Use
This is an internal call for OS use only and should not be used by user software.
The kernel calls this entry point in order to determine the list of modules that are required for the boot-time keyboard scan to be performed. This list does not need to include the any of the modules that are protected from being unplugged by the kernel (i.e. those before “FirstUnpluggableModule”) “FirstUnpluggableModule”).
Returning a value of -1 opts out of the boot-time keyboard scan. This is ill advised as it leaves no means to recover from a bad CMOS setup.
