This article was previously published under Q121926 SYMPTOMS
When you install Windows 95 on a system with two CD-ROM drives, one of the
CD-ROM drives is not detected.
CAUSE
This problem occurs when Windows 95 loads protected-mode drivers for one of
the CD-ROM drives and the second CD-ROM drive is running with real-mode
drivers loading in the CONFIG.SYS and AUTOEXEC.BAT files. Windows 95
assumes that the real-mode and protected-mode drivers reference the exact
same drive; therefore, it assigns the drive letter for the protected-mode
drive to be the same as the existing real-mode drive letter.
RESOLUTION
Assign the CD-ROM drive running in protected mode to a different drive
letter.
You can change the drive letter of a CD-ROM drive by performing the
following steps:
- Click the Start button, point to Settings, and then click Control Panel.
- Double-click the System icon, then click the Device Manager tab.
- Select the CD-ROM you want to change from the list, then click the
Properties button.
- Click the Settings tab.
- In the Reserved Drive Letters section, set Start Drive Letter and
End Drive Letter to the drive letter you want the CD-ROM to use.
Click the OK button.
- Click the Start button on the taskbar and click Shut Down. Then
click Restart The Computer.
The CD-ROM drive letter should now be the letter you selected and the
second CD-ROM should be accessible.
To change the drive letter of the CD-ROM using MSCDEX, use the MSCDEX /L:
switch on the MSCDEX line in the AUTOEXEC.BAT file. For example, inserting
a /L:E on the MSCDEX line would change the drive letter of the of the
CD-ROM using MSCDEX to E.
