If Mandrake used LILO to install, there very well might be a backup in
/boot/boot.0800 or something like that.  You might want to consult the
LILO documentation and/or a net search to see if they say how to restore
this (probably using dd).

If you have real W2K media, it has boot floppies and a CD.  You can boot
from floppy to access the CD, and then run recovery mode.  It might be
able to fix this up.  Then again, it might demand that you had made an
emergency recovery disk from within W2K, something I learned the hard
way once.

Yes. Just get back up using the floppy boot disk that you must
have made. Then look in /boot. You should see boot.0800. This
is 512k in size. It is the original boot sector. Now, make damn
sure that you know the raw device used to boot the machine!

It is probably /dev/hda if you have IDE drives or /dev/sda if
you have SCSI, just do `od /dev/whatever` and if the Disk drive
LED comes on, you have found it.

Then, simply:
	cp /boot/boot.0800 /dev/whatever

Since boot.0800 is already the correct length, you don't have to
use anything else.

Ah, but that reverts the partition table, which may have been changed
since first installing lilo.  To avoid this, just type 'lilo -U', which
does much the same thing but without touching the partition table.
