Introduction

1-2 Chipset Overview

Intel's 810 chipset was developed to bring new features to value PC plat­forms. Integrated audio and graphics eliminate the cost of discrete compo­nents and free up space for additional peripheral cards. These onboard
features are based on the AC'97 2.1 compliant link for audio and telephony
CODECs and the onboard graphics controller chip. The main bridge of the
810 is the Graphics and Memory Controller Hub (GMCH), which enables a
66 or 100 MHz front side bus speed. An I/O Hub Controller (ICH) integrates
PCI peripherals and I/O functions with a dedicated 33 MHz PCI bus. This
hub separates the I/O devices from the GMCH for improved performance.
The 810's accelerated hub interface provides a 266 MB/sec bandwidth be­tween the GMCH and ICH for smoother-streaming video and audio.

Graphics Memory Controller Hub (GMCH)

The GMCH is the host bridge of the 810 chipset and provides the intercon­nect between the SDRAM and the rest of the system logic. It includes a
system memory DRAM controller, which supports a 64-bit 100 MHz DRAM
array, and utilizes Direct AGP (integrated AGP) technology to create vivid
2D and 3D effects and images.

I/O Controller Hub (ICH)

The ICH is the I/O Controller Hub for the I/O subsystem and integrates many
of the functions required by today's PC platforms. It provides the interface
to the PCI Bus and communicates with the GMCH over a dedicated hub
interface. There are two versions of the ICH: the ICH and the ICH0. The
370SWD and 370SWT have the ICH version, which supports ATA66. The
370SWM has the ICH0, which supports ATA33.

Audio Modem Riser (AMR)

The AMR is a new modular specification that integrates the audio/modem
functions on the motherboard by assigning the analog I/O functions to a
riser card. Integration of the audio/modem function enhances system capa­bilities while reducing costs. The AMR interface is based on an AC-link that

is compliant with Intel’s Audio Codec ’97 version 2.1 specification.

Firmware Hub (FWH)

The FWH is a component that brings added security and managability to the
PC platform infrastructure. This device includes an integrated Random Num­ber Generator (RNG) to enable stronger encryption, digital signing and se­curity protocols. The FWW stores the system BIOS and video BIOS, which
eliminates a redundant nonvolatile memory component.

Suspend to RAM (STR)

When the system goes into a deep sleep (S3) state, power is removed from
most of the system components but remains supplied to RAM to quickly
restore the system to its previous state of operation. Because system
restoration happens in only ~5 seconds, applications that were open before
the sleep state can be reopened 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 1-19 for details on
initiating ACPI. All drivers and add-on cards must be ACPI supported for
STR to function.

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 Loss Control setting in BIOS on page 4-20 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
370SWD/370SWT/370SWM . All have an onboard System Hardware Moni­tor chip that supports PC health monitoring.

the sensitivity of the voltage monitor.

Three-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 manage­ment 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
settings in BIOS (see page 4-18). These settings allow the user to enable
a warning and define the overheat temperature. When this temperature is
exceeded, both the overheat fan and the warning LED are triggered.

System Resource Alert

This feature is available when used with the Super Doctor utility program. It
is used to notify the user of certain system events, such as a user-defined
CPU temperature being exceeded, voltages sensed as being too high or too

Introduction

low, fan failure and chassis intrusion. (Utilizing chassis intrusion requires
a microswitch to be attached between the chassis and the JL1 header on
the motherboard.)

Chassis Intrusion Detection

The chassis intrusion circuitry can detect unauthorized intrusion to the sys­tem. The chassis intrusion connector is located on JL1. Attach a
microswitch to JL1. When the microswitch 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 turned on. This feature is available
when the user is running SUPERMICRO's Super Doctor utility.

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 pro­vides a standard way to integrate power management features throughout
a PC system, including its hardware, operating system and application soft­ware. 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, tele­phones 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 Windows

Introduction

98. Note: 1. Windows NT 4.0 does not support ACPI. 2. To install 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 re­quests.

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

Introduction

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 370SWD/370SWT/370SWM accommodates ATX power supplies.
Although most power supplies generally meet the specifications required by
the CPU, some are inadequate.

It is highly recommended that you use a high quality power supply that
meets ATX power supply Specification 2.01. 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.

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.

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 re­motely power up a computer that is powered off. Remote PC setup, up­dates 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. Note
that Wake-On-Lan can only be used with an ATX 2.01 (or above) compliant
power supply.

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 generator, 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 components 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). Extension FDD and Extension 2FDD Modes are also available
through the printer port interface pins to allow one or two external floppy
disk drives to be connected.

The Super I/O provides functions that comply with ACPI (Advanced Con­figuration and Power Interface), which includes support of legacy and ACPI
power management through an SMI or SCI function pin. It also features
auto power management 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 370SWD/370SWT/370SWM Manual

Installation

Heat Sink

Follow the instructions that came with your processor or heat sink to attach
a heat sink to the processor. Make sure that good contact is made between
the CPU chip and the heat sink.

Processor

You are now ready to install the processor. Your motherboard has a 370-pin,
PPGA type socket, which supports 370-pin (not SEPP type) Celeron processors.
Lift the lever on the PPGA socket and install with the notched corner of the
processor oriented with pin 1. Fully seat the processor into the socket and then
close the lever. See Figure 2-1 for views of the PPGA 370-pin socket before and
after processor installation.

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 elimi­nate 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.

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.

2-9 Installing Software Drivers

After all the hardware has been installed you must install the software drivers.
The necessary drivers are all included on the Supermicro CD that came packaged
with your motherboard. After inserting this CD into your CDROM drive, the
display shown in Figure 2-5 should appear. (If this display does not appear, click
on the My Computer icon and then on the icon representing your CDROM drive.
Finally, double click on the S "Setup" icon.)

Figure 2-5. Driver/Tool Installation Display Screen

Click the icons showing a hand writing on paper to view the readme files for each
item. Click the tabs to the right of these

in order from top to bottom

to install
each item one at a time. After installing each item, you must reboot the
system before moving on to the next item on the list. You should install
everything here except for the SUPER Doctor utility, which is optional. The
Security and Graphics Drivers support multiple languages. Click the arrows to
pull down a menu of choices. The CD icon at the bottom allows you to view the
entire contents of the CD.

3-1 Troubleshooting Procedures

Use the following procedures to troubleshoot your system. If you have followed
all of the procedures below and still need assistance, refer to the ‘Technical
Support Procedures’ and/or ‘Returning Merchandise for Service’ section(s) in this
chapter. Note: Always disconnect the power cord before adding, changing

or installing any hardware components.

Before Power On

1. Make sure no short circuits exist between the motherboard and chassis.

2. Disconnect all ribbon/wire cables from the motherboard, including those for

the keyboard and mouse.

3. Remove all add-on cards.

4. Install a CPU (making sure it is fully seated), the chassis speaker and the

power LED to the motherboard. (Check all jumper settings as well.)

5. Install a single memory module and make sure it is fully seated.

6. Check the power supply voltage 115V/230V switch.

No Power

1. Make sure no short circuits exist between the motherboard and chassis.

2. Verify that all jumpers are set to their default positions.

3. Turn the power switch on and off to test the system.

4. Check that the 115V/230V switch on the power supply is properly set.

5. Your battery may be old. Check that it still supplies ~3VDC. If not,

replace it with a new one.

No Video

1. If the power is on but you have no video, remove all the add-on cards and

cables.

2. Set JP14 ON to enable the CPU Safe Mode and set all other jumpers to

their default settings. (Default settings are listed in the Quick Reference
sections across from the motherboard layout.) Check the CPU clock
speed to make sure it's correct (see page 2-10 for details).

3. Use the speaker to determine if any beep codes exist. Refer to Appendix

A for details on beep codes.

3-2

SUPER 370SWD/370SWT/370SWM Manual

Troubleshooting

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 1-20 for
details.

2. Your battery may be old. Check that it still supplies ~3VDC. If not,
replace with a new one.

3. If the above steps do not fix the Setup Configuration problem, contact your
vendor for repair.

3-2 Technical Support Procedures

Before contacting Technical Support, please take the following steps. Also, note
that as a motherboard manufacturer, Super Micro does not sell directly to end­users, so it is best to first check with your distributor or reseller for troubleshoot­ing services. They should know of any possible problem(s) with the specific
system configuration that was sold to you.

1. Please go through the ‘Troubleshooting Procedures’ and 'Frequently Asked
Question' (FAQ) sections in this chapter or see the FAQs on our web site
(http://www.supermicro.com/techsupport.htm) before contacting Technical
Support.

2. BIOS upgrades can be downloaded from our web site at
http://www.supermicro.com/techsupport/download.htm.

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.

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 PC 100 compliant, unbuffered SDRAM. EDO,
buffered and registered SDRAM are not supported.

4. Check for bad DIMM modules or slots by swapping a single DIMM module
between both DIMM slots and noting the results.

3-3

Chapter 3: Troubleshooting

Troubleshooting

Note: Not all BIOS can be flashed depending on the modifica­tions to the boot block code.

3. If you still cannot resolve the problem, include the following information
when contacting Super Micro for technical support:

• Motherboard model and PCB revision number

•BIOS release date/version
(this can be seen on the initial display when your system first boots up)

•System configuration
An example of a Technical Support Form is on our web site at
http://www.supermicro.com/techsupport/contact_support.htm.

4. Distributors: For immediate assistance, please have your account number
ready when placing a call to our technical support department. We can be
reached by e-mail at [e-mail] or by fax at [phone].

3-3 Frequently Asked Questions

Question: What are the various memories that the 810 motherboard can
support?

Answer: Your motherboard has two DIMM sockets that support 168-pin, unbuf-

fered 3.3V SDRAM. It does not support registered, ECC or EDO memory. Note
that whether running at 66 or 100 MHz FSB speed, the memory must be PC100
compliant. Because ECC is not supported, using ECC memory will result in non­ECC operation.

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 on
our web site at http://www.supermicro.com. Please check our BIOS 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 your BIOS before
downloading. Select your motherboard model and download 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 command "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.

3-4

SUPER 370SWD/370SWT/370SWM Manual

Troubleshooting

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 the JPWAKE jumper 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 included on the CD are PCI IDE
Bus Master drivers for Windows 98 and Windows NT, 810 chipset drivers for
Windows 98, graphics and sound drivers and Super Doctor Monitoring software.

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 (see page 4-12). When the On/Off feature is enabled, the mother­board 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. This feature is required to implement the ACPI
features on the motherboard.

Question: I see some of my PCI devices sharing IRQs, but the sys­tem 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 shar­ing IRQs. See Table 3-1 below for details on shared IRQs.

Question: I successfully installed the audio driver for my onboard
audio, but can barely hear the sound from my speakers. What's
the problem?

Answer: (1) This may be due to a software setting. In Windows, go to

<Start>, <Settings>, <Control Panel>, <Multimedia> and finally <CD Music>.
Check the box beside the line that reads "Enable digital CD audio for this
CD-ROM drive". (2) If the previous step does not work, your speaker may
require an amplifier to function. If you are playing music from an external
audio CDROM, you must connect an audio cable (not included) from your CD
unit to either the CD or CD_1 header on the motherboard. See page 2-9 for
details.

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

(370SWD/370SWT only) has two connectors to support two drives. This
special cable must be used to take advantage of the speed the ATA66
technology offers. Connect 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 the Intel 810 PPGA Celeron 333-500
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.

Entering Drive Parameters

You can also enter the hard disk drive parameters. The drive parameters are:

Parameter Description

Type The number for a drive with certain identification parameters.

Cylinders The number of cylinders in the disk drive.

Heads The number of heads.

Write The size of a sector gets progressively smaller as the track

Precompensation 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)

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

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.
