Abstract:
1. A key processing method for use in a computer system having at least one BIOS (basic input output system) and one controller, comprising: determining, by the BIOS, after a predetermined time period repeatedly, whether a specific hotkey has been pressed, wherein the predetermined time period is generated by a clock signal line of a South-Bridge chip or the controller; if it is determined that a specific hotkey has been pressed, the BIOS acquires an identification data of the specific hotkey from the controller and performs a service corresponding to the identification data of the specific hotkey; and shortening the length of the predetermined time period during a next counting cycle after determining that the hotkey is the specific hotkey in order to precisely determine what key has been pressed, wherein the shortened time period will be kept for a predetermined time period.
