INTRODUCTION

Remark:

Suspend to RAM is a sleep state specified by the ACPI specification. It’s the ideal sleep

state for the Instantly Available PC. In this state over 95% of the PC’s power is shut off
enabling a breakthrough in power savings, and the resume time is only a few seconds.

The XStore Pro IDE Driver enhances memory management by working with the
Windows 95/98 operating system, resulting in higher system performance by
implementing "read-ahead caching after seeking". This is especially effective with
the large block sizes of modern hard disks.

PC-cillin anti-virus software provides a powerful defense against viruses to
protect data integration.

MAINBOARD BIOS SETUP

About the BIOS

The Mainboard BIOS (Basic Input/Output System) acts as the bridge between your
Hardware (CPU, Disk Drives, Video, etc.) and Operating System Software
(Windows 95, OS/2 and so on…) The BIOS Setup (also called CMOS Setup) is
where many hardware configuration options are set and stored. This configuration
information will remain in the BIOS until it is changed, or cleared by removing the
battery for a while then reinstalling it back.

CMOS (Complementary Metal Oxide Semiconductor) refers to the chip in which
the BIOS information is stored.

This mainboard features Award BIOS, which provides an easy to use Setup
program to aid in hardware configuration. In this section we will look at the
various menus and options contained in the Award BIOS Setup Program. This
mainboard also features a “Flash” BIOS. A Flash BIOS can be upgraded via
software, thereby eliminating the need to actually replace the “BIOS Chip” on the
mainboard. Procedures for updating the BIOS follow this section.

The Award BIOS installed in your computer system’s ROM (Read Only Memory)
is a custom version of an industry standard BIOS. This means that it supports Intel
processor in a standard IBM-AT compatible input/output system.

Using Setup

In general, you use the arrow keys to highlight items, press <Enter> to select, use
the PageUp and PageDown keys to change entries, press <F1> for help and press
<Esc> to quit.

Getting Help

Pressing F1 will display a small help window that describes the appropriate keys to
use and the possible selections for the highlighted item. To exit the Help Window
press <Esc>.

MAINBOARD BIOS SETUP

A Final Note about Setup

Not all systems have the same Setup. While the basic look and function of the
Setup program remains the same for all systems, individual motherboard and
chipset combinations require custom configurations. For example, you may find
that your Setup main menu has a different number of entries from the main menu
displayed in this manual. These are simply features not supported (or not user
configurable) on your system.

The final appearance of the Setup program also depends on the Original
Equipment Manufacturer (OEM) who built your system. If your OEM has decided
that certain items should only be available to their technicians, those items may
very well be removed from the Setup program.

First, let’s set the system Date. Use the arrow keys to move to and highlight the
“Date” option. Select the Month by using the PgDn and PgUp keys. This is how
most settings will be configured. Then, move to the day, year and time via the
arrow keys to finish setting the system date and time.

Keep in mind that the system time is set in 24-hour time. With this method, 1PM
is represented as 13:00, 2PM as 14:00 and so on, with 00:00 corresponding to
Midnight.

Pri Master, Pri Slave, Sec Master, Sec Slave - These four options relate to the
(4) IDE hard drives, CD-ROMs or other ATAPI devices that can be controlled via
the on-board IDE controller (review IDE Hard Drives and CD-ROMs in the
Installation Guide). The “Pri Master” setting specifies the first device on the

6

BIOS, Driver & Utility Guide

MAINBOARD BIOS SETUP

primary IDE channel, “Pri Slave” - the second. Sec Master and Sec Slave specify
the devices on the secondary channel.

The first option available is the most important: Type. This is where you will
specify the type of device and how it is represented in the BIOS Setup. If the device
is a hard disk or CD-ROM, generally the Auto option is the best choice for fast and
easy setup of the hard disk parameters. Let’s take a look at the difference between
the Auto, User and Types (1-45) options:

• Auto - This option instructs the BIOS to automatically configure the hard disk
by reading the parameters (cylinders, sectors, etc.) directly from the hard
disk’s firmware. Use this option if you are configuring a new hard drive, or
one that has already been formatted using the Auto option. Keep in mind that a
hard drive is configured using a certain set of parameters, those same
parameters must be used for the life of the drive, unless the drive is re­FDISKed using a different parameter set. (This procedure deletes the old
partition(s) on the drive and creates a new one, using the new parameters).

• User - This option allows you to
manually enter in the parameters of
the hard drive. Generally, this option
would be used only if the hard drive
has already been formatted with a
certain set of parameters, and assured
consistency between the old and new
parameters is desired.

• Types 1-45 - Similar to the User option, these types should only be used if the
exact parameters for the hard drive are already entered as a specific type stored
in the Setup Program. Again, this would only be needed to assure that the
parameters the drive was formatted with and those it is using now, are
identical. For new hard drives, the Auto option is the preferred choice.

Mode - One of Enhanced IDE’s most important features is LBA (Logical Block
Addressing) Mode. This feature allows the use of larger hard drives by providing a
way to bypass the cylinder limitations imposed by many Operating Systems. LBA
Mode is used to extend a hard drive’s useable capacity by “remapping” the
cylinders in a way that is acceptable to these operating systems. For instance, a
hard drive with the parameters of 2100 Cylinders, 16 Heads and 63 Sectors would
be represented by LBA Mode as 525 Cylinders, 64 Heads and 63 Sectors. (Notice

MAINBOARD BIOS SETUP

that the Cylinders have been divided, and the Heads have been multiplied, by a
factor of 4.)

On hard drives smaller in capacity than 528MB, LBA support is not needed. The
option on these devices is ignored, even if enabled. For hard drives greater than
528MB, LBA mode should be enabled. The following rules apply:

• Operating Systems that do not use the FAT file system do not need LBA
Mode, and can use the Normal or Large Modes. Examples would be NetWare
and Unix.

• When configuring a new hard drive greater than 528MB in capacity, always
make sure LBA mode is enabled.

• If you are using a hard drive that is over 528MB in capacity, but was already
formatted without using LBA mode, LBA support will be ignored even if it is
enabled. This assures correct access to the drive’s data.

• SCSI Hard Drives are NOT entered into the Mainboard BIOS Setup in any
way. The hard drive settings in the Standard CMOS Setup are only for drives
connected to the IDE Controller. So, if only SCSI drives were installed, all
these settings would be set to Type: None. SCSI Devices are configured via
the SCSI controller’s BIOS.

Floppy Drives A: and B: - Select the Type for the A: and/or B: floppy drives.
Remember, floppy drive A: is the first drive, hooked to the END of the floppy
ribbon cable. Floppy drive B: is hooked up after the twist. Available settings are
listed below:

None No floppy drive installed
360K, 5.25 in 5-1/4 inch PC-type standard drive; 360 kilobyte capacity

1.2M, 5.25 in 5-1/4 inch AT-type high-density drive; 1.2 megabyte capacity
720K, 3.5 in 3-1/2 inch double-sided drive; 720 kilobyte capacity

1.44M, 3.5 in 3-1/2 inch double-sided drive; 1.44 megabyte capacity

2.88M, 3.5 in 3-1/2 inch double-sided drive; 2.88 megabyte capacity

Floppy 3 Mode Support: - Enable this option ONLY for floppy drive(s) that
support the Japanese standard (1.2MB on 3.5” Diskette). Options: Disabled
(Default), Both, Drive A / B.

Anti-Virus Protection – Enables/Disables the built-in anti-virus for protection
against boot virus infection. Unlike traditional BIOS protection which generally
consists of simply write protecting the hard disk partition table, this Anti-Virus
protection provides more complete virus protection by taking control early in the
boot process, detecting boot viruses before they have a chance to load.

MAINBOARD BIOS SETUP

Quick Power on Self Test - Speeds up Power On Self Test (POST) after the
computer is powered on. When set to Enabled, the BIOS will shorten or skip some
checks during POST.

Boot Sequence - When your system is powered on, the BIOS performs a variety of
operations, then attempts to boot an Operating System from either a hard drive
(IDE or SCSI), floppy drive, CD-ROM or LS-120/ZIP. This setting determines the
sequence that the BIOS will follow when searching devices for a bootable disk.

Most users find the C, A, SCSI setting to be most beneficial, since it takes the least
amount of time to boot the system. If however, you want the ability to boot from a
Floppy or CD-ROM drive, you would need to choose either the A, C, SCSI or
CDROM, C, A setting. For instance, if your boot sequence was set to C, A, SCSI
and for some reason you wanted to boot to your Floppy A: Drive, it would not be
possible, since the BIOS would always boot from the C: drive first. In this case,
this setting would need to be changed to A, C, SCSI so that the system would first
check the floppy drive for a bootable disk. This would slow bootup speed, however,
since the floppy would be checked on every boot.

Swap Floppy Drive - The hardware connections determine which floppy is
configured as drive A: and drive B: “Swapping” the floppy drives can be useful if
your system has two floppy drives, and you want the ability to boot from both. For
example: Since a PC cannot boot from the B: Floppy, you would need to “Swap”
floppy drives A: and B: in order to set the second floppy drive to drive A:, thereby
making it bootable.

Boot Up Floppy Seek - When enabled, BIOS will attempt to move the head of the
floppy disk drive forth and back once during POST to see if the drive is working
properly.

Boot Up NumLock Status - When On, the NumLock key will be automatically
enabled when the system boots.

Gate A20 Option - This entry allows you to select how the gate A20 is handled.
The gate A20 is a device used to address memory above 1 Mbytes. Initially, the
gate A20 was handled via a pin on the keyboard (Normal). Today, while keyboards
still provide this support, it is more common, and much faster, for the system
chipset (Fast; default) to provide support for gate A20.

MAINBOARD BIOS SETUP

Typematic Rate Setting - Determines if the typematic rate is to be used. When
disabled, continually holding down a key on your keyboard will generate only one
instance. In other words, the BIOS will only report that the key is down. When the
typematic rate is enabled, the BIOS will report as before, but it will then wait a
moment, and, if the key is still down, it will begin to report that the key has been
depressed repeatedly. This feature is used to accelerate cursor movements with the
arrow keys.

Typematic Rate (Chars/Sec) - When the typematic rate is enabled, this selection
allows you to select the rate at which the keys are accelerated: Options are 6
(default), 8, 10, 12, 15, 20, 24 and 30.

Typematic Delay (Msec) - When the typematic rate is enabled, this selection
allows you to select the delay (in msec) between when the key was first depressed
and when the acceleration begins. Options are 250 (default), 500, 750 and 1000.

Security Option - This option enables password checking every time the computer
is powered on or every time BIOS Setup is executed. If System is chosen, a user
password prompt appears every time the computer is turned on. If Setup is chosen,
the password prompt appears only when the BIOS Setup program is executed.
Refer to the section Supervisor Password for more information.

PCI / VGA Palette Snoop - This option must be set to Enabled if any ISA MPEG
card installed requires VGA palette snooping.

OS Select For DRAM > 64MB - This should be set to OS2 if you are running
IBM OS/2 with more than 64MB of RAM in the system. Otherwise, the setting
should be Non-OS2.

HDD S.M.A.R.T. Capability - The default is Disabled. If you are using hard
drives that support S.M.A.R.T., set this field to Enabled. SMART (Self­Monitoring, Analysis and Reporting Technology) is a reliability prediction
technology for ATA/IDE and SCSI drives. The drive will provide sufficient notice
to the system or user to backup data prior to the drive’s failure. SMART is
supported in ATA-3 or later hard drives.

Report No FDD For WIN95 – When no floppy disk drive is installed, set this
option to No to release IRQ6 for passing Win95 logo. This option is irrelevant
under normal operation.

Video BIOS Shadow - This option controls the location of the contents of the
32KB of Video ROM beginning at the C0000h memory location. The settings are:

Enabled The contents of C0000h-C7FFFh are written to the same address in

system memory (RAM) for faster execution.

Disabled The video ROM is not copied to RAM. The contents of the video

ROM cannot be read from or written to cache memory.

C8000-DFFFF Shadow - These options control the location of the contents of the
16KB expansion card ROMs beginning at the specified memory location. If no
adapter ROM is using the named ROM area, this area is made available to the
local bus. Shadowing a ROM reduces the memory available between 640KB and
1024KB by the amount used for this purpose.

Processor Number Feature – This option is available only when a Pentium III
CPU is used. Each Pentium III CPU features a unique identification number.
Enabling this option allows this internal processor number to be accessed.

System BIOS Cacheable - When Enabled, the contents of the F0000h system
memory segment can be cached to the Level-2 cache memory. The contents of the
F0000h memory segment are always copied from the BIOS ROM to system RAM
for faster execution and PCI compliance.

Video BIOS Cacheable - When Enabled, C0000h to C7FFH become cacheable

Video RAM Cacheable - Enabled will cause access to the video RAM addressed
at B0000H to BFFFH to be cacheable and also let the A0000H to AFFFFH to be a
UC memory type.

8 Bit I/O Recovery Time - The recovery time is the length of time, measured in
ISA BUS clocks, that the system will delay after the completion of an input/output
request. This delay takes place because the CPU is operating faster than the
input/output bus. Therefore the CPU must be delayed to allow for the completion of
I/O transfers. This item allows you to determine the recovery time allowed for 8 bit
I/O. Choices are from NA, 1 to 8 ISA BUS clocks.

16 Bit I/O Recovery Time - This item allows you to determine the recovery time
allowed for 16 bit I/O. Choices are from NA, 1 to 4 ISA BUS clocks.

Memory Hole At 15M-16M - In order to improve compatibility, certain space in
memory can be reserved for old style ISA cards that map memory between 15M­16M. Do not enable this feature unless you use the old style ISA card, otherwise
the memory size may be reduced to 15 MB for some O.S.

Passive Release - The PIIX4 provides a programmable Passive Release mechanism
to meet the required master latencies. When enabled, ISA masters may see long
delays in access to any PCI memory, including the main DRAM array.

MAINBOARD BIOS SETUP

PNP/PCI Configuration Setup

The PCI Personal Component Interconnect Bus was developed to address two
important issues: a) How to allow peripheral devices to take the fullest advantage
of the power of Pentium and Pentium Pro chip technology, and b) Provide a
simpler installation process for peripheral devices, such as Network cards, EIDE or
SCSI controllers.

PCI accomplishes these goals with its 32-bit Data path Local Bus design, and
support for Plug & Play. Unlike older expansion bus architectures, PCI provides
peripherals with a direct connection to the CPU and memory. The PCI bus runs at
33Mhz and has a maximum transfer capability of 132MBps. With Plug & Play, the
system BIOS automatically determines hardware resources for new peripherals,
simplifying installation of multiple interface cards.

This Setup Menu provides configuration options for the PCI Bus and its assigned
resources.

SCAM Support - SCAM (SCSI Configured AutoMatically) is the SCSI Plug and

Play protocol supported by Symbios BIOS version 4.X.

Parity - The Symbios host adapters always generate parity, but some SCSI devices

do not. Therefore, you are offered the option of disabling parity checking.

Note: When disabling parity checking, it is also necessary to disable disconnect for

all devices, as parity checking for the reselection phase will not be disabled. If
a device does not supporting parity disconnects, the I/O will never complete
because the reselection phase will halt.

Host SCSI ID - The host adapter SCSI ID should remain on 7 (default), as this

setting gives the adapter the highest priority on the SCSI bus. However, if you
have two adapters on the same SCSI bus, you should give one of them an
unassigned ID to avoid duplication of SCSI IDs.

Scan Order - This option allows you to tell the host adapter BIOS and your device

drivers to scan the SCSI bus from low to high (0 to max) SCSI IDs, or from
high to low (max to 0) SCSI IDs. If you have more than one device on the
SCSI bus, changing the scan order changes the order in which drive letters are
assigned by the system.

Removable Media Support - Determine if the removable media will be used as

BIOS device. A BIOS device here is a device that can be controlled via BIOS
INT 13H, i.e. it does not need a device driver and can be bootable. However,
when used as a BIOS device, the full removability of removable media devices
is not preserved. The following constraints apply:
a) The device can only work as a fixed disk, i.e. media change is not allowed.

Sync Rate (Mega Bytes/sec) - Defines the maximum transfer rate the host adapter
attempts to negotiate. The host adapter and a SCSI device must agree to a rate they
can both handle.

Width (bits) - Sets the maximum data width the host adapter will attempt to
negotiate. The host adapter and a SCSI device must agree to a width they can both
handle. Only those host adapters that support 16 bit data transfers will show this
option as enabled.

Disconnect - SCSI devices have the ability to disconnect from the bus during an
I/O transfer. This option tells the host adapter whether or not to allow a device to
disconnect. Some devices run faster with disconnect enabled (mostly newer
devices), while some run faster with disconnect disabled (mostly older devices).

Read Write I/O Timeout (secs) - This option sets the time the host adapter waits
for a read, write, verify, or seek command to complete before trying the I/O
transfer again. Since this provides a safeguard allowing the system to recover if an
I/O operation fails, it is recommended that you always set the time-out to a value
greater than zero (no time-out).

BUILT-IN SYMBIOS SCSI BIOS

Scan for Device at Boot Time - When there is a device you do not wish to make
available to the system, set this option to No for that device. Also, on a bus with
only a few devices attached, you can speed up boot time by changing this setting to
No for unused SCSI IDs.

Scan for SCSI LUNs - You can set this option to No if you have problems with a
device that responds to all LUNs whether they are occupied or not.

Queue Tags - If your device driver can issue queue tags, this option allows you to
enable or disable the issuing of queue tags during I/O requests.

Format - Low level format the selected device. All information on the drive will be
erased.

Verify – This command is used to detect bad blocks on the chosen disk. With your
confirmation, the bad blocks detected can be reassigned for future operations. This
command is non-destructive, and therefore won’t destroy the data on the drive.

Since some changes only take effect after your system reboots, it is important that
you quit this Configuration utility properly. You should return to the Main Menu
and exit via the Quit option. If you reboot the system without properly exiting the
utility, some changes may not be saved.

Device Drivers

To function properly with different SCSI devices under different operating systems
you’ll need to install device drivers. The device driver information should be
available in your SCSI adapter’s package.

FLASH BIOS PROGRAMMING UTILITY

Updating the Award BIOS Code is made easy with the AWDFLASH Utility found
under the “Utilities” folder of the supplied CD-ROM. Since this mainboard
features FLASH BIOS, it is not necessary to change the actual BIOS chip in order
to upgrade the System BIOS. The user can simply re-program the old BIOS using
the AWDFLASH Utility as follows:

1. First, boot the system with DOS or to “Safe Mode” under Windows 95. If you
are booting DOS from a hard drive or floppy disk, press [F5] when the message
“Starting MS-DOS…” appears on the screen. If you are booting Windows 95,
press the [F8] key, and select the “Safe mode command prompt” option. This
will assure that the system is running in “real mode” with no device drivers
loaded. This is the only correct way to run the AWDFLASH Utility program.

2. There are (2) important files needed to re-program the BIOS. The first is
“AWDFLASH.EXE” which is the FLASH BIOS Programming Utility. The
second file needed is the updated “BIN” file which contains the actual BIOS
code. This file will have the extension [.bin], such as “P598GH.BIN”. Make
sure these files are on the diskette or hard drive in the same directory.

required files exist and typing: AWDFLASH and pressing [ENTER].

5. The program will then ask if you want to backup the old BIOS. This is
recommended in case there are any problems with the new “.bin” file. Enter the
name of the new backup file (such as “backup.bin”) and press [ENTER].

6. At this time the system will prompt you for final confirmation before beginning
programming. The Utility can be aborted at this time by hitting “n”. To begin
programming, hit “y”…

7. When the Flash programming starts, a bar indicator will show the progress of
the programming operation. After successful completion, hit the reset button or
power off the computer.

Be sure to perform “LOAD SETUP DEFAULTS” for your new BIOS to
synchronize the previous BIOS with the updated BIOS.

DMI UTILITY

This mainboard supports the Desktop Management Interface (DMI), which is a
new method of providing enterprise management for personal computers. The
main component of DMI is the Management Information Format Database (MIF),
which contains information about the computer system and its components, such as
BIOS version/vendor, CPU speed/type, memory size/type, L1/L2 cache, port
connectors (IDE, floppy, 2S/1P, USB, keyboard, mouse, ), slots … etc. Using DMI,
remote PC management software is able to obtain various information about the
system, including hardware profiles, capabilities, operational status, installation
dates, and other information about the system and its components.

This DMI utility, DMICFG.EXE found under the “Utilities” folder of the supplied
CD-ROM, allows you to add additional information, such as serial numbers,
vendor information, and enclosure/chassis configurations, into the MIF.
