For example, if Microsoft released a follow-on operating system in 2003, it will probably be assigned a string of Windows 2003. This operating system would then return TRUE for the strings Windows 2001 and Windows 2003, and it would return FALSE for all other strings." So, no, it is not a test for Linux. Windows reports all versions, not just the current one. -- Matthew Garrett | mjg59@xxxxxxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-acpi" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
