I'm sorry, I don't recall seeing this question the first time around; the short answer is that the 1600 will be supported shortly after someone gives/lends me one to do the work. I have the necessary information, just no controller to test with. > As an aside, anyone know what memory is compatible with the 1400 > controllers.

(I never have known the difference between > memory advertised as ECC and parity :) With byte-wide memory, you need two extra bits for ECC rather than just one for parity. 72-pin SIMMs are actually 32 bits wide; some controllers are happy with parity memory (36 bits), others want byte-ECC memory (eg. Mylex AcceleRAID) which is 40 bits wide and incredibly expensive. I *think* the 1400 will be happy with just plain parity memory. If in doubt, buy from a supplier with an exchange plan. -- \\ 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
