If user setup a memory window to access "more than 4GB", the <pointer> is still 32-bit ? Am I correct ? My goal is to allocate one memory buffer and its "physical address" is beyond 4GB. Then this address will be set to H/W register for DMA transfer...(Besides CPU can access this buffer, too) Thus I have to get more than 32-bit pointer and then assign it to H/W... I do not know if CWSDPMI+DJGPP can do this kind of task... Thanks !
