The ASW-410 CDROM driver only supports audio on the Sony and Toshiba CDROM
drives.  If the NEC emulates the command set of either of these drives, it
will work fine, as far as audio goes.
In general, there is a command line switch that allows the driver to function
with virtually any CDROM driver, except the audio command, which was not
defined for SCSI-1 and so the manaufacturers implemented it in many different
ways.
A new version of the driver which supports the SCSI-2 CDROM command set is
on its way out the door.  So any CDROM that is SCSI-2 compatible, and not
just claims to be SCSI-2 compatible, will function in all aspects.
Take care though,.....some CDROMS (like Toshiba) will barf and puke if the
synchronous negotiation message is sent to the device, so you must make sure
sync negotiation is off on the adapter (default), if you have any problems.
