MS-DOS

The information in this article applies to:
- Microsoft FoxPro for MS-DOS, versions 2.0 and 2.5
SYMPTOMS
Upon exiting Extended FoxPro for MS-DOS, the "FoxPro/LAN 2.0 - Normal
shutdown" message is displayed, and the system either hangs or reboots.
This problem may occur on every second exit of FoxPro, or the problem may
appear to be random.
CAUSE
This problem is caused by a combination of the following:
- There are HIMEM.SYS and DOS=HIGH statements in the CONFIG.SYS
file, but you are not loading a memory manager such as
EMM386.EXE.
- You are running Extended FoxPro while Novell network drivers are
loaded. (The problem occurs whether FoxPro is on the server or
on the workstation.)
- You are loading any of the following while in Extended FoxPro: a
printer driver, a library file, or a BIN routine.
The workstation will reboot or hang after exiting FoxPro every second time
that all three of the above conditions are met. This problem will never
occur on the first exit.
STATUS
Microsoft has confirmed this to be a problem in FoxPro versions 2.0 and 2.5
for MS-DOS. This problem was corrected in FoxPro version 2.5a for MS-DOS.
RESOLUTION
Any one of the following workarounds will solve the problem:
- Remove DOS=HIGH from the CONFIG.SYS file.
- Leave DOS=HIGH in the CONFIG.SYS file, but add a memory manager
such as EMM386.EXE.
- Issue a RUN command, such as RUN>NUL DIR, before exiting
Extended FoxPro.
- Run Standard FoxPro instead of Extended FoxPro.
- Upgrade to FoxPro version 2.5a for MS-DOS or FoxPro version 2.5
for Windows.
- Edit GENPD.APP to use DRIVER.PRG instead of DRIVER2.PLB. (This
will solve the problem only if DRIVER2.PLB is the only library
file being used. If you are loading another library or a BIN
routine, one of the remaining workarounds will be required.)
To modify GENPD.APP to use DRIVER.PRG instead of DRIVER2.PLB, do the
following:
- Open the GENPD.PJX file in the GOODIES\PDRIVERS subdirectory.
- Edit GEN_PD.PRG.
- From the Edit menu, choose Find, and search for "DRIVER.PRG".
- Delete the asterisk from the following line:
* (_PDRIVER = "DRIVER.PRG").
- Place an asterisk at the beginning of the next command line:
(_PDRIVER = "DRIVER2.PLB).
- Close GEN_PD.PRG, saving the changes, and rebuild the project
and application. (Note: Be sure to save GENPD.APP in the
FOXPRO2 directory or in the directory returned by ?_GENPD.)
