.Dd $Mdocdate: July 22 2010 $ .Dt PCKBC 4 .Os .Sh NAME .Nm pckbc .Nd PC (ISA) keyboard controller driver .Sh SYNOPSIS .Cd "pckbc* at isa? flags 0x00 " Pq "alpha, amd64, i386, loongson" .Cd "pckbc* at ebus? " Pq "sparc64" .Cd "pckbd* at pckbc?" .Cd "pms* at pckbc?" .Sh DESCRIPTION The .Nm driver handles resource allocation and device attachment for the traditional PC/AT keyboard controller. It provides two logical connections for child devices, the .Dq keyboard slot for a keyboard and the .Dq auxiliary slot for mice (the latter might be missing in older keyboard controllers). .Pp
The optional
.Dq slot
locator argument can be used to force unusual connections of devices to
logical slots.
This feature is for experimentation only, it will not be
useful in normal operation.

p To avoid attaching a phantom PS/2 keyboard device, the .Nm driver will attempt to detect USB legacy keyboard emulation on amd64 and i386 systems. Unfortunately, the detection heuristics may fail on older systems with a real PS/2 keyboard. The keyboard can be forced to attach on these systems, by changing the device flags to 1. .Sh SEE ALSO .Xr ebus 4 , .Xr intro 4 , .Xr isa 4 , .Xr pckbd 4 , .Xr pms 4 , .Xr boot_config 8
