Well, its partly based on your pathces, I just took out the X

I still has some update problems, but given a couble of hours
those can probably be ironed out.

Yes, I now that, but it would also give some "interesting" possibilities

to the card, and to pass chuncks of data when it runs.

I'll work on it over the next couble of days...
