Okay, made a program that works fine putting an image to the screen pixel at a time. when I try to put a simple i++ into a for loop to make the image display right (320/200 onto a VBE 2.0 640/480) I get a general protection error.. ON THE simple i++ command why would it do this? is DPMI just that touchy? And when programming under DPMI is there a memcpy that works? I've tried the dosmemset and memcpy and BOTH give me a general protectino error or REboot my machine. (copying from a memory block created with malloc over to a linear frame buffer)
