How to flash motherboard BIOS from Linux (no DOS/Windows, no floppy drive)?

Step 1: Download FreeDOS boot disk floppy image




wget http://www.fdos.org/bootdisks/autogen/FDOEM.144.gz


gunzip FDOEM.144.gz



Step 2: Copy your BIOS flash utility and new BIOS image to the mounted floppy disk image




mkdir /tmp/floppy


mount -t vfat -o loop FDOEM.144 /tmp/floppy




# cp 75DVSTA2.60 ASRflash.exe /tmp/floppy



Step 3: Burn a bootable CD which will emulate floppy device for us




mkisofs -o bootcd.iso -b FDOEM.144 FDOEM.144


cdrecord -v bootcd.iso



Step 4: Reboot, flash, reboot, enjoy your new BIOS
