I DIDN'T patch per the above referenced TID, created my NSS Volume, and am
getting the Operating System not found symptom.

Can someone point me in the right direction to fix this?

I have tried booting from the cd and install/other options/boot installed
system, and can get the system to boot, but will applying the patch to the
system at this point fix the issue?

Do I need to remove the server from DS and start-over with a fresh build?

Thanks in advance.
