.Dd May 17, 2001 .Dt ATACONTROL 8 .Os FreeBSD .Sh NAME .Nm atacontrol .Nd ATA device driver control program .Sh SYNOPSIS .Nm .Aq Ar command .Ar channel Op Ar args

p .Nm c attach .Ar channel .Nm c detach .Ar channel .Nm c reinit .Ar channel .Nm c mode .Ar channel .Op Ar mastermode slavemode .Nm c info .Ar channel .Nm c list .Sh DESCRIPTION .Nm is a control program that provides the user access and control to the .Fx .Xr ata 4 subsystem.

p .Nm can cause severe system crashes and loss of data if used improperly, please exercise caution when using this command!

p .Nm supports the following commands: l -tag -width "attach" t Ic attach Attach an ATA .Ar channel , devices on the channel are probed and attached as is done on boot. t 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. t 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. t 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. t Ic info Show info about the attached devices on the .Ar channel , currently only the device name and manufacture/version strings are shown. t Ic list Show info about all attached devices on all active controllers. .El .Sh SEE ALSO .Xr ata 4 .Sh HISTORY The .Nm utility first appeared in .Fx 5.0 . .Sh AUTHORS .An -nosplit The .Nm utility was written by .An S\(/oren Schmidt .Aq sos@FreeBSD.org .
