|
supports the following commands:

|
.It Ic attach
|
|
Attach an ATA channel, devices on the channel are probed and attached as
|
|
is done on boot.
|
|
.Pp
|
|
.It Ic detach
|
|
Detach an ATA channel, devices on the channel are removed from the kernel,

|
and all outstanding tranfers etc are returned back to the system marked
|
|
as failed.
|
|
.Pp
|
|
.It Ic reinit
|
|
Reinitialize an ATA channel. Both devices on the channel are reset and
|
|
initialized to the parameters the ATA driver has stored internally.
|
|
Devices that has gone bad and no longer responds to the probe, or devices
|
|
that has physically been removed are removed from the kernel. Likewise
|
|
are devices that show up during a reset, probed and attached.
|
|
.Pp
|
|
.It Ic mode
|
|
Without the two mode arguments the current transfer modes of both
|
|
devices are printed. If the mode arguments are given, the ATA driver
|
|
is asked to change the transfer modes to those given. The ATA driver
|
|
will reject modes that is not supported by the hardware.
|
|
Modes are given like PIO3, udma2, udma100, case does not matter.
|
|
.Pp
