Hello Windows and AutoCad experts
I got a problem with running Windows 3.0 and AutoCad386 10.0
My problem is after i have run a Windows session all the extended
memory seams to go on holliday because when i run Acad and type
status on the command line i got the ansver that no expanded memory
in aviable so Acad will swap to disk and become slower than if i run
Acad on 8088 machine.
I got a feeling that it is my version of himem.sys cause this problem
or is i all wrong?
I have test the programs on two different machines with the same result.
Machine one configuration
IBM PS/2 mod 55-x31 with 4 Mb ram
version of himem.sys ver 2.60 date 04/05/90
PC-DOS ver 3.30
Machine two
Crown 486/33 (Hawk motherboard) with 8 Mb ram
himem.sys ver 2.60 date 04/05/90
MS-DOS ver 4.01
AutoCad386 configuration
-hwivec 50h
-minswfsize 400000
-swapdefdisk
-swapchk off
-intmap 08h
-vscan 20000
One way to solve it is to run emm386.sys in config.sys and make some
of the memory expanded instead. For me isn't that a god solution
because on the IBM i want to use all the memory both in windows and
AutoCad. My solution this far is to reboot the machine after i have
run my Windows session.
Is there someone who have hade the same problem and if so did you
solve in a better way than i so would i be greatfull if you could
share your results with me.
Tanks in advance.

There is a bug in Windows 3.0! When you exit Windows 3.0, windows does not realse extended memory so every program you run after that will not have any extended memory free to use (This answer was told to me by guy at microsoft, they will fix it in version 3.1). So you must reboot again to make it free! // Gunnar =============================================================================== Gunnar Dahlstrom Chalmers University of Technology Div.

They have released a backward compatible upgrade for their last version (which autocad 10 & 11) use, that fixes MicroSoft Windows 3.0 problem. The patch is available on compuserve or should be by now, from you autocad dealer. A second fix to this problem would be to buy and use the new version of Quarterdeck's Qram, which is now reportedly fully windows 3.0 compatible, and use that in place of the windows memory drivers in the system. al -- Al.
