You can use old non-sun cd drives all you want....here is a tech note on
what it wants. Most cd drives have jumpers to reset the block size of the
drive...especially older scsi-I drives.

SunOS 5 (or 4, for that matter) _will_ ask the cdrom what its block size
is. OpenPROM won't. The difference is that you can use any CD-ROM with
SunOS, but you can only boot off of ones capable of a 512 byte block
size.
Which is not saying that Sun shouldn't make a more flexible boot ROM,
but that won't help existing older Suns, which are exactly the systems
we support...
