I'm attempting to boot Knoppix v3.8.2 on a system with a GeForce FX 5500 video card, and updated drivers. My standard OS is Windows XP, service pack 2. I'm attempting to load from a CD. After the command prompt the devices load properly, but when the screen reloads, it generally goes blank, but every three or four seconds, I get what appear to be two parallel red lines that flicker for only a frame at a time. The lines are about 10% the width of the screen, and are centered. They may be some sort of error display, but I can't make them out for the life of me.

I wrote the disk at 10x, used the checksum, and I've tried several "cheatcodes" based on advice in other threads:

knoppix screen=1024x768 vsync 60

and I've tried a couple vga options, but none seem to affect my problem.


I hope I presented my situation well, thanks in advance for your help.
