supports the following commands:
|
|
.Bl -tag -width "attach"
|
|
.It Ic attach
|
|
Attach an ATA

|
.Ar channel ,
|
|
devices on the channel are probed and attached as
|
|
is done on boot.
|
|
.It Ic detach
|
|
Detach an ATA
|
|
.Ar channel ,
|
|
devices on the channel are removed from the kernel,
|
|
and all outstanding transfers etc. are returned back to the system marked
|
|
as failed.
|
|
.It Ic reinit
|
|
Reinitialize an ATA
|
|
.Ar 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.
|
|
.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
|
|
.Dq Li PIO3 ,
|
|
.Dq Li udma2 ,
|
|
.Dq Li udma100 ,
|
|
case does not matter.
|
|
If one of the devices mode should not be changed, use a nonexisting mode
|
|
as argument (i.e.\&
|
|
.Dq Li XXX ) ,
|
|
and the mode will remain unchanged.
|
