If you enable "options ATA_CAM" in the kernel, which uses the old ata(4) driver via some cam(4) shims, then you also get the adaX device nodes. There's currently 4 ways to access PATA/SATA disks: - old-style ata(4) using adX device nodes - old-style ata(4) using ataahci(4) for ACHI-like access to PATA/SATA disks, I believe using adX - old-style ata(4) via ATA_CAM using adaX device nodes - new-style ahci(4)/siis(4)/another(4) using adaX device nodes I forget the name of the other AHCI-style driver. The first two options uses atacontrol to manage the disks. The last two options use camcontrol to manage the disks. I believe the plan in 9.0 is to have everything accessed via ATA_CAM/ahci(4) so all PATA/SATA drives show up the same, as adaX, with everything being managed via camcontrol, finally unifying all PATA/SATA/SCSI/SAS disk access via cam(4). -- Freddie Cash fjwc...@gmail.com _______________________________________________ freebsd-current@freebsd.org mailing list http://lists.freebsd.org/mailman/listinfo/freebsd-current To unsubscribe, send any mail to "freebsd-current-unsubscr...@freebsd.org"
