Searched through the postings, but haven't found this one yet:

When I attempt to update the 1003 BIOS on my A7V8X-X using EZ Update,
I get an error message right after the update program reads the new
BIOS file from the floppy. Something about not "matching the
onboard", then "press any key to reboot" which aborts the update
leaving old 1003 BIOS untouched. I've tried 1004, 1005, and even 1006
beta with the same result. Also tried removing Supervisor password
from BIOS first - no change. What gives?
