Okay, the Rialto stuff is taking more and more shape.

I was able today to take the bare PCIe BIOS and put the rialto config block + data into it, no other motifications. The card boots, comes up as the X700SE it was flashed with and even reports a VIVO card (though the Rage Theater is not present).
This is just awesome. The config blocks from my HD3450 and X1950GT work on the X700 as well.

So I'm pretty certain now about Rialto being pretty universal.

So today I started going further and started to rip apart the sacrificial HD3450 AGP. Goal is to remove the GPU and memory and maintain the Rialto on it. Record behavior. Then I'll add a PCIe slot and put an HD3450 PCIe into it..

Long way to go, but I'm very excited..

I can see the rialto chip alone enumerating in windows without the GPU - so the bridge is alive and well. Tomorrow there will be some annoying handwiring.
