Then there is hope.
Have a look at the manual section 2.1.3 "Recovering the BIOS with
Crashfree BIOS 2". When you turn on the machine, do you see the
"Bad BIOS checksum" message ? If so, then all you need is a
floppy with the file A7V600.rom on it. This file is a copy of
the BIOS, renamed to that particular file name, as that is
what Crashfree is programmed to look for.
It is also possible your motherboard CD has a copy of A7V600.rom
at the root level, and shoving the CD in the CD drive will work
in the same way.
You can also try using <alt> <F2> at POST, and flash using the
built-in EZflash. This is basically the same flashing capability.
If none of this is working, try clearing the CMOS, remembering
to unplug the macnine before doing the procedure. Unplugging the
computer helps ensure that there is no +5VSB present when the CMOS
jumper is shorted.
If you succeed in flashing, enter the BIOS and do "Load Setup
Defaults", as a way to align the data structures in the CMOS
with what the BIOS expects.
