    I am working with an older computer with Windows95 on it and I was trying to install a Dos based golf game from a CD. You have to restart the computer in MS-DOS mode to install. There are two hard drives in the computer (drives c: and d:) and the CD-Rom is drive e:. At the Dos prompt when I type e:install I get a message that this is an invalid drive specification. But in Windows 95 when I look in My Computer or Windows Explorer drive e: shows up with the CD named and I can view the files on the CD.
    Why won't Dos let me use drive e:?

    You need the DOS CD drivers running to access CD's from DOS. It's been a long time since I tinkered with W95. One method might be to boot from a DOS floppy with CD support and install that way.

    Thank you for answering so promply. But what CD drivers? There is a file named mscdex.exe in the c:\windows\command directory. Do I need other files or this one in another location?

    You need entries in the CONFIG.SYS and AUTOEXEC.BAT file to point to the driver for the CD drive, and MSCDEX, which is the DOS file system handler for CD drives. The easy way is probably to visit a place like AllBootDisks and download one for W95.

    I went to AllBootDisks and downloaded the iso image for Windows 95b which is what is on the computer. Then I used that to make the bootable floppy. When I restart the computer it boots up to a: drive. But I still get an invalid drive error when I try to access the CD rom on drive e:
    How do I put the needed entries into autoexec.bat and config.sys and what are those entries.
    In config.sys there is a line like this:
    DEVICE=cd1.SYS /D:banana

    When I click on autoexec.bat in Windows Explorer like I did with config.sys a box titled Finished - AUTOEXEC comes up with this line:
    MSCDEX Version 2.95 already started.

    Perhaps the CD isn't being assigned to E:. When DOS starts, you should see MSCDEX announce the drive letter assigned to the CD.

    You are right. Dos has assigned the letter r to the drive. Why would it show up in Windows as e: and in Dos as r:?
    This is a little bit confusing. Is there a way to make this the e: drive?

    Thank you very much. It has been a long time since I did anything with Dos and I wasn't very good at it when I did. This will take care of my problem.
    Thanks again for your promptness.

    Sorry, but one more thing. Does this line MSCDEX /L:e go in the config.sys file?

    It goes in the AUTOEXEC.BAT file, you'll modify the one that's already there, since the CD works.

    Now I have Drive e: assigned to the CD-Rom and I can boot into Dos and type in the command to start loading the game but then a message that comes up that says: "This program requires that a mouse be installed. Program aborted."
    There is a mouse and it works just fine in Windows. Now what have I done?
