I have a laptop (HP Pavilion) running XP Home. I recently installed SP2 and all the rest of the patches, and I am now unable to either view the contents of any knoppix cds in windows, or boot from them. I downloaded and burned the latest CD image (5.1.1), and it also is failing to be recognized on this laptop. Under windows, either an error message "not available: incorrect function" is given, or the CPU useage skyrockets to the point where nothing responds, and I have to force a power-off. Booting from any of the knoppix cds that I have fail with the cd not being recognized as bootable. Before I installed the SP2 and patches, I was able to boot into the knoppix 5.0.1 cd that I have, as well as the ealier versions.

I realize that SP2 should not have any effect on whether the BIOS recognizes the cd as bootable, but since that is the only thing that changed, I am at a loss. Any one have any ideas?

Edit - It should also be noted, that I can mount the cds under a linux box that I have, so there is nothing wrong with the burn.
