Problems booting. freezes when booting

[jtsymbo]

Brand new to Linux. Was able to test drive Knoppix 4.02 on another computer at work. Liked what I saw. Trying to boot on my home computer but freezes getting the message "No Suitable X-server found on your card". I have an ATI Radeon Xpress 200 video chipset on my motherboard. Am able to boot SLAX linux on the home computer w/o problems. Please help out a newbie who wants to explore the wonderful world of Knoppix. Is there a cheat code I can enter?
Thanks!!!

Oh, yes I almost forgot. I did verify my ISO Image with md5sum.

Figured it out on my own... I have a Sony 19" LCD. I had to change the refresh rate on it to 60hz.
Boot: knoppix xvrefresh=60.
work.
