SYMPTOM:

If EMM386.EXE is loaded, machine may hang or reboot when trying to
run a program which uses the "DOS 4GW Professional" memory extenders;
Error message "VCPI server has reprogrammed the interrupt controller"
may occur with games which use the "JEMM" memory extender.  These
extenders are used in many types of programs, especially games. 
Games Novell is aware of which use these extenders are:

DOS 4GW:
Gabriel Knight: Sins of the Fathers (by Sierra)
Sim City 2000 (by Maxis)
Raptor (by Apogee)
One Must Fall (by Epic MegaGames)
Doom

JEMM
Privateer (by Origin)
Strike Commander (by Origin)

There are many more programs, both games and non-games, which use
these extenders.  Note that not all programs give the same type of
problems.  In addition, some may not have problems with specific
EMM386 configurations.

SOLUTION:

Obtain the update file D70U08.EXE (or later file).  This contains
(among other files) a new EMM386.EXE which will allow DOS 4GW and
JEMM programs to run.  To run one of these programs, the user should
first give the following command at the DOS prompt.

EMM386 PIC=ON

After exiting the program, give the command

EMM386 PIC=OFF

If problems still occur, try turning DPMI OFF at the command line, or
make sure that neither DPMI nor MULTI are set ON with the EMM386
device line in the CONFIG.SYS file.
