[Coco] CocoSDC first time startup

[Bob Devries]

Gene,

If you have built the latest NitrOS9 using "make dskcopy" then there 
should be a file nos96309l2v030300coco3_cocosdc.dsk in the dsks 
directory. You can put that on the SD card (but make its name 8.3). I 
created a file called startup.cfg with:

0 nitros9.dsk

Then at the coco3 screen type DOS, and it will start nitros9. You can 
then access /sd0 (aka DD).

Repeat for /sd1 but with a different file of course.
