If you have a Rev. C apple SCSI or the "high speed" DMA SCSI, all you have to
do is add it to the chain (you may have to shuffle some terminators depending
on how many devices you have and where your termination currently is).

ProDOS 8 will recognize ProDOS partitions on the CD immediately.

GS/OS will recognize the CD ROM's after you install a driver (make sure you
use the installer that came with the DMA SCSI card if that's what you have).
GS/OS will also recognize High Sierra (I think ISO 9660 too but I'm not sure)
partitions &/or CDs once you have installed CD ROM on your boot disk and
rebooted. (Installer will probably force you to reboot because it knows this.)

If you have a RamFast, you'll need to wait for a ROM upgrade from CVT which is
supposed to be in the works.

I don't know about the other SCSI cards that are out there.
