Excuse me, but this doesn't make sense.
my cmos battery was reset naturally resetting the mbr
cmos battery has nothing to do with mbr.
If you lost lilo or mbr was overwritten somehow, you have some other problem. If this is an older computer maybe only the harddrive-definition in BIOS setup is lost.
Try accessing setup, choose harddisk auto-detection (or just add your disk manually if you can).
Then you should get your lilo-menu.
The X-server in Knoppix... well, I believe you can't do anything about that as Knoppix is a live-CD. Correct me someone if I'm wrong?
