Due to my supposedly weird hardware, I've got bad news - Knoppix 4.0.2 does not even boot on my system (and I was sooo much looking forward to Kernal 2.6.12 )

Ok, first facts first. My hardware:
AMD 1200 MHZ Athlon Socket A ; 660 MB Ram
Gigabyte 7IXE4 Motherboard ; AGP, PCI, ISA, USB 1.1, Par+Ser onboard
Net: 3com 3c900 Combo PCI
Highpoint 370/2 IDE Controller PCI
NEC USB 2.0 Controller PCI
SB-16 PnP ISA

The booting? I insert the CD, press return. The screen goes blank and nothing happens. Not even the usual Linux pinguin appears at the top left corner. Just absolutely nothing. It freezes after saying "loading minirt.gz" or something.

The same CD boots more or less fine on a dual 350 MHZ computer just nearby, so it must be something else.
