NAME
     acpi_rapidstart -- Intel rapid start technology ACPI driver

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

	   device acpi_rapidstart

     Alternatively, to load the driver as a module at boot time, place the following line in loader.conf(5):

	   acpi_rapidstart_load="YES"

DESCRIPTION
     The acpi_rapidstart driver provides support for Intel Rapid Start technology ACPI device interface.  Note that this is only for the ACPI
     device interface.	This has _CID PNP0C02 so it should be loaded at boot time to avoid attaching to the acpi_sysresource driver.

	     2		 Enter Fast Flash Standby in Critical Battery Wake enable

     dev.acpi_rapidstart.0.ftv
