How to Identify Your BIOS
Boot-up your computer. Look at the top left corner for RELEASE DATE FOR THE BIOS. You will find L or S at the end of the release date. (Example: 04/28/1997L or 04/28/1997S)
How to Update and Flash Your BIOS
Download the correct BIOS files from our website or BBS Uncompress files into a temporary directory ( you should end up with two files) Boot the system without using any memory manages either from bootable floppy disk or internal hard disk Run the flash utility (awflash.exe) and enter the full name of XXXX.bin file Follow the screen instructions to update the BIOS (Do not turn off the power during flash) After a successful flash, power down the system and clear the CMOS with the appropriate jumper (Please refer to motherboard manual to find the proper jumper). Short the jumper for 5-10 seconds then remove the jumper and power the system on. This will clear any extraneous data that may have been kept from the previous version of the BIOS.

Award BIOS Setup

The mainboard comes with the Award BIOS chip that contains the ROM Setup information of your system. This chip serves as an interface between the processor and the rest of the mainboards components. This chapter explains the information contained in the Setup program and tells you how to modify the settings according to your system configuration.

CMOS Setup Utility

A Setup program, built into the system BIOS, is stored in the CMOS RAM that allows the configuration settings to be changed. This program is executed when the user changes system configuration, the user changes system backup battery, or the system detects a configuration error and asks the user to run the Setup program.

Standard CMOS Setup

System BIOS automatically detects memory size, thus no changes are necessary. However several items may require setting such as the system Date and Time, IDE hard disk, floppy disk drive types for drive A: and B:, boot up video display mode, or POST error handkling selection. Use the arrow keys to highlight the item and then use the PgUp, or PgDn keys to select the value you want in each item.

Hard Disk Configurations

TYPE Select from 1 to 45 to fill remaining fields with predefined values of disk drives. Select User to fill the remaining fields. Select Auto to detect the HDD type automatically. 15
MS5120 Mainboard Manual SIZE The hard disk size in Mega bytes. CYLS The cylinder number of the hard disk. HEAD The read/write head number of hard disk. The range is from 1 to 16. PRECOMP The cylinder number at which the disk drive changes the write timing. LANDZ The cylinder number that the disk drive heads (read/write) are seated when the disk drive is parked. SECTOR The sector number of each track defined on the hard disk. The range is from 1 to 64. MODE Select Auto to detect the mode type automatically. If your hard disk supports the LBA mode, select LBA or Large. However, if your hard disk cylinder is more than 1024 and does not support the LBA function, then use the large setting. Select Normal if your hard disk supports 1024 cylinders or below 1024.

BIOS Features Setup

Moving around the BIOS and Chipset Features Setup programs (refer to the next section) works the same way as moving around the Standard CMOS Setup program. Users are not encouraged to run the BIOS and Chipset Features Setup programs. Your system should have been fine-tuned before shipping. Improper Setup may cause the system to fail, so consult your dealer before making any changes.
