I'm not sure of the criteria, but this is what I'm running: atapci0: <SiI 3124 SATA300 controller> port 0xdc00-0xdc0f mem 0xfbeffc00-0xfbeffc7f,0xfbef0000-0xfbef7fff irq 17 at device 4.0 on pci7 atapci1: <SiI 3124 SATA300 controller> port 0xac00-0xac0f mem 0xfbbffc00-0xfbbffc7f,0xfbbf0000-0xfbbf7fff irq 19 at device 4.0 on pci3 I added ahci_load="YES" to loader.conf and rebooted. Now I see: ahci0: <ATI IXP700 AHCI SATA controller> port 0x8000-0x8007,0x7000-0x7003,0x6000-0x6007,0x5000-0x5003,0x4000-0x400f mem 0xfb3fe400-0xfb3fe7ff irq 22 at device 17.0 on pci0 Which is the onboard SATA from what I can tell, not the controllers I installed to handle the ZFS array. The onboard SATA runs a gmirror array which handles /, /tmp, /usr, and /var (i.e. the OS). ZFS runs only on on my /storage mount point. -- Dan Langille - http://langille.org/
