Yes, dual CPU. Two mighty 200MHz Pentium Pro... But no, I don't think the kernel on the CD works. This failure occurs as soon as I press enter at the initial prompt after booting the CD. I've tried "linux memmap=exactmap mem=640k@0 mem=95m@1m rpmarch=1586" at that prompt, but it doesn't help. What is the message actually telling me?
