I am wondering, since this hanging problem is related to dosemu's dpmi
implementation, is it possible for me to use another dpmi implementation?
Can I turn off dosemu's dpmi inside dosemu.conf and then run some other dpmi
inside autoexec.bat?
Is this feasible? What other DPMI implementation is compatible with dosemu?
Thanks.

No, that is not possible. DPMI server runs in protected mode, so it has
to be part of dosemu and a server cannot be installed from the v86 task.
It is the same reason why you can't use another 386 EMS manager under
dosemu, because the EMS manager runs in protected mode in order to use
the 386 paging unit.
Also, usually DPMI servers that are not integrated into the EMS manager
will use VCPI to enter protected mode, since the EMS manager is already
running in protected mode and provides a VCPI interface in case another
program wants protected mode. Using VCPI is unfortunately also
impossible under dosemu, not a fault of dosemu but the fault/intent of
VCPI design.

I have attached dosdebug to dosemu when it hangs, and I got the following:
System state: running in real mode while in DPMI
AX=0000 BX=800a CX=0000 DX=0003
SI=874c DI=023a SP=056c BP=c316

CS:IP=0522:0434
SS:SP=c316:05bc
0522:0434 53 push bx
What should I do? Thanks.

Investigating using dosdebug, it seems that the app is in a loop waiting for
something... please help.

I tried to reproduce the problem using the -D9+Mr log.
However, this time, dosemu actually crashed as opposed to
just hang. The complete log is 33M, so I am just pasting
the end of it here. Please let me know if there is a place
where i can email you the complete log.
Thank you for helping me.

Does this program run in a win95 dos box? I haven't any idea how to
interpret what it's doing in the trace. In the dosemu log, it looks
like the program generates a GPF which is not handled for some reason,
which could either be the bug in the program, or the program being
confused by dosemu. Who sells this program? Can you ask them what the
problem is?

Well, the first thing I'm wondering is what int you are inside of in
that trace. Eventually it does iret, but there was never an int that I
can see. Was part of the trace omitted?
The other thing is that you can try patching the conditional jump
immediately after that comparison that never succeeds:
c316:9036 F64408FF test [si+0x8],0xff
c316:903a 7408 je 9044
The op code for jmp 9044 is EB08. This will at least get you past this
while (foo != -1) situation, but it might just loop again or crash
afterwards. You could also try printing the value at the memory
location si+0x8 when you arrive at that instruction to see if it ever
changes.

in dosdebug type:
e c316:903a 75
that will change the "je" to jne. I had to do something similar for
command keen 4, it was hanging in a very similar way.

Are you speaking about during the system features detection (the first
screen)? I have a hang there too, and in fact any similar ID/Apogee
game which has a screen like that. I haven't any idea what it's sitting
there waiting on....

Yes.

The timer interrupt generator is reprogrammed, and the loop is waiting
until the timer interrupt has a counter set to a specific value. dosemu
can't keep up (>100 Hz), and has to catch up. So the program sees the
value increasing by amounts > 1. This means that the counter never reaches
*exactly* the value the program wants to see, it steps over it.
Your /dev/rtc patch may help, but I haven't checked that.

Hi,
Thank you for helping. Okay:
1. I tried e c316:903a 75, and I see the je changed to jne. However, the
app continues to hang inside that loop...
2. I tried e c316:903a EB08, and I see the je changed to or [bi+si], cl .
The app continues to hang inside that loop. However, I think I am not doing
exactly what Ryan wanted me to do though...
3. I tried d si+0x8 10 after the test statement. The value does not
change. I checked it for 4 iterations.
What else can I try?

This should be a FAQ already.
Upgrade your keen! They fixed their loader
years ago, and this was discussed in that
very list (and at IRC) thousand times. There
are several revisions of Keen4, latest ones
do not have that bug at all.

I haven't checked it with those programs either. I'll give it a try and
see what happens.

The flow of execution should be diverted either to or away from the jump
target depending on the value of the zero flag. If nothing changes in
the trace, then I guess you've done something wrong. Note that it is
possible for the program to find another place to get stuck after that.

Um, something didn't work there. Try
e c316:903a EB
e c316:903b 08
But inverting the conditional jump as bart suggested should have at
least gotten you past that point.
> What else can I try?
Asking the vendor what the program is doing at that point so they can
offer suggestions.

Hello,
1. Tried
>e c316:903a EB
>e c316:903b 08
the trace becomes different, but the app still hangs...
2. Also tried using freedos instead of msdos. Same thing...
BTW, the app is actually a client - server app running on netx. Not sure if
this is relevant...
