Exactly which version of knoppix are you using?
What you just said does not fit my understanding and experience with knoppix.
I'm using knoppix 5.1.1 DVD-2007-01-04-EN
I'm pretty sure that behaves just like the CD version of 5.1.1 (but has more optional packages installed).
It does NOT need to decompress to HD. It runs just fine for me on systems with no HD and on systems where it doesn't understand the raid HD.
From what you said so far, your problem sounds like an IDE cable problem, or maybe incorrect settings in whatever IDE configuration your BIOS supports, or maybe the IDE port is just broken on that motherboard.
