SYMPTOMS
If you do not update your Windows 95 Startup disk (also known as theEmergency Boot Disk) either when you install Microsoft Plus! for Windows95, or when you run DriveSpace 3, you may not be able to start yourcomputer with the Startup disk.
CAUSE
The Startup disk has not been updated for DriveSpace 3. Therefore,DriveSpace 3 compressed volume files (CVFs) cannot be mounted or repaired.
RESOLUTION
If Windows 95 starts normally, you can create a new Startup disk withupdated files by following these steps:
  1. In Control Panel, double-click the Add/Remove Programs icon.
  2. On the Startup Disk tab, click the Create Disk button.
If you cannot start Windows 95 normally, you must replace the Scandisk.exeand Drvspace.bin files on the Startup disk with updated versionscompatible with DriveSpace 3. To do so, follow the steps in theappropriate section below.

Using the Microsoft Plus! CD-ROM

NOTE: If you cannot access the CD-ROM drive, the real-mode drivers for theCD-ROM drive are probably not being loaded in the Config.sys andAutoexec.bat files. You must load the appropriate drivers for the CD-ROMdrive to function.

For additional information, please see the following article in theMicrosoft Knowledge Base:
135174 Cannot Access CD-ROM Drive in MS-DOS Mode
Or, if you have not started Windows 95, view the Config.dos andAutoexec.dos files with a text editor. If they exist, copy the lines forthe CD-ROM driver and Mscdex.exe to the equivalent Config.sys andAutoexec.bat files.

When you have finished updating the Startup disk, remove these lines fromthe Config.sys and Autoexec.bat files.

To update the Startup disk, follow these steps:
  1. Boot your computer to a command prompt, and then insert the Startup disk in drive A.

  2. Insert the Microsoft Plus! CD-ROM in the CD-ROM drive.
  3. Type the following command, and then press ENTER
    copy <cdrom drive>:\win95\*.* a:
