IB card detection on PLX switch.

Sir,

I am testing two IB card (MCB193A-FCAT) in our server.

The server can detect the IB card through the PEX8764 PCIe switch IC.

The two card has different IC revision, A5 and B3.

In A5, the card detect only x1 link, but, in B3, detect well x16.

So , I want to know who know the difference of two IC revision.

Thanks

Hong
