SUMMARY
=======

The chart below shows which versions of MS-DOS can be run with Windows.

If the error "Unsupported DOS version" occurs, check the Windows version and the
MS-DOS version against the chart below. It is also important to verify that the
MS-DOS version being used is the one recommended by the hardware manufacturer
and not an OEM version from another hardware vendor (for example, IBM PC-DOS on
a clone machine).

MS-DOS version 3.0 or later is required to run any version of Windows 2.03
through 2.11. MS-DOS version 3.1 or later is required to run Windows versions
3.0 and 3.1.

        does not work correctly with IBM PC-DOS 4.0

   (b)  If dated 9/7/88 or later, Yes; if not, No

   (c)  Must have SETVER.EXE loaded in the CONFIG.SYS file
        to work correctly with MS-DOS 5.0

"Windows/286" in the table above includes Windows/286 and all Microsoft run-time
versions sent out with Microsoft products (Excel, Word for Windows, and so on).

This data is based on MS-DOS version numbers. An OEM DOS product with the same
version number may not work correctly. (In these cases, an OEM DOS upgrade may
be required to work with Windows).
