I know a lot of people have been having trouble booting from the Matsushita
(a.k.a. "Matshita") CR-506-B 8x CD-ROM drive used in many SuperMacs.

This just came back to me:  There's a "Sector Size" jumper on the back of
the CD-ROM drive.  The drive often can't boot a bootable CD when this jumper
is in place.  In many cases, simply pulling this jumper solved the problem.
The only downside, if I recall correctly, is that CD-ROM Toolkit may falsely
report that the disc is damaged IF you have the "Allow messages about badly
mastered CD's" option selected in the CDT setup menu.  The disc is most
likely not damaged, and should boot just fine.

There may be other elements of this that I'm not remembering, but try
starting with that jumper.

This also holds true for the 24x Matsushita drives.  These were less common,
and I can't recall the model number now (possibly CR-585).

Hope this helps.
