This article was previously published under Q75169


IBM is shipping their own version of the Microsoft MS-DOS 5 Upgrade called PC-DOS 5.0 Upgrade. It is currently available from software retailers. This is quite different from the Microsoft MS-DOS 5 Upgrade released by Microsoft.


Some of the major differences are as follows:

    Setup: IBM's Setup works basically the same, with some exceptions to the options available. You cannot install to floppy disks, and you must have IBM PC-DOS installed on the hard drive. Only IBM PC-DOS versions 2.1 to 5.0 are supported. You also must boot from the Upgrade to install.
    IBM PC-DOS 5.0 Upgrade has 122-key keyboard support.
    IBM PC-DOS 5.0 Upgrade has Icelandic code page support.
    IBM PC-DOS 5.0 Upgrade ships with Microsoft Mouse Driver version 7.04.
    IBM PC-DOS 5.0 Upgrade includes a utility to convert version 4.0 DOS Shell .MEU files into the current DOSSHELL.INI file.
    IBM PC-DOS 5.0 Upgrade does not include DEBUG.EXE and EXE2BIN.EXE. These programs must be purchased separately as part of the IBM Technical Reference.
    Date and Time of IBM PC-DOS files are 05-09-91 at 12:00p.
    The "IBM PC-DOS Getting Started" manual recommends using SMARTDRV.SYS as opposed to IBMCACHE.
    IBM PC-DOS 5.0 Upgrade includes AUTOCONF.EXE, which will make your original CONFIG.SYS and AUTOEXEC.BAT files compatible with DOS 5.0.
The product included here (IBM PC-DOS) is manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding this product's performance or reliability.
