In reinstalled VCC 1.14 and it came up with Disk BASIC 1.1. Typing
DOS253 generated an error. At that point, I assumed the ROM was not
patched. :) If there's a switch for getting RGBDOS booting instead,
I guess I overlooked it.

I really wasn't looking for RGBDOS, but if it's built into VCC, then
I guess I'm stuck into using it in order to boot into the NitrOS-9
.vhd ? :) Ofcourse, I'm aware that you're the maker of RGBDOS but
what about the hundreds of people not on this list who has downloaded
VCC. Their natural instinct is to go to the author for support, so
you *might* want to give a heads up to the crowd so he won't be
swamped with questions. If it's in the docs, that should help.

Anyway, great job to whoever is responsible for VCC booting up a
NitrOS-9 "hard drive" with the Sierra games on it, and plenty of
space to copy in all of my OS-9 .dsk images and much more. This is
what I was looking for in a simple way but nobody could get it right
until now I guess.
