[hp omnibook 510] Stops booting

Hello,

I have a HP omnibook 510 and a Knoppix cd 3.7. The cd boots fine in other machines but when i put it in mij laptop it doesn't work.
I get the knoppix prompt and when I enter he goes until the init.
There he hangs and my CPU isn't detected.
My notobook is mentioned at linux laptops and I already tried to change the framebuffer or start failsafe.

Now I'm stuck. Any help?

i have the same notebook and the same problem
how did you solve it?
bye
