64mb should be more then enough for maxx software, and that wary linux cd. Im pretty sure it can run on even as low as 4mb. Im thinking you should try the process of elimination. Try one stick at a time, try swapping as many as you have. One at a time. If none of them get past this issue, then I honestly dont know besides CMOS settings, or an issue with the cd drive your using. For what its worth, i have had a cdrom drive not load a force install disc. It goes back yo what i was saying about old hardware not playing nice with newer hardware.
