KnoppixMAME will not boot

Sorry if this is the wrong forum, but I am having trouble getting KnoppixMAME to boot on one of my computers. It boots fine on an older computer I have, but not on the one I had planned to use it on. The error I get is one that a lot of people seem to get, the "Can't find KNOPPIX Filesystem" error. Originally I thought it might be looking in the wrong place, because I have a CD-RW drive and a CD-ROM drive, and I was trying to boot from the Secondary Slave drive. I switched the drives around but it still does not work. I know it must be something with the hardware configuration of this computer since it works on the older PC. Is there a boot: option I could try that might fix this?
