Apple //gs RamFAST/SCSI with CD-ROM troubles

I have a sweet Apple //gs set-up that has a RamFAST/SCSI controller
inside. It works great with SCSI hard drives, no so great with CD-ROM

The CD-ROM drive I'm using is an AppleCD 300 which according to the Apple
//gs CD-ROM FAQ is one of the more compatible CD-ROM drives for the //gs.

Apple //gs CD-ROM FAQ:

At any rate, a lot of different drives are supposed to work with the
RamFAST/SCSI card. I believe my biggest problem is that the ROMs on the
board are Version 1, whereas the FAQ says the "best" is Version 3.01, on a
Revision D board (mine's Revision C). The 3.01 ROMs can run "any" CD-ROM
drive "without any extra drivers required".

I can get the CD-ROM drive to coexist with an external HD just fine. The
first problem is I don't have an Apple //gs specific CD, so I'm trying out
various older Mac CDs. If I boot into the RamFAST ROM utilities, I can
see the CD-ROM drive. I can get information about it. I can even get it
to see the partition(s) on the CD-ROM. I can save the configuration and
boot into GS/OS. But when GS/OS starts finding all the drives, it
complains that the CD-ROM is foreign and wants to initialize it. I have
the HS.FST driver installed, which should give GS/OS the ability to mount
ISO 9660/High Sierra and Mac HFS CD-ROMs, but it won't. I've tried discs
in the 1992-1994 timeframe with no success.

One possible "clue" is that when I first mount the CD-ROM drive and the
RamFAST card doesn't have it in its configuration yet, it complains that
the CD-ROM is uninitialized. According to the manual, this could mean
that the CD or the drive is not reporting that it uses 512 byte blocks.
Something like that. But I can "format" the CD-ROM, which really just
allows the SCSI card to see the CD-ROM (finds its partitions, label, etc.)
and sorta mounts it. But GS/OS doesn't like it.

Has anyone played around with CD-ROM drives on the Apple //gs at any
