Both BIOSes are both stored in a 128k binary file that is written directly into the ROM. However, the AMI BIOS uses a flash routine IN the ROM, so you can not flash AMI BIOS with the AMI update utility since there isn't any support in the Award BIOS. The Award utility checks the checksum-equivelent to make sure the Award BIOS is intact, but of course, it isn't, since it is AMI BIOS. I hope this makes more sense. You can flash the BIOS if you can trick the utility (or write your own). Kevin
