With KNOPPIX running: ALT-F2 (pops up a command prompt),
and then type in:

upgrader empeg_ip_addr car2-developer-v2.00.upgrade

Of course, one first has to grab the upgrader and .upgrade files, and copy them into KNOPPIX. This would involve some point and click with the mouse, and so may be too complex for most of us..
