[Coco] NitrOS9 booting sequence

[Dave Philipsen]

Thanks, Bill.  I believe that the padding is correct.  I did it manually 
and was one byte off at first and the whole thing failed much earlier.  
When I corrected the padding problem I could see that the entire OS9Boot 
file got loaded in.  I'm going to look at grfdrv, Init, and Sysgo on the 
next try.

I'm also trying to accomplish this with native tools under NitrOS9 instead of using the Toolshed and Lwtools packages. So, today I was able to create a boottrack file and svdgen a disk.  When I try to boot it the screen shows all of the modules loaded through Clock2 and then at the end it prints  "i2xo*X" just before the boot fails.  I'm guessing that something is still missing on the boot disk.  I have an OS9Boot file, a sysgo file, and a CMDS directory with just "shell" in it.  What am I missing in order to complete the boot?
