Embodiment Construction

[0011] In order to make the above and other objects, features and advantages of the present invention more comprehensible, preferred embodiments are listed below and described in detail with accompanying drawings.

[0012] The invention provides a method and device for updating firmware.

[0013] The method for updating firmware of the present invention can update the firmware of the keyboard control chip in an operating system in a multi-tasking environment, without causing the operating system to crash or the basic input and output system to be damaged.

[0014] FIG. 1 shows a schematic diagram of pin positions of the peripheral control chip and the storage medium of the present invention.

[0015] The peripheral control chip in the present invention refers to the South Bridge (South Bridge) control chip 101, which has pins such as EGPIO8, EGPIO9, ECSMI# and ECSCI#, and # indicates that the pin is started with a low potential (low) ( active). The storage medium 102 general...

Abstract

This invention provides a method for updating firmwares and a device, which interrupts the coherent connection between the firmware of the key board control wafer and the operation system, and a BIOS sends a system call to inform the firmware of the wafer to open its updata routine, then the BIOS sends a control order to release the antiwriting of the firmware of the order to release the antiwriting of the firmware of the wafer. Two specific pins of a peripheral device control wafer are set to be high potential to release the antiwriting of the BIOS then to updata the firmware to be restarted with the antiwriting of the BIOS to restart the operation system after finishing firmware updata.

Description

technical field [0001] The present invention relates to a method for updating firmware, and in particular relates to a method for updating firmware of a keyboard control chip (KBC, Keyboard Controller) used in a computer device Background technique [0002] At present, the keyboard control chip is mostly designed as a multi-function control chip. In addition to the original keyboard control function, it also integrates functions such as monitoring temperature, fan operation status, and screen brightness. As far as desktop computers are concerned, the firmware of the keyboard control chip is burned separately from the basic input and output system, and they are respectively burned in different storage media. , the firmware of the keyboard control chip is burned separately from the BIOS, and recently, in order to save costs, the two firmwares are burned in the same storage medium, that is, the firmware of the keyboard control chip is embedded in the BIOS. [0003] In the trad...
