I want to try DosBox for the same reason:
-16 bit [DOS] applications like Turbo C 3.1 uses NTVDM.EXE, which makes high CPU usage.
-so if you ever have to use 2 or more 16bit programs at the same time with the native XP dos-subsystem, your PC slows down very much, could be even unusable.
If you have solutions for the native XP/2k Dos susystem's NTVDM.EXE's high CPU usage, post those here. It would help me.
I tried to set the Idle Sensitivity to High, and I tried using the dpakbd.com.
These two solutions, together reduced my CPU usage, but still, if I use Borland Pascal 7 and Borland C 3 at the same time, CPU is too high and the machine is slowed down.
[I must mention that I need this solution for a school, where students learn Pascal, C/C++ and FoxPro with 16bit DOS IDEs]
Thanks
