Say David is there a way to run ACAD 11 with windows 2000?
I tried to run in a DOS window and get this:
Par Lap err 35: The 386 chip is currently executing in vertual 8086 mode under the control of another
program. You must turm off the other program in order to use 386|DOS-Extender to run in protected mode.
Cab, I am not sure that it is possible. While the Pharlap 386 Extender would work on R12, it would only work on R12c3. It would not work with R12c2 or prior unpatched versions.
You are on the right track for R12 though..
system.ini
[386Enh]
device=pharlap.386
Copy the pharlap.386 executable to the system folder, leaving the one in the AutoCAD folder.
To my knowledge it is not possible with the older versions, but XP might offer some joy with compatability mode.
