Embodiment

[0022] In computer systems such as desktop computers and notebook computers, the Super I / O module includes different input and output controllers, which can separately control the PS / 2 port, serial port, and parallel port of the computer system. ports, game ports, etc. to communicate with the peripherals of the computer system. The aforementioned input and output controllers can be, for example, PS / 2 port controllers, serial port controllers, parallel port controllers, and game port controllers, wherein the PS / 2 port controllers can be used to control keyboards connected to PS / 2 and mouse, and the parallel port controller can be used to control the printer connected to the parallel port.

[0023] figure 1 It shows a computer system 100 according to an embodiment of the present invention. The computer system 100 includes an I / O port 110, a super I / O module (super I / O) 120, a serial peripheral interface (SPI) flash memory 130, a joint test working group (JTAG) circuit / bus 140 ...

Abstract

The embodiment of the invention discloses a super input-output module, a computer system and a control method thereof, which are used for controlling at least input-output port of the computer system. The super input-output module comprises a controller, a signal detector and a selector. The controller supports a function corresponding to the input-output port. The signal detector receives an input signal from the input-output port, detects whether the input signal has an identification code, and generates a selection signal according to the identification code when the signal detector detects the identification code. The selector receives the selection signal and selectively provides the input signal to one of the controller and a function circuit of the computer system according to the selection signal. According to the embodiment of the invention, a user can directly carry out operations such as control, debug and burn on elements inside the computer system.

Description

technical field [0001] The invention relates to a super input and output module of a computer system, in particular to a method for using the super input and output module to control components in the computer system. Background technique [0002] At present, the data for executing the boot process of some computer systems is stored in the serial peripheral interface (SPI) flash memory of the computer system. Therefore, when the data update in the flash memory fails, the maintenance engineer must first disassemble the main frame of the computer system, and desolder and remove the SPI flash memory on the mainboard. Then, the maintenance engineer will use the programmer to burn the desoldered SPI flash memory for data update. Then, the maintenance engineer will solder the programmed SPI flash memory back to the main board, and then install it back into the main case of the computer system. Therefore, traditionally, maintenance engineers need to perform the above cumbersome s...
