Yeah, I just had the same problem this weekend.  I have a DAK BSR cdrom (

I've a MATSUSHITA SCSI CD-ROM 54XX , AHA1542B.
Try to patch the cdrom.sys for your manufacture  Id e.g. SONY,
Include in your config.sys
basedev=os2scsi.dmd
device=patched_cdrom.sys
after 
basedev=aha154x.add

Perhaps it'll work.

My CD-ROM is visible and accessible in a  DOS-BOX and OS/2.

But anyway the actual mscdex does not work in a dos box. 
( Incorrect dos version, you'll know why)
But i think the mscdex is required for audio capability only, because the 
drive appears as a CD-ROM drive in the system.

Don't forget , patching voids your warranty.
