if you have DOS installed on that machine,
load the cdrom-drivers,
copy the KNOPPIX directory (including files) to harddisk.
then, read the cheatcodes.

when booting the Knoppix diskette you'll need something like:
KNOPPIX FROMHD

exact syntax is mentioned on the cheatcodes textfile.
or maybe F2 or F3 when booting the diskette into Syslinux.

good luck
