their slots.
6. Check the power supply voltage 115V/230V switch.
Losing the System’s Setup Configuration
1. Check the setting of jumper JBT1. Ensure that you are using a high
quality power supply. A poor quality power supply may cause the
system to lose the CMOS setup information. Refer to page 1-24 for
details on recommended power supplies.
2. The battery on your motherboard may be old. Check to verify that it
still supplies ~3VDC. If it does not, replace it with a new one.
3. If the above steps do not fix the Setup Configuration problem, contact your
vendor for repairs.

3-3 Frequently Asked Questions
Question: What are the various types of memory that the PIIIDM6/
PIIIDM4/PIIIDM3/PIIIDME motherboard can support?
Answer: The PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME has four DIMM slots that sup-
port 168-pin, unbuffered 3.3V SDRAM. ECC memory is also supported.
Note that while both PC133 and PC100 memory are supported, they will
offer the same performance since the 840 chipset has a 100 MHz memory
bus. Check the Memory ECC Mode in BIOS to enable the use of ECC.
Modules must be installed in pairs (two slots at a time) because interleaved
memory technology is used.
Question: How do I update my BIOS?
Answer: It is recommended that you do not upgrade your BIOS if you are
experiencing no problems with your system. Updated BIOS files are located
warning message and the info on how to update your BIOS on our web
site. Also, check the current BIOS revision and make sure it is newer than
3-3
Download from Www.Somanuals.com. All Manuals Search And Download.
SUPER PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME User's Manual
your BIOS before downloading. Select your motherboard model and down-
load the BIOS file to your computer. Unzip the BIOS update file and you will
find the readme.txt (flash instructions), the fwhflash.com (BIOS flash utility)
and the BIOS image (xxxxxx.rom) files. Copy these files onto a bootable
floppy and reboot your system. It is not necessary to set BIOS boot block
protection jumpers on the motherboard. At the DOS prompt, enter the com-
mand "fwhflash." This will start the flash utility and give you an opportunity
to save your current BIOS image. Flash the boot block and enter the name
of the update BIOS image file.
Note: It is important to save your current BIOS and rename 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 Optimal Values in the BIOS.
Question: After flashing the BIOS my system does not have video.
How can I correct this?
Answer: If the system does not have video after flashing your new BIOS, it
indicates that the flashing procedure failed. To remedy this, first clear CMOS per
the instructions in this manual and retry the BIOS flashing procedure. If you still
do not have video, please use the following BIOS Recovery Procedure. First,
make sure jumper JP6 is disabled. Then, turn your system off and place the
floppy disk with the saved BIOS image file (see above FAQ) in drive A.
Press and hold <CTRL> and <Home> at the same time, then turn on the
power with these keys pressed until your floppy drive starts reading. Your
screen will remain blank until the BIOS program is done. If the system
reboots correctly, then the recovery was successful. The BIOS Recovery
Procedure will not update the boot block in your BIOS.
Question: Do I need the CD that came with your motherboard?
Answer: The supplied compact disc has quite a few drivers and programs
that will greatly enhance your system. We recommend that you review the
CD and install the applications you need. Applications on the CD include
840 chipset drivers for Windows and security and audio drivers.
Question: Why can't I turn off the power using the momentary
power on/off switch?
Answer: The instant power off function is controlled in BIOS by the Power
Button Mode setting. When the On/Off feature is enabled, the motherboard
3-4
Download from Www.Somanuals.com. All Manuals Search And Download.
Chapter 3: Troubleshooting
will have instant off capabilities as long as the BIOS has control of the
system. When the Standby or Suspend feature is enabled or when the
BIOS is not in control such as during memory count (the first screen that
appears when the system is turned on), the momentary on/off switch must
be held for more than four seconds to shut down the system. This feature
is required to implement the ACPI features on the motherboard.
Question: I see some of my PCI devices sharing IRQs, but the sys-
tem seems to be fine. Is this correct or not?
Answer: Some PCI Bus Mastering devices can share IRQs without perfor-
mance penalties. These devices are designed to work correctly while shar-
ing IRQs. See Table 3-1 below for details on shared IRQs.
Table 3-1. Shared IRQs
PIIIDM6/PIIIDM4/PIIIDM3/PIIIDME
PCI 1 shares an IRQ with the NIC and the AGP Pro slot
PCI 2 shares an IRQ with the onboard audio and the SM bus*
PCI 3 shares an IRQ with 64-bit PCI slots 1 and 2
PCI 4 shares an IRQ with the USB
*System Management bus
Question: I installed my microphone correctly but I can't record any
sound. What should I do?
Answer: Go to <Start>, <Programs>, <Accessories>, <Entertainment> and
then <Volume Control>. Under the Properties tab, scroll down the list of
devices in the menu and check the box beside "Microphone".
Question: How do I connect the ATA66 cable to my IDE device(s)?
Answer: The 80-wire/40-pin ATA66 IDE cable that came with your system
has two connectors to support two drives. This special cable must be
used to take advantage of the speed the ATA66 technology offers. Con-
nect the blue connector to the onboard IDE header and the other
connector(s) to your hard drive(s). Consult the documentation that came
with your disk drive for details on actual jumper locations and settings.

Chapter 4
BIOS
4-1 Introduction
This chapter describes the AMIBIOS for Intel 840 Pentium II/III 350-733 MHz
processors. The AMI ROM BIOS is stored in a Flash EEPROM and can be
easily upgraded using a floppy disk-based program.
System BIOS
The BIOS is the Basic Input Output System used in all IBM® PC, XT™, AT®,
and PS/2® compatible computers.
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 kbytes of non-volatile memory storage in
CMOS RAM. All AT-compatible systems have at least 64 kbytes of CMOS
RAM, which is usually part of the Real Time Clock. Many systems have 128
kbytes 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.

The number for a drive with certain identification parameters.
The number of cylinders in the disk drive.
The number of heads.
Cylinders
Heads
Write
Precompensation
The size of a sector gets progressively smaller as the track
diameter diminishes. Yet each sector must still hold 512 bytes.
Write precompensation circuitry on the hard disk compensates
for the physical difference in sector size by boosting the write
current for sectors on inner tracks. This parameter is the track
number where write precompensation begins.
Sectors
The number of sectors per track. MFM drives have 17 sectors
per track. RLL drives have 26 sectors per track. ESDI drives
have 34 sectors per track. SCSI and IDE drive may have even
more sectors per track.
Capacity
The formatted capacity of the drive is (Number of heads) x
(Number of cylinders) x (Number of sectors per track) x (512
bytes per sector)
Boot Sector Virus Protection

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, PnP-aware 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 registers 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 for this option are Disabled or Enabled. Set to Enabled to
specify the IDE Controller on the PCI bus has bus mastering capabilities.
Under Windows 95, you should set this option to Disabled and install the
Bus Mastering driver.
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 automati-
cally 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 and 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.

BIOS Error Beep Codes & Messages
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.
