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)
