Adding Non-SCSI CD-ROM Drivers After Installing Windows NT

SUMMARY

If you install Windows NT without adding a driver for your non-SCSI CD-ROM drive and you do not have a complete set of the Windows NT setup floppy disks, you can add support for the drive after installation by copying the proper driver from one of the three Windows NT Setup Boot Disks or from the Windows NT 3.5x CD-ROM disc on another computer.

MORE INFORMATION

Windows NT Setup does not autodetect the existence of non-SCSI CD-ROM drives. Therefore, if you perform setup using either WINNT.EXE or WINNT32.EXE and you do not specifically tell Setup to add the driver for the non-SCSI CD-ROM drive, Windows NT will install without adding driver.

If you then attempt to add the driver for your non-SCSI CD-ROM drive using the Windows NT Setup icon, you will be prompted to insert either the Windows NT CD-ROM or one of the Windows NT Setup disks. Because some packages of Windows NT include only the CD-ROM Setup Disc and three Setup Boot Disks (not the complete floppy setup disk set), you might not be able to insert the requested disk. This typically happens with the following drives:

   Panasonic
   Sony
   Mitsumi
   IDE Interface drive
   Creative Labs Sound Blaster CD-ROM Interface

To work around this problem:

Copy the proper non-SCSI CD-ROM or sound card driver (see the table below for the driver name and location) from one of the three Windows NT Setup Boot Disks to the following directory:
\%SystemRoot%\SYSTEM32\DRIVERS
If you do not have the three boot floppies and cannot access the CD-ROM drive, copy the required driver file to a floppy disk from another computer that can access the Windows NT CD-ROM disc, and then copy the driver file from the floppy disk to the root directory of drive C on the computer that requires the driver. You may also copy the driver file over a network.
From the Program Manager Main group, run Windows NT Setup.
From the Options menu, choose Add/Remove SCSI Adapters.
Choose Add.
Select the driver for your non-SCSI CD-ROM drive and choose Install.

NOTE: The Sound Blaster CD-ROM driver is not listed by name in Windows NT Setup under Options after you select Add SCSI driver.
When asked for the location of the driver, specify \%SystemRoot%\SYSTEM32\DRIVERS or C:\, depending on what you did in step 1.
If you are notified that the driver already exists on the system, choose the Current button.
Choose Close and quit Windows NT Setup.
Shutdown and restart Windows NT.
