    Hi Jeremy!

    Infos look OK to me, as you have
    WISHBONE Slave interface's control signals
    tied off to zero, so PCI Master won't ever do any
    accesses and PCI Target never drives FRAME or
    IRDY.

    I'm puzzled why this doesn't work for you!
    I have only one idea left (it's a long shot though :)):
    Can it be, that device isn't shown at boot-up because
    BIOS doesn't recognize the vendor ID? Can you change
    it to the Altera's core one and try that?
    The only other course of action I can recommend from
    here on is simulation - just read vendor/device ID and
    configure BAR's. Then if this works, work through
    gate level and timing simulations - if it's not board
    problem, the thing should break at some point.

    Is there anyone on the list using the core in Altera to
    help us out? I know that at least a few people have used the core
    succesfully on Altera.

    Best regards,
    Miha Dolenc
