[Coco] CoCoSDC under NitrOS9

[David Ladd]

You can go up to just slightly lower than 2GB on the CoCoSDC.

The firmware in the CoCoSDC's MCU to 2GB files.

So with NitrOS-9 you just need to make sure that the boot/kernel track
starts at LSN#612.

Because a lot of the older OS-9 3rd party disk utilities though aren't
always compatible with cluster sizes over 1 going over a 127MB HDD image
might prove to be a compatibility nightmare if you aren't careful though.
One of the reasons on any of the HDD images I make for NitrOS-9 I don't go
over 127MB in size just for the sake of not running into issues later.
