Well, it worked! Thanks to all for all the great info.
Here's the details:
V4 Iop - box dated 5-11-00, rise cpu, bios gooed all over, no clipped pins or security torx
Drive - 2.5" seagate ST9816AG dolly'd with qnx image
I just followed the recipe at http://www.linux-hacker.net/cgi-bin/UltraBoard/UltraBoard.pl?Action=ShowPost&Board=verytech&Post=86&Idle=0&Sort=0&Order=Descend&Page=0&Session=
The partitions looked funny (2%, - , 2%, 10%) but it worked! "nothing but net!"
No funny black screen problems, no cracking out the goo, just an easy flash and go....
thanks! and good luck all!
