I tried it with > the Jan 18th SNAP but the nca driver didn't detect it. well.. that ncr chip does work (at least with a 960323 or 960801 snap)... I've had an old 8bit card with it on it.... the card I have has a block of 8... it probably doesn't have a bios rom on it... but you might try 0x[23][45]0 for the iobase... also... irqs 3, 5, or 7... > Anybody know what the switch settings do and whether or not this > thing can be made to play nice with FreeBSD? I realize it's practically > junk, but then so is most of my equipment. :) it is really quite bad... on my old machine... if I did any type of transfer off a 2x cdrom.. the cpu would hit max usage due to the polled io nature of the card... but it does work for cdroms :)... hope you get it working.. ttyl..
