Putting the root partition onto a mirrored disk is always a good idea if the hardware supports it. In this case, the DPT controller does. It presents a virtual disk(s) to the BIOS for booting. Entry level DPT is a paradox. Not too many of their low end cards are still being made. You'll probably have to use a SmartRAID IV at minimum. > Thanks, > -Pat Tom To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-isp" in the body of the message
