Chapter 3
Award BIOS
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.
3.1 Entering 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.

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.
3.7 Load 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.
3.8 Load 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.

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.
