SYMPTOMS

If a you are using an original equipment manufacturer (OEM) version of DOS that does not correspond to your computer manufacturer (for example, you are using IBM PC-DOS on a Zenith), the Microsoft MS-DOS 5 Upgrade and MS-DOS 6 Upgrade Setup programs may not work correctly. If this is the case, Setup displays the following error message:

UNRECOVERABLE ERROR
ERROR READING FILE SETUP.INI

WORKAROUND

To work around the error message, do the following:

    Use the VER command to verify that the correct OEM DOS version is being used (that is, the DOS that came with the machine).
    If an incorrect OEM DOS version is being used, install the OEM DOS that came with the machine.
    Run the MS-DOS Upgrade Setup program again.
