Q: After flashing the bios and rebooting the system, the screen went blank.
A: For AMI BIOS
Rename the desired AMI BIOS file to AMIBOOT.ROM and save it on a
floppy disk. e.g. Rename A569MS23.ROM to AMIBOOT.ROM
Insert this floppy disk in the floppy drive. Turn On the system and press
and hold Ctrl-Home to force update. It will read the AMIBOOT.ROM file
and recover the BIOS from the A drive.
When 4 beeps are heard you may remove the floppy disk and restart the
computer.
For Award BIOS
Make a bootable floopy disk
Copy the Award flash utility & BIOS file to the said floppy disk
Create an autoexec.bat with "awdfl535 biosfilename" in the content e.g.
awdfl535 a619mj21.bin
Boot up system with the said floppy (it will take less than 2 minutes before
screen comes out)
Re-flash the BIOS & reboot.
