SUMMARY
=======

After you have installed the MS-DOS 6.0 upgrade, the Extended (32-bit) version
of FoxPro (FOXPROX.EXE) may not load or may go into demand paging.

This behavior occurs because the upgrade process changes the AUTOEXEC.BAT and
CONFIG.SYS files.

To resolve memory-related problems after the MS-DOS 6.0 upgrade is complete,
check the following items:

- If SMARTDRV.EXE is loaded in the AUTOEXEC.BAT file, it may reduce the amount
  of available memory on a "minimum requirement" configuration.

- In the CONFIG.SYS file, the FILES statement is often lower than it was
  earlier.

- In the CONFIG.SYS file, the BUFFERS statement is modified or removed. It may
  need to be set in the 20-40 range.

- The DEVICE = EMM386.EXE line includes HIGHSCAN option. (Remove if you are
  having problems.)

- The DEVICE = EMM386.EXE RAM or NOEMS is changed from prior setting.

- The DEVICE = EMM386.EXE may require NOVCPI option.
