Using Uninstall on an OS/2 System (73601)
The information in this article applies to:
• Microsoft MS-DOS operating system 5.0
This article was previously published under Q73601
You can run the Microsoft MS-DOS 5 Upgrade Uninstall program on
systems that have MS OS/2 version 1.0, or IBM and MS OS/2 1.1 and later
versions. However, if you install MS-DOS 5.0 over IBM OS/2 1.0, you
cannot run the Uninstall program.
You can work around this by renaming the IBM OS/2 1.0 system files
IBMBIO.COM and IBMDOS.COM, so that Setup does not confuse them with DOS
If you run the Uninstall program on a system that had OS/2 on it
before the upgrade, running CHKDSK may show some lost extended
attributes. This happens whenever a file that had extended attributes
under OS/2 was altered under DOS before you ran the Uninstall program.
