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.

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?
