    I just noticed that I forgot a NOT is my reply to this posting that made
    me say the opposite I wanted to say (at least a NOT has to be added as
    follow):

    : Your hardware is probably quite fine. Just never try to read more than the
    : first 64 bytes of PCI configuration space from any device, since the
    : remaining bytes are device specific and the PCI specifications does
    DO NOT
    : explicitely required this space to be readable without side effects.
    REQUIRE

    Martin, I am expecting you to let us know how I am wrong. ;-)


    Regards,
    Gerard.
