MS-DOS 5.x and later Setup runs from only drive A or B. If you have an external floppy drive that is not recognized as drive A or B, you need to either reconfigure you hardware or run MS-DOS Setup from your hard drive.


To run MS-DOS Setup from the hard drive:

    Create a directory on the hard drive. For example, type md c:\temp at the MS-DOS command prompt and then press ENTER.
    Copy all of the files from the MS-DOS Upgrade disks to the temporary directory. For example, insert the first disk into floppy drive A and type the following at the command prompt:

    xcopy a:*.* c:\temp

    Repeat this for all disks included in the MS-DOS Upgrade package.
    Change to the directory that you created in step 1. For example, at the MS-DOS command prompt, type the following commands, pressing ENTER after each one.

    cd temp

    At the command prompt, type the following:


    This command starts the MS-DOS Setup program.
    After Setup has completed and rebooted your computer, delete the temporary directory and the files.
