This is a (still experimental) framework to run BIOS code in a virtual
8086 machine. Ifff it works, it is much easier and more elegant than
going to real real mode:
-simpler code
-no need for "identity" memory mappings
-easy passing of buffers for bulk data to functions
-some more control
There is no interrupt support ATM, and it lacks a function to access
random virtual memory of the VM. MP issues to consider.
