    In this thread there is a the pic of the DV2000 systemboard showing a second mPCIe slot, which if is port2 could potentially mean it could be ganged with the expresscard slot to get a x2 1.0 link.

    [​IMG] [​IMG] L: the unknown mPCIe slot. I only have the pins.
    R: DV2000 port layout. HD4670 attached with PE4L-EC2C.

    Everest output on the tested DV2000 with a HD4670 connected to
    the expressport via a PE4L shows:
    • expresscard slot = port1
    • wifi mPCIe slot = port4
    The DV2000 I'm using for testing does not have a socket there, just the solderable pins.

    Can anyone with a socketted DV2000 plug their wifi card into that slot, capture the Everest Southbridge output to identify what port number that slot corresponds to?

    Why the interest in port numbers?

    With the DIY ViDock project, I have successfully got a HD4670 working on a DV2000 in x1 1.0 link speed. That loses ~50% of x16 2.0 performance. If those mPCIe pins is port2, then perhaps a HD5870 in x2 1.0 link speed upgrade is possible. HD5870 PCI-E scaling shows it gets a 3dmark06 value of over 20k in a x1 2.0 link (same as x2 1.0). Quite an upgrade to the onboard GMA950 graphics.
