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.

History

       The acpi_rapidstart driver first appeared in FreeBSD 10.0.
