Flash Writer Utility
The AMI Flash Writer Utility is now included in the AMIBIOS (S1857-B &
S1857A-B) and so it is simpler to upgrade the BIOS of your mainboard. The
system BIOS is stored on a flash EEPROM ROM chip on the mainboard which
can be erased and reprogrammed by following the directions below.
1. From the DOS prompt, rename the BIOS file that you have downloaded to
amiboot.rom and copy it on to a floppy disk.
2. Insert the floppy disk with the BIOS upgrade into the A: drive.
3. Turn the power off.
4. While holding the <Ctrl> and <Home> keys, turn the power on. The system
will begin to read from the A: drive, and write the BIOS information contained
on the floppy disk in that drive to the EEPROM ROM chip. When the BIOS
has been totally reprogrammed, the system will reboot with the new BIOS in
operation.
5. If the system does not reboot in three minutes, power down the system wait
a few seconds, and then turn the power back on again. You will be prompted to
press <F1> to run Setup. You may check your settings at this time, or simply
save and exit the program.
The AWARDBIOS Flash writer utility is now included in the AWARDBIOS.
Like the AmiBIOS, the AWARDBIOS can be upgraded by reprogramming the
flash EEPROM ROM chip on the mainboard. Follow the instructions below for
a quick and easy upgrade to your BIOS. (For more detailed instructions please
refer to the AWARDBIOS settings chapter. S1857 & S1857A only)
1. Download the AWDFLASH.exe from the Tyan website
2. Download the latest AWARDBIOS update for your motherboard.
3. Copy both the AWDFLASH.EXE & *.BIN files to a floppy disk.
4. Reboot system to DOS mode.
5. Insert floppy disk with the BIOS upgrade into the A: drive
6. Type AWDFLASH.EXE x.BIN x being the filename of the BIOS upgrade.
7. The program will ask you to backup your existing BIOS file, select yes.
8. You are then prompted to reboot, select yes
9. The program will ask you are you sure?, select yes.
10. If the system does not reboot in three minutes, power down the system
wait a few seconds, and then turn the power back on again. You will be
prompted to press <Delete> to run Setup. You may check your settings at
this time, or simply save and exit the program.
