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.
