I recently got a knoppix 4.0.2 disk at school and played around with it a little bit there (it works). However, when I go to my home PCs, I get numerous error messages and in the end the screen goes black and it never boots.

1) With the CD in I turn the PC on and the splash screen (with boot comes up, I hit enter.
2) I get these error messages. I tried taking a picture of them with my dig. camera, though it didn't turn out too great.

Something about buffer read i/o error on device hdc. Being completely new to Linux I can't say I understand any of it. I was hoping you guys could help me out here and get this thing to work on my computers.

3) The process gets to autoconfiguring devices and hangs with a full bar for a few minutes.
4) The screen goes black and nothing else ever happens.

This is almost the same on both of my computers, and I thought it might be the CD but it worked at school and it looks like it's in good shape (no scratches, etc). Any help you can offer would be great.

Specs on the computer I'm trying it on: Hewlett Packard (groan, I know, tell me about it), AMD 2800, Radeon X800XL video card, 2x 512 Corsair value RAM. If you need anything else let me know.
