| 2 | Definition of the global NVS area protocol. This protocol\r | |
| 3 | publishes the address and format of a global ACPI NVS buffer\r | |
| 4 | used as a communications buffer between SMM code and ASL code.\r | |
| 5 | The format is derived from the ACPI reference code, version 0.95.\r | |
| 6 | Note: Data structures defined in this protocol are not naturally aligned.\r | |
