    Yes - I've started with extracting the PDA information in a way so that it
    can be read by the likes of prism2dl. I find that I now need to decode the
    hex files in much more detail (Up to know I assumed it was just an intel
    hex file which needed to be uploaded in a some bit of ram. Turns out there
    is more to it than that :-(.

    Aye - I've also added an ioctl to get the 3 id/major/minor/variant values
    for nic/pri/sec; which is enough to drive prism2dl together with the PDA
    info.

    Thanks - will limit myself to that.
