IBM PS/1 System Menu Unavailable After MS-DOS 6 Upgrade PSS ID Number: Q102815 Article last modified on 08-11-1993 PSS database name: O_MSDOS

6.00

MS-DOS

= SYMPTOMS =

After you upgrade to MS-DOS 6.0 on an IBM PS/1 machine, the System menu (sometimes referred to as the four-quadrant screen) is unavailable or does not work correctly.

= CAUSE =

Many PS/1 machines were purchased with IBM DOS 4.0 and a System menu program preinstalled. When you upgrade to MS-DOS 6.0, this menu program (which allows PS/1 users to work at an MS-DOS prompt, in Microsoft Windows, and so forth) is lost.

= RESOLUTION =

IBM has a patch available to correct this problem. The patch is available from the IBM Bulletin Board Service (BBS) and America Online. The IBM PS/1 BBS number is (404) 835-8230. The name of the specific file is 4QUADMS6.EXE; it is in a self-extracting compressed format.

= MORE INFORMATION =

The PS/1 is manufactured by IBM, a vendor independent of Microsoft; we make no warranty, implied or otherwise, regarding this product’s performance or reliability.

For more information, call the IBM Support Center at (800) 426-3333 or IBM PS/1 Support at (800) 765-4747 or (404) 835-9116.
