If you want to boot from the array you need to have the array config in a way that fits the controller, if thats not needed you can move around as you see fit, you can even make ATA RAID's on any ATA controller not just Promise or Highpoint as loong as you wont boot from it. I guess I should make an option to atacontrol that can convert between HPT/Promise format or maybe just silently write both to the disks ;) -Søren To Unsubscribe: send mail to majordomo@FreeBSD.org with "unsubscribe freebsd-hackers" in the body of the message
