Thanks, but cheatcodes or anything else ain't squat when the monitor is tearing, right?
I never said I had the mindset of writing it off, so the True Believers can stand down. Maybe my ISO was corrupted, since it was almost 700 mb's, and maybe someday I'll try again.
I'm assuming at the moment that you get at least to the boot screen where you have to hit enter to continue. If that's not the case, then I'd suspect the CD, because just about any modern computer should make it that far.
First, I'd try
knoppix screen=1280x1024
..at that boot prompt. Type the above, hit enter, and see what happens...
Next, I'd try
knoppix noscsi
I don't know why this sometimes works on systems that have issues, but it does.
Just in case...
knoppix nodma
One more...
knoppix fb1024x768
I'd be interested in knowing if any of these make it work for you.
