[Coco] NitrOS-9 ROM Pak ?

[Robert Gault]

Roger,
Here is a specific example. Take a normal DOS1.1 ROM and change two 
bytes at $C0E5 and $C0E6 to $DF02. When that ROM starts, it will 
immediately issue the DOS command and boot OS-9 from a floppy.

You can test this with a Coco3 by turning on the unit and issuing the 
following:
POKE&HC0E5,&HDF
POKE&HC0E6,&H02
EXEC&HC002

You were probably thinking of having the kernel in the DOS ROM. With a 
Coco3, the SEB will patch the RAM image of the ROM and most likely trash 
the kernel.
