Yes you can. You can debug your PMODE/W programs in exactly the same manner you would debug a DOS/4GW program (using the /TR=RSI switch of course). You cannot, however, debug programs which have been compressed using PMWLITE. You also cannot debug PMODE/W programs that do not run under DOS/4GW. Why can’t I access more than 16 megs of memory under my VCPI server when there is more than that available in my system? You must increase the maximum number of VCPI page tables PMODE/W will manage using the PMWSETUP program. Each page table you add will give you another 4 megs of memory (provided that it is physically available of course). Why can’t I map more than 4 megs of address space of a physical device using DPMI function 0800h? You must increase the maximum number of physical address mapping pages in PMODE/W using PMWSETUP. How come PMODE/W takes a little while to load under EMM386? PMODE/W allocates all of its extended memory pool during initialization whereas DOS/4GW allocates memory
