[Coco] NitrOS9 L2 CoCo 3 question: Display settings/modifications

[Brett Gordon]

I've hand merged my own diddled (with bad CRC's) modules into OS9Boot with
no problems.  Nitros9 has boot-up CRC checking off by default.  I turned it
on once, and the boot up was quite a bit slower.  I'm not sure what happens
to after loaded modules.
