Is the max transfer a value determined by the CDROM drive itself?
MaxTransfer is for the hard drive. Shouldn't have to change anything for the CD.
Check your 3.9 CD for scratches or errors? You can't boot from the CD itself, need to boot from the recovery disk, but the old saying "garbage in, garbage out" - if it's copying damaged files from the CD it'll stop you right there.
And SetPatch does a lot of things, including enabling enhanced graphics modes, turning on processor caches, and loading various device drivers. I did a quick google search to see if I could find a full doc for it but nothing was coming up, but suffice to say, you need it.

...more later, busy at work today.
