You're welcome ;)

Beware: the KZPSA-BB (I have one here) uses a 53C720 chip. And it is an
intelligent card, sporting an i960 cpu etc. Not your run of the mill
ncr card. Needs a special driver. And it is a long card, so check if
it will fit in your case (CPU heatsinks come to mind).

Mine is available for trade BTW. So if someone is interested drop me a line.

SRMs understand KZPSA-BB. I have a AS1000/4-400 at work that uses a
KZPSA to boot from a HSZ50 raid array.

Be careful.. does not apply to KZPSA e.g.

I have a noname Taiwan ncr810 board that works fine. My hacked Multia
riser cards (with 810 chip) also work fine in my NoName & Aspen Alpine
(see also: http://www.tcja.nl/~wilko/ncr_hack.html).
