Right, it seems to be not talking on the network.

I have directly connected a machine to the machine that should be doing 
the aoe broadcast and I run tethereal on it and it sees nothing.

I am thinking maybe my hardware is messed up somehow. I have AoE working 
properly from my disk node to my desktop workstation so I know the 
technology works and that I have the server set up properly.

The server that cannot discover AoE devices is using a Tyan S2882-D 
Thunder K8SD Pro motherboard. Anyone know what ethernet drivers I should 
be using with this? It is very strange. It has two gigabit network 
ports. I understand it has a Broadcom gigabit chipset. But apparently it 
also has an Intel eepro10/100 chipset...maybe on only one of the ports. 
It is not clear. I cannot find any docs anywhere that explain this 
clearly. I originally booted it with the eepro10/100 chipset and that 
detected a network interface, but only one. And it did not seem to be 
able to do AoE discovery over that interface for whatever reason. I 
removed the intel driver and compiled the Broadcom NetXtreme II driver 
into the kernel and it did not detect any ethernet devices at all.

Is anyone using one of these boards? Care to tell me what driver you are 
using or exactly what kind of ethernet chipset it really has?
