Sounds like a compatibility issue with the video card.  Try a Deja News
search in comp.os.linux.hardware to see if anyone there has solved the
problem.

/mbr is an option for DOS fdisk, not Linux.  But you don't want to do
that anyway 'cause it will wipe out LILO.  Instead, add this to your
lilo.conf:

  other=/dev/hda1
     label=dos
     table=/dev/hda

then rerun lilo, reboot and type "dos" at the prompt.

Hope this helps...
