This chapter tells how to configure the system parameters. You may update
your BIOS via AWARD Flash Utility.
Important: Because the BIOS code is the most
often changed part of the mainboard design, the
BIOS information contained in this chapter
(especially the Chipset Setup parameters) may be
a little different compared to the actual BIOS that
came with your mainboard.
3.1Entering the Award BIOS Setup Menu
The BIOS setup utility is a segment of codes/routines residing in the BIOS
Flash ROM. This routine allows you to configure the system parameters and
save the configuration into the 128 byte CMOS area, (normally in the RTC
chip or directly in the main chipset). To enter the BIOS Setup, press
during POST (Power-On Self Test). The BIOS Setup Main Menu appears as
follows.

legacy ISA card. The default is PCI/ISA PnP . Take note
that PCI card does not require DMA channel.

Some old PCI IDE add-on cards are not fully PnP
compatible. These cards require you to specify the
slot in use to enable BIOS to properly configure the
PnP resources. This function allows you to select the
PCI slot for any PCI IDE add-on card present in your
system. Set this item to Auto to allow BIOS to
automatically configure the installed PCI IDE card(s).

These two items, in conjunction with item "PCI IDE
IRQ Map To", specify the IRQ routing of the primary
or secondary channel of the PCI IDE add-on card (not
the onboard IDE). Each PCI slot has four PCI
interrupts aligned as listed in the table below. You
must specify the slot in the "PCI IDE IRQ Map To",
and set the PCI interrupt ( INTx) here according to the
interrupt connection on the card.
This item, in conjunction with the "Used MEM
Length", lets you set a memory space for non-PnP
compatible ISA card. This item specifies the
memory base (start address) of the reserved
memory space. The memory size is specified in the
"Used MEM Length".
PNP/PCI Configuration Used MEM Length
Used MEM Length

If your ISA card is not PnP compatible and requires
special memory space to support its function,
specify the memory size in this parameter to inform
the PnP BIOS to reserve the specified memory
space for installed legacy ISA card.
3.7Load Setup Defaults
The "Load Setup Defaults" option loads optimized settings for optimum
system performance. Optimal settings are relatively safer than the Turbo
settings. We recommend you to use the Optimal settings if your system has
large memory size and fully loaded with add-on card (for example, a file
server using double-sided 8MB SIMM x4 and SCSI plus Network card
occupying the PCI and ISA slots).
3-26
AWARD BIOS
Optimal is not the slowest setting for this mainboard. If you need to verify a
unstable problem, you may manually set the parameter in the "BIOS Features
Setup" and "Chipset Features Setup" to get slowest and safer setting.
3.8Load Turbo Defaults
The "Load Turbo Defaults" option gives better performance than Optimal
values. However, Turbo values may not be the best setting of this mainboard
but these values are qualified by the AOpen RD and QA department as the
reliable settings especially if you have limited loading of add-on card and
memory size (for example, a system that contains only a VGA/Sound card
and two SIMMs).
To attain the best system performance, you may manually set the parameters
in the "Chipset Features Setup" to get proprietary setting. Make sure that you
know and understand the functions of every item in Chipset Setup menu. The
performance difference of Turbo from Optimal is normally around 3% to 10%,
depending on the chipset and the application.

1.At the prompt, type your password. Your password can be up to 8
alphanumeric characters. When you type the characters, they appear as
asterisks on the password screen box.
2.After typing the password, press.
3.At the next prompt, re-type your password and press again to confirm

reverts to the main screen.
To disable the password, press when prompted to enter the password. The

3.11 IDE HDD Auto Detection
If your system has an IDE hard drive, you can use this function to detect its
parameters and enter them into the "Standard CMOS Setup" automatically.
This routine only detects one set of parameters for your IDE hard drive.
Some IDE drives can use more than one set of parameters. If your hard disk
is formatted using different parameters than those detected, you have to enter
the parameters manually. If the parameters listed do not match the ones
used to format the disk, the information on that disk will not be accessible. If
the auto-detected parameters displayed do not match those that used for your
drive, ignore them. Type N to reject the values and enter the correct ones
manually from the Standard CMOS Setup screen.

3.14 NCR SCSI BIOS and Drivers
The NCR 53C810 SCSI BIOS resides in the same flash memory chip as the
system BIOS. The onboard NCR SCSI BIOS is used to support NCR 53C810
SCSI control card without BIOS code.
The NCR SCSI BIOS directly supports DOS, Windows 3.1 and OS/2. For
better system performance, you may use the drivers that come with the NCR
SCSI card or with your operating system. For details, refer to the installation
manual of your NCR 53C810 SCSI card.
3.15 AWARD BIOS Flash Utility
The AWARD Flash utility allows you to upgrade the system BIOS. To get the
AWARD Flash utility and the upgrade BIOS file, contact your local distributor
or visit our homepage at http://www.aopen.com.tw . Please make sure that
you have the correct BIOS ready, the BIOS filename is normally like
AX6FR100.BIN, which means model AX6F BIOS revision 1.00.
There are three useful programs, Onboard IO chip check utility, Checksum
utility CHECKSUM.EXE and AWARD Flash utility AWDFLASH.EXE. Follow
the procedures below to upgrade your BIOS.
[CHECKSUM.EXE]
This utility will help you to determine if the BIOS has been downloaded
correctly or not.
1. Execute
C:> CHECKSUM Biosfile.bin
Biosfile.bin is the filename of the BIOS code.
2. The utility will show "Checksum is ssss".
3. Compare the "ssss" with original checksum posted on Web or BBS. If they
are different, please do not proceed any further and try to download the
BIOS again.
[IO.EXE]
This utility will help you to determine the model of onboard IO chip, as well as
BIOS version. Make sure the BIOS you download supports the onboard IO
chip and the BIOS version is later than the current onboard BIOS.

AWARD BIOS
1. Execute
C:> IO
[AWDFLASH.EXE]
This utility will try to reprogram your system BIOS by using flash memory
technology. It will permanently replace your original BIOS content after
flashing.
1. Bootup the system from DOS prompt without loading any memory
manager (HIMEM, EMM386, QEMM386, ...).
2. Execute
C:> AWDFLASH Biosfile.bin
Biosfile.bin is the filename of the BIOS code.
3. After loading the new BIOS code, the utility will prompt you to save
original BIOS code into your HDD or floppy. Please press "Y" to store it as
"BIOS.OLD".
4. After the old BIOS has been successfully saved, press "Y" to replace
BIOS.
5. DO NOT turn off the power during "FLASHING".
6. Reboot the system by turn off the power after "FLASHING".
7. Press "DEL" key to enter BIOS setup during POST.
8. Reload the "BIOS SETUP DEFAULT" and reconfigure other items as
previous set.
9. Save & Exit. Done!
3-36
Warning: DO NOT turn off the power during
"FLASHING". If the BIOS programming is not
successfully finished, the system will not be boot
again, and you may need to physically replace the
BIOS chip.
Tip: You may load back original BIOS "BIOS.OLD"
by the same procedure.
