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.

SYSCTLS

     The following sysctl(8) nodes are currently implemented:

     dev.acpi_rapidstart.0.ffs
	     Rapid start flag.	It is a bitwise OR of the following:

	     1		 Enter Fast Flash Standby in RTC wake.
	     2		 Enter Fast Flash Standby in Critical Battery Wake enable

     dev.acpi_rapidstart.0.ftv
	     Fast Flash Standby timer value in minutes.
