SUMMARY

If you do not have enough free space to install Microsoft MS-DOS 5 or later Upgrade even after removing unnecessary files, you can perform a minimal installation. A minimal installation does NOT do the following:
    • Expand and copy nonsystem files directly from the upgrade disks to your hard disk.
    • Copy your previous nonsystem files to the OLD_DOS directory.
A minimal installation creates the following:
    • CONFIG.NEW and AUTOEXEC.NEW files
    • MS-DOS version 5.0 or later system files (IO.SYS, MSDOS.SYS, COMMAND.COM) on the hard drive
    • An OLD_DOS directory containing only a README.NOW file

MORE INFORMATION

To perform a minimal installation, do the following:
    • Create a set of working disks.

    For more information about how to create working disks, see the section titled "Installation on Floppy Disks" in Chapter 2 of the version 5.0 "Microsoft MS-DOS Getting Started" manual.
    • After you create the working disks, back up all of your current MS-DOS files by copying them to another directory or disk.
    • Remove any memory resident programs from your AUTOEXEC.BAT file.
    • Insert Disk 1 - Setup in drive A.
    • Type a:setup /m.
    • When Setup is finished, press ENTER to restart your computer.
    • Because you have the working disks of MS-DOS 5.0, you can selectively copy nonsystem files of MS-DOS 5.0 to the previous MS-DOS directory. Do not mix the previous MS-DOS nonsystem files with the new ones in the same directory. An "Incorrect DOS Version" error message will be displayed if the previous MS-DOS nonsystem file is executed.
    • Compare CONFIG.SYS and AUTOEXEC.BAT with CONFIG.NEW and AUTOEXEC.NEW. Make necessary modifications.
    • Restart the computer. Make sure there is no disk in the floppy drive.
