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.
