This I can do albeit in a limited fashion.

The "without a reboot" is an interesting challenge. For one, you have to deal 
with cleaning up the virtual floppy space while executing out of it. Like 
closing the hatch door on the way out; reboot punts this problem. Another is 
the cmos and hook tweaks needed to redirect the original DOS to the virtual 
disk need to be gone so the hd os loader doesn't trip on them.
