I've never tried Linux before, but I would really like to do so. However, I'm having problems getting this OS started.
---
Computer 1
When I get past the boot prompt, I get this message:


You have passed an undefined mode number. Press <RETURN> to see video modes available, <SPACE> to continue or wait 30 secs

I try all the options for the video numbers (0 through 6, i think it is), and I try the scan. I also tried skipping the video mode list.... but no matter what, the OS won't start. It gives me a blank screen.

I've checked the md5 checksums, and everything's fine there. Also, I did burned the disc as an ISO image file. I didn't extract.

Computer 2
Here's what happens... I get the message about the undefined mode number. When I get past that, this is what happens..............


Can't find KNOPPIX filesystem, sorry. Dropping you to a (very limited) shell. Press reset button to quit.

Additional builtin commands available

cat mount unmount
insmod rmmod lsmod

Knoppix#
I get a prompt right after "Knoppix#".

Computer 3
Cloop errors. Knoppix does not start.

I verified the md5s, which were identical. Also, I burned it three different times, but neither cd seems to work. I even made the third burn on computer 2, but I'm still having the same exact problems. =/

Anyone have some help to offer? thanks in advance!
