Yes, and it won't work without some changes. Right now you'll need to move to -current to get those changes, but there is a slight chance that they will be brought into 3.x at some point. In any case, you'll need to restrict the maximum amount of memory (MAXMEM) to 4GB-64MB (it works out to the number 4128768) in order to for the system to not smash into the PCI space during the memory probe. >2) We're also planning to buy a second SC450NX.

It still doesn't work, so yes, you'll need an Adaptec. -DG David Greenman Co-founder/Principal Architect, The FreeBSD Project - http://www.freebsd.org Creator of high-performance Internet servers - http://www.terasolutions.com To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hardware" in the body of the message
