¥ 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

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 mainboardÕs 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.

MS5120 Mainboard Manual
16
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.
