I suggest you use the simple harmless way (i.e. bad BIOS equals dead computer). Use a ...dun dun dun!!! BOOT FLOPPY. Insert a floppy into ur floppy drive, right-Click the drive and hit format (do the full thing, no quickie crap). Then go into the Knoppix cd and go into firectory Knoppix and double-click mkfloppy.bat. This will make the boot floppy. Insert the floppy and cd. Shutdown comp and restart and enjoy Knoppix beauty (i'm in Knoppix now as I type )
