+ *
+ * ACPICA policy for new _OSI strings:
+ *
+ * It is the stated policy of ACPICA that new _OSI strings will be integrated
+ * into this module as soon as possible after they are defined. It is strongly
+ * recommended that all ACPICA hosts mirror this policy and integrate any
+ * changes to this module as soon as possible. There are several historical
+ * reasons behind this policy:
+ *
+ * 1) New BIOSs tend to test only the case where the host responds TRUE to
+ * the latest version of Windows, which would respond to the latest/newest
+ * _OSI string. Not responding TRUE to the latest version of Windows will
+ * risk executing untested code paths throughout the DSDT and SSDTs.
+ *
+ * 2) If a new _OSI string is recognized only after a significant delay, this
+ * has the potential to cause problems on existing working machines because
+ * of the possibility that a new and different path through the ASL code
+ * will be executed.
+ *
+ * 3) New _OSI strings are tending to come out about once per year. A delay
+ * in recognizing a new string for a significant amount of time risks the
+ * release of another string which only compounds the initial problem.
+ *
+ *****************************************************************************/
+/*
+ * Strings supported by the _OSI predefined control method (which is
+ * implemented internally within this module.)
+ *
+ * March 2009: Removed "Linux" as this host no longer wants to respond true
+ * for this string. Basically, the only safe OS strings are windows-related
+ * and in many or most cases represent the only test path within the
+ * BIOS-provided ASL code.
+ *
+ * The last element of each entry is used to track the newest version of
+ * Windows that the BIOS has requested.
