[Coco] NitrOS9 booting sequence

[Bill Pierce]

Dave, if I'm not mistaken, you'll need GRFDRV in the cmds dir as well. Grfdrv is loaded after sysgo and before the shell (I think).
Also, I would have a "startup" that loads and links the shell. Any cmds used in the startup script also need to be in the cmds dir.
>From the error code you listed, it's showing "Path Not Found" on the sysgo load.
For the explination of the boot error codes, read this:

I am assuming David, you have the standard descriptor/drivers in the boot file? 
If yes, it sounds like the padding on REL/BOOT & KRN might be off.  The vectors
at the end of KRN need to be specifically at $FFF0.  If that checks out I would
look at Init and Sysgo.

out I am trying to make some modifications to the REL, Boot, and Krn modules in
order to get the CoCo3 FPGA booting directly from the SD card without help from
DW.  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?
