+.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 acpi? flags 0x00          " Pq "amd64"
+.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, or emulations thereof.
+It provides up to 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,
+or recent emulations).
+.Pp
+To avoid attaching a phantom PS/2 keyboard device, the
+.Xr isa 4
+attachment of 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.
+.Pp
+The
+.Xr acpi 4
+attachment of the
+.Nm
+driver defaults to attach only where it would perform better than its legacy
+.Xr isa 4
+attachment.
+Should this logic be insufficient, it is possible to force it to always attach,
+by changing its device flags to 1.
