You probably should put your copy of Peter Nortons "Inside the IBM PC" (dated 1983) back into the shelf. MS-DOS 2.11 has recently been superseeded. :-D No kidding: You *are* using plain DOS here? Windows ( later than WinME even in the dos box) will not allow you to access the hardware direcly.

I got my copy of that book still sitting on the shelf above my PC at home. You never know when you need to look up some detail about the A20-Gate again! :laugh:

Wouldn't that require bypassing the HAL?
