+ * From pre-history through Linux-2.6.22, Linux responded TRUE upon a BIOS
+ * OSI(Linux) query.

+ * Unfortunately, reference BIOS writers got wind of this and put
+ * OSI(Linux) in their example code, quickly exposing this string as
+ * ill-conceived and opening the door to an un-bounded number of BIOS
+ * incompatibilities.
+ *
+ * For example, OSI(Linux) was used on resume to re-POST a video card on
+ * one system, because Linux at that time could not do a speedy restore in
+ * its native driver. But then upon gaining quick native restore
+ * capability, Linux has no way to tell the BIOS to skip the time-consuming
+ * POST -- putting Linux at a permanent performance disadvantage. On
+ * another system, the BIOS writer used OSI(Linux) to infer native OS
+ * support for IPMI! On other systems, OSI(Linux) simply got in the way of
+ * Linux claiming to be compatible with other operating systems, exposing
+ * BIOS issues such as skipped device initialization.
+ *
+ * So "Linux" turned out to be a really poor chose of OSI string, and from
+ * Linux-2.6.23 onward we respond FALSE.
+ *
+ * BIOS writers should NOT query _OSI(Linux) on future systems. Linux will
+ * complain on the console when it sees it, and return FALSE. To get Linux
+ * to return TRUE for your system will require a kernel source update to
+ * add a DMI entry, or boot with "acpi_osi=Linux"

- * The story of _OSI(Linux)
- *
- * From pre-history through Linux-2.6.22,
- * Linux responded TRUE upon a BIOS OSI(Linux) query.
- *
- * Unfortunately, reference BIOS writers got wind of this
- * and put OSI(Linux) in their example code, quickly exposing
- * this string as ill-conceived and opening the door to
- * an un-bounded number of BIOS incompatibilities.
- *
- * For example, OSI(Linux) was used on resume to re-POST a
- * video card on one system, because Linux at that time
- * could not do a speedy restore in its native driver.
- * But then upon gaining quick native restore capability,
- * Linux has no way to tell the BIOS to skip the time-consuming
- * POST -- putting Linux at a permanent performance disadvantage.
- * On another system, the BIOS writer used OSI(Linux)
- * to infer native OS support for IPMI! On other systems,
- * OSI(Linux) simply got in the way of Linux claiming to
- * be compatible with other operating systems, exposing
- * BIOS issues such as skipped device initialization.
- *
- * So "Linux" turned out to be a really poor chose of
- * OSI string, and from Linux-2.6.23 onward we respond FALSE.
- *
- * BIOS writers should NOT query _OSI(Linux) on future systems.
- * Linux will complain on the console when it sees it, and return FALSE.
- * To get Linux to return TRUE for your system will require
- * a kernel source update to add a DMI entry,
- * or boot with "acpi_osi=Linux"
