I forgot to mention it provides Virtual Memory too. The author writes a small DOS program that requests memory via XMS. Then he takes a PC with 8 MB RAM, replaces "KRNL386.EXE" with COMMAND.COM, so that when the PC starts, you get COMMAND running on VM0 inside a 32-bit VMM world. He runs that DOS program, and magic! The program is able to gather 12MB of XMS memory. Aitor
