I think your BIOS is actually ok, sorry my e-mail was a bit of a stream of 
conciousness.

Ah, if you have a working machine where you can build a kernel, you can build 
an new CD using an existing ISO as a template.  Simply build a GENERIC kernel 
and install it into some DESTDIR=/foo and mount the ISO image using mdconfig 
to /dist.  Then do something like 'mkisofs -o new.iso -r -J -b 
boot/cdboot -no-emul-boot -x /dist/boot/kernel /dist /foo'.  If that 
complains about duplicate 'boot/kernel' then you may need to copy all 
of /dist/boot to /foo/boot, install the new kernel into /foo, and 
use '-x /dist/boot /dist /foo'.

Also, if this machine supports PXE boot at all, that can be a way to boot a 
test kernel as well.
