As a general rule, you want the 3.x or later firmware, although what testing I've done with the later 2.x revisions hasn't shown anything really bad up. The 4.x firmware also adds the stand-alone array management tools, which are nice to have. One advantage you have with the FreeBSD driver is that we support the 2.x firmware (one flash chip, rather than two), wheras the Linux folks don't. Performance on these low-end adapters is fairly similar between the 2.x and 3.x firmware, so you can sometimes score a real bargain if you're just looking for something to play with. (The 2.x firmware has had a long life largely because it's what Compaq are still using in some of their Alpha systems. I recommend 2.70 at the moment, but a flash upgrade is fairly easy.) -- \\ 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
