PROBLEM: Program using digitized voice for Sound Blaster/MCV does not work.

CAUSE: It is due to the hardware differences in interrupt handling
between the AT bus machine and the Micro Channel machine. Therefore,
Sound Blaster program which is designed for AT bus cannot be used on
PS/2* machine directly

REMEDY: A modification can be made to the software by using the file
FORPS2.EXE which is found on the Sound Blaster/MCV distribution
diskette. This can be used to solve the problem.
Format: FORPS2 [filename] *.?

I can't findt it, but last night, I ran over a snippet that FORPS2.EXE
was aimed at the drivers/programs NOT written IAW the SB hardware
programming guide. How exactly, I dunno.

PROBLEM: Software for SOUND BLASTER don’t run, but TEST-SBC works fine
for digitized sound.

CAUSE: Due to hardware difference between PS/2* & PC interrupts must be
handed by software differently. Some early versions of software for
SOUND BLASTER might have problems running on MCV.

REMEDY: If these software uses routines contained in SOUND BLASTER
Developer Kit, FORPS2.EXE offers a solution by modifying the portions of
codes that handle interrupts. For software that does not use SOUND
BLASTER Developer Kit, there is no solution. You have to wait for the
software upgrade from the publisher.

IMPORTANT !
We have taken all necessary precautions and to ensure that the code
modifications made by FORPS2 does not affect the original software
performance. However, we strongly advise you to back up your software
before running FORPS82.

You can find the Program, FORPS2.EXE in the Disk 1. To run it, go to the
directory containing FORPS2.EXE,and enter

> FORPS2 path\*.*

where path is the directory containing the software to modify. “*.*”
means all files are searched for the specific codes.

Truly what's wrong with the majority of DOS games that don't work with Sound Blaster compatible chipset MCA cards. Not written to handle MCA IRAQs and DMA architecture.
