16-bit Applications Hang Using Sony CDU 3x CD-ROM

• Microsoft Windows NT Server version 3.5

SYMPTOMS

After you upgrade to Windows NT version 3.5 Service Pack 2, the following problems occur with the Sony CDU 3X CD-ROM drive:

   - During Windows NT startup, the CD-ROM drive takes a long period
     of time to initialize.

   - When you run a 16-bit application, the CD-ROM drive light is active
     and the application stops responding (hangs).

WORKAROUND

To work around this problem, do one of the following:

• Place a CD-ROM disc in the drive before you start Windows NT.

  -or-

• Replace the SLCD32.SYS file in your %SystemRoot%\SYSTEM32\DRIVERS subdirectory with the older file of the same name located in the I386 directory of the Windows NT Server or Workstation 3.5 CD-ROM disc.
