[Coco] NitrOS9 question

Dave,
That is good to know.
I know my test boot disk I was using was on the CoCoSDC, but I am using the
standard REL, KRN, and Boot modules. I know that if I stay above $4200 on
my OS9Boot file it works fine, but if I go under $4200 for size it crashes.
Interesting the modules used to boot on the SD card crashes below $4400.
We have some really freaky stuff going on here :P
