New user here.  Feel like I saw this discussed in a doc somewhere when I 
started this project, but now I can't find it.  Apologies in advance if this 
is covered...

System is a 7500 long ago upgraded with a 604 from a 9500.  Works fine under 
OS9.  I applied the patch to System Disk, set to boot to OF, and hit save.  
The system comes up and seems to sync video just fine, but I only get the 
white screen.  No text, no prompt.  I have not attempted going over serial as 
I'm anticipating needing X on this system and would prefer to get this sorted 
out.  Any suggestions no what to try next?

Thanks-
Rich Noonan
