SYNOPSIS

To compile this driver into the kernel, place the following line in your kernel configuration file:

device acpi_wmi

Alternatively, to load the driver as a module at boot time, place the following line in loader.conf5:

acpi_wmi_load="YES"

DESCRIPTION

The driver provides an interface for vendor specific WMI implementations (e.g. HP and Acer laptops). It creates /dev/wmistat%d, which can be read to get information about GUIDs found in the system.
