They should, although there are apparently some HP-specific oddities inside the firmware. If you use a non-HP setup utility, it should clear the "HP mode" bit, which will turn it into a standard controller. The AMI driver also supports the later HP NetRAID controllers. > When Linux first began supporting the DAC960s, the driver didn't support 2.x > firmware revisions.

Linux still doesn't, to the best of my knowledge, support the 2.x firmware. I spent quite a bit of time chasing the documentation due to the 2.x firmware's heavy use in Digital/Compaq systems. I'd strongly advise updating to 2.42 or later firmware (2.70 preferable). -- \\ Give a man a fish, and you feed him for a day. \\ Mike Smith \\ Tell him he should learn how to fish himself, \\ msmith@freebsd.org \\ and he'll hate you for a lifetime. \\ msmith@cdrom.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-stable" in the body of the message
