[Coco] booting OS9 from hard drive

[Robert Gault]

You have not gone far enough with your patching. You will need to change 
the Boot module which is on track 34. The original one is hard coded for 
floppy use. It must be replaced with one that can access your hard drive.

I'm sure that Cloud-9 has documentation on this in the hard drive system 
owner's manual. I think that there may even be a script buried in the 
directories of 40tCD2 for NitrOS-9 that will automate the building of 
the needed boot disk.

Make sure that your boot disk is only 35 tracks not 40, as RGBDOS and 
HDBDOS expect the Disk Basic partition of the hard drive to be in 35 
track segments.
