VSI VMDK issues

[Single Stage to Orbit]

So I finally got around to playing with the VDMK file VSI sent me a
couple of days ago.

VirtualBox wouldn't boot the VDMK as it was an unsupported format. WTF?
A quick examination of the VDMK file indicated it was raw disk image so
I converted the file to a VDI and tried to boot it. It worked. But
now...

It keeps throwing a BUGCHK on boot and dropping me back at the VSI boot
screen.

Figured it out eventually :-D All it needed was the controller set to
AHCI mode. Yay. Here We Fkn' Go!
