Sorry for the late summary. My original question was how to get non-Sun CDROM
drives to work with Suns. Thanks for all your suggestions. Unfortunately ether
they
didn't work or I wasunable to implement them.

The responses came under the following categories:

"Cut traces on the CD-ROM circuit board"
--Sorry, I'm only borrowing the CD-ROM. The owners wouldn't be too happy about
that.
--However, I could buy one of my own and do it. I was trying to avoid that,
though. (buying
--my own drive, that is. Cutting traces doesn't bother me )

"use adb to modify kernel"
--All the examples I saw were for Solaris 2.1(SunOS 5.1) or SunOS 4.x.x . I'm
running Solaris
2.3(SunOS 5.3),

"C programs to set the block size on the CD-ROM drive via SCSI commands"
--See above.

"Shut down volume management and mount the CD-ROM manually
--No go!!

"stop volume management, insert CD into drive, and restart volume management"
--Nope.

Of course nearly everyone pointed out the fact that Sun's CD-ROM driver only
supports a block size
of 512 bytes: a fact I didn't know. I also got some great info out of the CD-ROM
faq which some of
you were kind enough to send me.

Oh, the drive was a Toshiba XM3401.
