Let's Code MS DOS 0x29: Extended Memory (XMS)

In the previous episode we learned how to use Expanded Memory even down to the original IBM PC. From the IBM AT and other 286 machines onwards we can use Extended Memory instead. It doesn't require any additional hardware and allows you to use more than 640K of memory in real mode MS DOS programs.
