SUMMARY
=======

Compaq DOS version 2.11 is equivalent to MS-DOS version 2.1. Microsoft MS-DOS 5
or later Upgrade requires MS-DOS 2.11 or later to upgrade DOS to version 5.0 or
later. The following error message is likely to occur when upgrading from Compaq
DOS 2.11:

  YOUR VERSION OF DOS CANNOT BE UPGRADED BY SETUP

MORE INFORMATION
================

You may receive this message when installing to the hard disk or to the floppy
drive. To upgrade to MS-DOS 5.0 or later, use the following steps:

1. Install MS-DOS 5.0 or later on another computer by typing "setup/f" (without
  the quotation marks).

2. Boot the original computer using the startup disk.

3. Verify that the hard disk is functional under MS-DOS 5.0 or later (the CHKDSK
  [no /f] command will verify proper disk access by the current DOS version).

4. Use the SYS command to copy the system files onto the hard drive.

5. Copy the MS-DOS 5.0 files or later from the working disks to the DOS
  directory on the hard drive.

6. Restart the computer from the hard disk.
