IBM is shipping their own version of the Microsoft MS-DOS 5 Upgradecalled PC-DOS 5.0 Upgrade. It is currently available from softwareretailers. This is quite different from the Microsoft MS-DOS 5 Upgradereleased 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.
