30.Sh NAME
31.Nm acpi_wmi
32.Nd "ACPI to WMI mapping driver"
33.Sh SYNOPSIS
34To compile this driver into the kernel,
35place the following line in your
36kernel configuration file:
37.Bd -ragged -offset indent
38.Cd "device acpi_wmi"
39.Ed
40.Pp
41Alternatively, to load the driver as a
42module at boot time, place the following line in
43.Xr loader.conf 5 :
44.Bd -literal -offset indent
45acpi_wmi_load="YES"
46.Ed
47.Sh DESCRIPTION
48The
49.Nm
50driver provides an interface for vendor specific WMI implementations
51(e.g. HP and Acer laptops).
52It creates /dev/wmistat%d, which can be read to get
53information about GUIDs found in the system.
54.Sh FILES
55.Bl -tag -width /dev/wmistat%d -compact
