Change your CD-ROM drive designation
The following situation is very familiar to everyone who ever added a new hard drive, or repartitioned his existing hard drives; the CD-ROM drive letter changes automatically to the next letter after the last logical drive. In other words, if your CD-ROM used to be designated as D:, it will get bumped up a letter and now be recognized by the system as E:. This causes many applications that use a static configuration to lose contact with the CD-ROM drive, and stop working properly.
It's possible to counter this problem by assigning a constant letter (drive designation) to the CD-ROM drive, either under DOS and/or Windows 95.
To assign a constant drive designation in real-mode (MS-DOS and Windows 95 in MS-DOS mode) add the letter assignment parameter to MSCDEX.EXE. For example: MSCDEX /D:MSCD000 /L:I assigns the letter I: to the first CD-ROM drive in your system. Note that under DOS mode, the first CD-ROM letter must come after the last hard drive letter.
To assign a constant drive designation in Windows 95, start Control Panel and open the System Properties window and select the Device Manager tab. Click on the [+] next to the CD-ROM entry and a list of all your available CD-ROM drives will appear under it. Select the appropriate CD-ROM drive from the list, click the Properties button and go to the Settings page. Near the bottom there's a section where you can see the Current Drive Assignment as well as all of the Reserved Drive Letters. Enter your new choice for the Start and End drive letter.
Note: If you change this designation to Z:, it will be a LONG time before you have to worry about changing it again.
