There are two types of CD-ROMs: SCSI and IDE. 
In order to determine the driver you need, first determine the make and model 
number of your NEC Technologies CD-ROM (CDR-xxxx - located on top of the CD-ROM reader or 
if external located on the back or bottom of the unit) or NEC Technologies SCSI interface 
(printed on the SCSI card), then look at the table below.
 
NEC Technologies SCSI CD-ROM device drivers are specific to the SCSI interface, 
not the CD-ROM reader itself. If you have an IDE CD-ROM, the drivers are specific 
to the CD-ROM model number. If you have a NEC Technologies SCSI interface, 
you can download the driver files off the NEC Technologies WEB site (http://www.nectech.com/css),
FTP sites (ftp://ftp.nectech.com) or the BBS (630-467-4363). 
The model numbers of the NEC Technologies SCSI interfaces, IDE CD-ROMS are listed below: 
 

For the Trantor T-160 (CD-AT160) and Future Domain TMC-1610MNEC (CD-AT160FD),
SCSI interface for Windows 95/98 are built into the operating system.
