How to: Force Windows 95 to use real mode CD-ROM drivers.
Solution:
Provide real-mode driver ability by removing the appropriate 'rem - By Windows Setup -' phrase in AUTOEXEC.BAT and CONFIG.SYS (CONFIG.SYS may not be affected.) This will force Windows 95 to use real-mode drivers.
NOTE 1: The driver name is unique to each particular CD-ROM drive.
NOTE 2: Verify that the latest copy of MSCDEX.EXE and CD-ROM driver is available to the system in the directory specified in AUTOEXEC.BAT and CONFIG.SYS.
