.Dd December 8, 2000 .Dt ATACONTROL 8 .Os FreeBSD .Sh NAME .Nm atacontrol .Nd ATA device driver control program .Sh SYNOPSIS .Nm .Aq Ar command .Op channel [args] .Nm c attach .Op channel .Nm c detach .Op channel .Nm c reinit .Op channel .Nm c mode .Op channel .Op mastermode slavemode .Nm c info .Op channel .Sh DESCRIPTION .Nm is a control program that provides the user access and control to the .Fx ATA 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:

p l -tag -width 8n t Ic attach Attach an ATA channel, devices on the channel are probed and attached as is done on boot.

p t 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.

p t 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.

p 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 PIO3, udma2, udma100, case does not matter.

p t Ic info Show info on the device on the channel, currently only the device name and manufacture/version strings are shown.

p .Sh HISTORY The .Nm driver first appeared in .Fx 5.0 . .Sh AUTHORS .An -nosplit The .Nm driver was written by .An S\(/oren Schmidt .Aq sos@FreeBSD.org .
