[sco.opendesktop] MS-Windows 3.0 under Xenix and Unix

drolet@drolet.CAM.ORG (Jean-Jacques Drolet) (03/08/91)

I am trying to install Microsoft Windows 3.0 under two different envi-
ronments, namely

1) SCO Xenix System V/386 2.3.2 with VP/ix 1.01;
2) Open Desktop 1.0 (SCO UNIX System V/386 3.2 with DOS Merge).

Up to date, I have had very little success. Any help would be
greatly appreciated. As I don't yet receive sco.opendesktop, please
post your replies to comp.unix.xenix.sco or mail them to my
Internet address. Thanks a lot.

According to SCO support, MS-Windows 3.0 can not work under VP/IX since
it requires 286 or 386 protected mode and VP/IX provides only virtual
8086 emulation.

That's true. Out of the box, Windows 3.0 can't run under VP/ix. However,
if you patch the code that determines on which processor Windows is
running so that Windows believes it is running on a 8086, you can
run Windows under both VP/ix and DOS Merge (SCO Open Desktop). I have
the patch here; anybody interested can write to me. If there is sufficient
interest, I will post it.

This is not correct.  Microsoft Windows 3.0 will run *in real mode
only* on SCO UNIX if you:  (1) are running SCO VP/ix 1.2.0 and (2)
have installed Support Level Supplement (SLS) unx268.  SLS unx268
won't install on SCO MPX or on the SCO 286 or 386 XENIX Operating
Systems.

MS-Windows 3.0 won't run _in protected mode_ under VP/ix, in much
the same manner as it won't run in protected mode on a 8086-based
machine.  SLS unx268 simply makes sure that Windows "thinks" its
installing on an 8086-based machine, and Windows takes care of the
rest.
