I've been trying to get programming information out of Intel for months now. I have a development kit that we use for our own i960Rx boards and would work dandy with this board, I just need a few more bytes of information to write a board support interface.
I have a case # and everything. If anybody can shake loose the information I need, I can get the ball rolling.

And a correct guess, sorta.
Actualy, the i960Rx has a few mode pins that tell it what to do at reset time. The options are:
start the processor and retry all the configuration cycles, start the processor and pass all the configuration cycles, hold the processor and pass configuration cycles.
The last 2 leave the bridge acting like a normal bridge. The first allows the processor to first take over and mark some devices and private before allowing the BIOS through the bridge.
