I posted a similar question not too long ago, so it's likely that you're having the same problem that I had. Anyway, what I was doing wrong was using EMM386 with its default 256 kb of expanded memory, so when go32 runs, it uses the expanded memory instead of extended memory. As a result of the small amount of memory (<256kb) it does a lot of swapping and slows down. When you're using a Windows dos box, Windows provides all the DPMI memory that is available, which is about 2-2.5 MB looking at your configuration of 8 MB, also depends on what you've got running at the same moment. I just got rid of EMM386 and loaded everything low but I now have a lot more extended memory for go32 so gcc compiles faster. Hope this helps. -- John Wong | Tel : 905 5535 Elec. & Comp.
