I get this error when I boot my machine I have tried to load AWDFLASH from a disk and it won't work. Thank you.
Bios Rom CheckSum Error
Automatic Load AWDFLASH.EXE !!ERROR -- LOAD AWDFLASH.EXE Failed! Replace the disk and press enter.

We'd need a bit more information to be sure, but it sounds as though you're trying to upgrade your PC's Bios with a flash upgrade that's either the wrong one, or that doesn't recognise the current Bios.
Be careful, as it's quite easy to wipe the Bios completely and then have to either replace the chip (difficult/impossible on newer boards) or throw the motherboard away.
