Yes, I learned that from the guide I linked to. Alas, things are
different enough that I haven't been able to get the drive to boot yet.
You posted "F12 gets me to BIOS. If I do, it goes right to the grub
prompt".
So that no longer works? Unless you made changes to the BIOS settings,
this indicates a hardware problem. How good is the battery? A very old
battery may
cause problems even when running with the power adapter connected.
The first step in diagnosis would be careful measurement of voltages at key
points (maybe after checking for bulging electrolytic capacitors).
The only reason for attempting a diagnosis would be to confirm the
system is beyond economical repair.
