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:
 * 1) Create a set of working disks.

For more information about how to create working disks, see the section titled &quot;Installation on Floppy Disks&quot; in Chapter 2 of the version 5.0 &quot;Microsoft MS-DOS Getting Started&quot; manual.
 * 1) After you create the working disks, back up all of your current MS-DOS files by copying them to another directory or disk.
 * 2) Remove any memory resident programs from your AUTOEXEC.BAT file.
 * 3) Insert Disk 1 - Setup in drive A.
 * 4) Type a:setup /m.
 * 5) When Setup is finished, press ENTER to restart your computer.
 * 6) 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 &quot;Incorrect DOS Version&quot; error message will be displayed if the previous MS-DOS nonsystem file is executed.
 * 7) Compare CONFIG.SYS and AUTOEXEC.BAT with CONFIG.NEW and AUTOEXEC.NEW. Make necessary modifications.
 * 8) Restart the computer. Make sure there is no disk in the floppy drive.
