By the way, is there a reason why I can't find my ticket by its number? http://www2.lm-sensors.nu/~lm78/support2.html?search=1941&sort=index leads to an error page with "Sorry, nothing found. Try searching for something less specific, or 'list all'" ... I just understood the syntax of /proc/ioports and I see that the 02f8-02ff range is taken by the serial driver or something. This kind of makes sense after looking at the mobo block diagram from gigabyte: page 7 of: http://america.giga-byte.com/MotherBoard/FileList/Manual/manual_k8nxpsli_e.pdf My IT8712F chip controls the COM port. o_O Thanks.
