To be able to even run the bug fix I need to start in "Normal MS-DOS mode"
and then run win.com

But since I do NOT have any conflicts in DOS I CAN blaim Windows for this!
All of a sudden several IRQs are used fror various tasks - but neither the
BIOS nor DOS will see these components.

And why is it then not an OS? This time your logic eludes me.
Besides, wasn't CP/M a UNIX clone?
Anyway I really doubt that an OS is a program that constantly keeps your
computer busy wheter you use it or not. None of the information I've read
has stated that DOS isn't an OS.

But why do anything when nothing is supposed to be done? IMHO that's very
useless, and I doubt anyone will disagree with me on that.
