Paul, the PCI 2.1 specification allows for 66mhz , 64 bit data paths. As you mentioned, only DEC is doing this AFAIK. Intel has mentioned that AGP is a superset of this spec. It will perform these 2.1 operations, but only with a 32 bit bus. In addition, it provides for 66mhz "double pumped" operation which allows for 132mhz transfers. The net effect of (32 bits x 132mhz) = (64bits x 66mhz) but with lower pincount. As for AGP, as it is currently implemented, AGP is actually a port, even though it looks like a bus. It allows for only 1 device. There is no allowance for multiple devices to arbitrate for the port. I don't know if AGP2 will change to a bus. Could the current AGP port be used in a server for non-graphics applications? Hey, that's a good idea! I wonder if Intel is looking into this? Cheers, EP
