Hi, While trying to understand how wmi work (in fact, it's very easy :) ), I wrote a small utility to dump _WDG. It's really usefull to see what GUID are present in a dsdt when you don't have the hardware and to find the object_id associated with this GUID. You can grab it here: http://xf.iksaif.net/dev/wmidump.html I mostly stole some code from wmi.c and added some printf :). -- Corentin Chary http://xf.iksaif.net -- 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
