Idid it! after 3 days of diging acpi specifications , till i found http://www.microsoft.com/whdc/system/pnppwr/wmi/wmi-acpi.mspx I'm so happy becouse this is my first at all kernel module/driver in my life i have ever written. very hot uncleaned code atached bellow. Short abstract, tomorrow I will write more, There is no ACPI , there is Microsoft invention combo of ACPI+WMI+MOF so we call acpi method which calls wmi method with code located in bios or embbeded as MOF data into acpi ...
