 Triggering Firmware Update 
 *****************************

+|SPN| supports triggering firmware update from Linux, Windows, and |SPN| shell.
 
 |SPN| provides a platform independent abstracted way of triggering firmware update from operating system. |SPN| provides two ACPI methods, \DWMI.WQ00 for read and \DWMI.WS00 for write to a platform specific chipset register that can survive a reset to signal firmware update. Please refer to **Triggering Firmware Update** section of desired board page in **Supported Hardware** to find Sample implementation.
