RE: Sorry, does not tell much -- some additional info

Hi, I just wanted to add some details:

George has tried running TC after installing
- no memory driver
- only an XMS driver
- both XMS and EMS drivers
- all of XMS EMS and DPMI drivers (DR emm386 with DPMI=ON option)

All on an 2027te kernel, which ran other programs okay (apart from
CSAP, but CSAP crashes for me, too, at least in DOSEMU with a diskimage,
I did not dare trying in DOS, as CSAP modifies directories).

All of the above attempts just ended in TC crashing right away.
DPMIINST is a tool to patch DPMI16BI.OVL according to the current
configuration (with respect to questions such as "how do I access the A20?"
and "Is DPMI available / is the CPU in real mode?".
DPMIRES is meant to be used to preload the DPMI of TC, but if not used,
TC will just load the DPMI driver itself.
My hope was that if the DPMI driver of TC is broken, using another DPMI
like the DR emm386 DPMI=ON one would fix the problem, but it did not.

Here some lines from MY dosemu.conf for your inspiration:

With those settings I can run:
- Descent (no sound)
- Jazz Jackrabbit (soundblaster sound)
  (hm, just crashed when trying to enter a level, oops)
  (used killall -9 dosemu.bin ...)
- Raptor (no sound)
- DJGPP
...

So generally, things run fine in xdosemu, even with protected mode :-).
I use xdosemu 1.0.2 with still kernel 2024 (the one that comes with that
version of xdosemu). http://www.dosemu.org/ - by the way, runs completely
in unprivileged mode. Please forget about that old "legend" that it should
run as root.

PS: In plain DOS (2027te), Descent did only run with DR emm386 DPMI=ON.
This is why I thought that the same trick may help George with TC.
But as I only have TC 2 / TC++ 1, not TC++ 3, I did not test if it would
run on my system - only George did the tests involving TC++ 3.
