Howard:
You might want to repost this question in the OS2USER forum… but in general
OS/2 is very friendly to any CDROM drive that attaches via a SCSI host adapter.
There is a set of drivers for a variety of different CDROM drives in one of the
OS/2 forums (sorry, I don't use CDROM yet and don't know exactly where, but
I've seen it discussed in the forum).
If your drive isn't SCSI and if Sony doesn't provide a driver, you can still
load your DOS drivers in a DOS session and access the CDROM from there – but
OS/2 in general won't be able to access it.
