[Coco] NitrOS9 booting sequence

[Dave Philipsen]

That was exactly it.  Thanks! When I placed grfdrv in the cmds directory 
it booted through fully.  I am still booting with dw and the REL, Boot, 
and Krn modules are all 'stock'.  This was just an experiment in 
assembling them together manually and creating a boot track file.  The 
next step will be to assemble each one of the modules from source using 
asm and then try it all again.  After that I can try some mods to Boot 
that will load the system from SD card.
