wine users - Sep 2002 - Abacus DOS problem Lock Selector

A lawyer in California is trying to change to linux. In CA, there are a 
number of programs required by the courts, and so far none are ported to 
linux at any price.  His reason for wishing to change has to do with the 
fact that Microsoft now controls his access to his own files, and he finds 
this unacceptable.

I tried one of his apps, an old DOS version of Abacus.  Using the WINe with 
Redhat 7.3, I get an error:

Warning: unprotecting the first 64KB of memory to allow real-mode calls.
          NULL pointer accesses will no longer be caught.
fixme:int31:INT_Int31Handler lock selector not supported
err:int31:INT_Int31Handler int31: unknown/not implemented parameters:
int31: AX 0a00, BX 0005, CX 0000, DX 0000, SI 2bb2, DI 2bb2, DS 0267, ES 0267
wine: Unhandled exception, starting debugger...
err:seh:EXC_DefaultHandling Unhandled exception code 80000102 flags 0 addr 0x43

After some Google research, I found DOS PROTECTED MODE INTERFACE listing, 
which says:

DPMI 0.9 + Lock selector Int 31/AX=0004h.

I tried all the versions for wine with no different result.

I am betting it is also missing Unlock selector 0005h.

I downloaded all monthly summaries of this mail list from Feb. thru part of 
August, and did word searches with Open Office. No luck.

I have looked at dosemu, but simply do not relate to what they are saying 
about building a .dexe file,
sigh.

Any ideas at all?

Normal for DOS apps.

Locking memory was only necessary in real DOS because paging out critical
interrupt handlers and such under DOS was a recipe for disaster. It is not
important under a virtual "DOS box" like the one Wine implements.

0x43
Now this is what shouldn't happen. 80000102 is EXCEPTION_VM86_STI, which
is a very normal condition raised by __wine_enter_vm86 (and the DOSVM
event handling and signaling system), it should have been caught and
handled by the DOSVM subsystem in winedos (by dispatching interrupts).
Then again, if your app is a DPMI app, perhaps something does not handle
this right once the app enters protected mode. (You could ask the last
developer that I remember working on DPMI, Jukka Heinonen, I doubt I'll
have much time to fix a not-so-minor problem like this myself.)
