I don't know. I'm waiting for someone to actually write documentation on this. I keep seeing commits talking about ATA disks via CAM (e.g. SCSI emulation for ATA disks), but the only thing I'm aware of that exists is SCSI emulation for ATAPI devices. > I've just tried "Modular ATA" configuration of Intel ICH7-based system plus "device ahci" > minus all traditional ata(4) kernel configuration, the kernel builds fine > but boot messages do not show any attempt to detect my SATA HDD, > so root mount just fails (I use GEOM UFS labels in my /etc/fstab). > Typing ? at "mounroot" prompt I see only daX devices standing for my USB cardreader > and no device for HDD. This sounds like a different problem. You may want to talk to mav@ about this. > It seems I miss ada(4) device and I cannot find it in 8.0 - not ada.ko nor "device ada".
