In the embodiment of the present invention, control interface on the first control chip is connected by control circuit with the management interface of writing with a brush dipped in Chinese ink on the second control chip, by register configuration instruction, make the first control chip send control signal at control interface, the incoming level of writing with a brush dipped in Chinese ink management interface to the second control chip is controlled, so that the second control chip is write with a brush dipped in Chinese ink status information setting to instruction set firmware, thereby, can realize the setting of instruction set firmware being write with a brush dipped in Chinese ink to status information by the mode of instruction or software, improve the convenience of setting up procedure.
Embodiment bis-
The embodiment of the present invention provides a kind of instruction set firmware to write with a brush dipped in Chinese ink the method to set up of status information, and in the method, the control interface on the first control chip is connected by control circuit with the management interface of writing with a brush dipped in Chinese ink on the second control chip.
Wherein, the first control chip and the second control chip can be the control chips on computer motherboard, the second control chip is the control chip of having stored instruction set firmware and write with a brush dipped in Chinese ink status information, for example, when corresponding instruction set firmware is ME firmware (it is that ME firmware is write with a brush dipped in Chinese ink status information that instruction set firmware is write with a brush dipped in Chinese ink status information), the second control chip can be PCH chip so, writes with a brush dipped in Chinese ink accordingly the HDA_SDO interface that management interface can be PCH chip.The first control chip and the second control chip can be same control chips, can be also different control chips.Control interface is can be by the configuration of register data in control chip being changed to the interface of output level, for example GPIO (General Purpose Input Output, universal input output) interface, on control chip, can there be multiple control interfaces, each control interface can be to there being multiple registers, by the configuration to register data corresponding to control interface, can control the output of this control interface, for example export high level or output low level.The control chip that is provided with control interface can be served as the first control chip in the embodiment of the present invention, for example SIO (Super Input andOutput, super input and output) chip, EC (Embeded Controller, embedded controller) chip etc.
Control circuit can be the peripheral circuit of the control chip that arranges on mainboard, and the circuit structure of control circuit can have diversified design, in content below, can be elaborated to the structure of control circuit.
Below in conjunction with concrete embodiment, the treatment scheme shown in Fig. 1 is described in detail, particular content is as follows.
What preferably, the first control chip received is the register configuration instruction that BIOS (Basic Input Output System, Basic Input or Output System (BIOS)) sends.The setting options that in the display interface of BIOS, instruction set firmware can be set and write with a brush dipped in Chinese ink status information, described setting options comprise opening and closing.For example, these setting options can be shown as the prompt text of " open command collection firmware is write with a brush dipped in Chinese ink " and the option of " unlatching ", " closing " in display interface, if when technician selects the option of unlatching, instruction set firmware is set and writes with a brush dipped in Chinese ink status information for opening, if when the option that selection is closed, be set to close.Then, when described BIOS receive to these setting options instruction is set time, generate and send register configuration instruction.In BIOS, should record the register identification of the register that above-mentioned control interface is corresponding, and record " unlatching ", deploy content (this corresponding relation can specifically arrange according to the design of control circuit) that " closing " option is corresponding, in the time generating register configuration instruction, BIOS can add corresponding register identification and deploy content like this.
In addition, after guaranteeing that computing machine dispatches from the factory, user can not at will write with a brush dipped in Chinese ink instruction set firmware, can adopt following method: the factory state information of BIOS detection computations machine; If factory state information for not dispatching from the factory, shows above-mentioned instruction set firmware and writes with a brush dipped in Chinese ink the setting options of status information in the display interface of BIOS; If factory state information is for dispatching from the factory, in the display interface of BIOS, hide above-mentioned instruction set firmware and write with a brush dipped in Chinese ink the setting options of status information.
Factory state information can be stored in certain ROM on mainboard, in the time that computer starting is carried out BIOS, BIOS can read the factory state information in this ROM, and determine follow-up interface display according to the result reading, determine the setting options whether hiding instruction set firmware is write with a brush dipped in Chinese ink status information.
Concrete, the first control chip can, according to the data after configuration in this register, send control signal by above-mentioned control interface to control circuit, controls the incoming level of writing with a brush dipped in Chinese ink management interface of this control circuit to the second control chip.
The data that configure in register can determine the duty of corresponding control interface, preferably, in the time that open command collection firmware is write with a brush dipped in Chinese ink, the data of this register being configured in above-mentioned steps, make the duty of corresponding control interface in output high level, the high level of output is the control signal of sending.
