8.1 ATA_CAM system

I'm slightly confused by the man pages for the new ATA_CAM kernel option. Does this provide the same function as the AHCI module in 8.0? Do I need to have both of them enabled/loaded now?
 
No. AHCI is specifically for AHCI (and compatible) controllers. It will present a cam (SCSI) interface to the system to access drives.
The ATA_CAM option adds the cam interface to the traditional ATA (IDE) controllers.
They provide similar functionality (make drives accessible via cam) but they are not the same.


If I understood correctly they're moving everything over to cam, so no more ata devices. At least from the system's point of view.
 
Ah ok, so both options are necessary if you want to cover SATA and IDE based devices.
Thanks for the clarification!
