I'm using the new 3.2 knoppix version and it works fine but I've a little troubleshooting which appear with this new version.
I've tested 3.2 version on 3 PC :
1 - main board abit 3 yars old with celeron 466 Mhz-> no problem.
2 - main board abit VH6 with celeron 800 Mhz-> no problem
3 - main board gigabyte 7vrxp witn athlon 1800+-> no boot screen only a blue screen and an error on the startup "only one processor found" but knoppix is running correctly.

It's not very important but if somebody have an idea I'm interesting?
