Hello everyone (sespecially Jay!) I'm a little confused on the model/firmware: I just bought a DAC960PU-3 (D040397) thinking that I could replace the non-ultra PD that I have without problems. But the card just arrived, and it has two bios chips - 3.51 firmware version. While I am confident I could put root on it, will I be able to actually boot to an array on this card (as I do with my currnt setup) with the 3.5 firmware as opposed to the DEC 2.7 firmware? My system is an AS1200. Thank's Mike
BTW, if i can't use this dual chip setup, can the chips be repolaced with a single chip with the 2.7 firmware?
