Hi Tom,

I think that part of the EDK IPIF interface is broken, at least in EDK 
3.1/3.2

There seems to be DMA support coded into the driver, but comments around 
it suggest that IPIF issues prevent it from working properly.

I'm not sure about EDK6.1, maybe it's been fixed, and the driver code 
can just be enabled.

Regards,

John
