Using an Enhanced Display Mode with QEMM or 386MAX

ID: Q86913

The information in this article applies to:

Microsoft FoxPro for MS-DOS, versions 1.02 and 2.0

To run FoxPro in an extended display mode (more than 25 lines) with either the QEMM or 386MAX extended memory manager, it is necessary to exclude the memory area used by the video board and its device driver.

Modify the corresponding line in the CONFIG.SYS file, as follows:

   QEMM:     DEVICE=QEMM.SYS RAM X=A000-C7FF
   386MAX:   DEVICE=386MAX.SYS EXCLUDE=A000-C7FF

Although the address range A000 through C7FF should be appropriate for most VGA video boards, consult the documentation for more specific information.

The QEMM and 386MAX products included here are manufactured by vendors independent of Microsoft; we make no warranty, implied or otherwise, regarding these products' performance or reliability.
