Embodiment Construction

[0028] According to an embodiment of the present invention, a BIOS control method is provided.

[0029] Such as figure 2 As shown, the control method of the BIOS according to the embodiment of the present invention includes:

[0030] In step S201, the Base Board Management Controller (BMC for short) determines the control mode that needs to control the BIOS according to the input control command, wherein the control command is used to control the BIOS;

[0031] In step S203, the baseboard management controller controls the BIOS through the bridge of the motherboard to implement the function corresponding to the determined control mode.

[0032] Such as image 3 As shown, the baseboard management controller may be connected to multiple function ports on the bridge chip (for example, may be the south bridge), where each function port is used to trigger the BIOS to implement a corresponding function. For example, in image 3 It shows that the connected functional ports can i...

Abstract

The invention discloses a control method and a control device for a BIOS (basic input/output system). The method includes the steps: determining required control modes for controlling the BIOS by a base board management controller according to inputted control instructions, wherein the control instructions are used for controlling the BIOS; and controlling the BIOS by the base board management controller through a platform controller hub of a main board so as to realize functions corresponding to the determined control modes. The platform controller hub is controlled by the base board management controller, so that BIOS is controlled to realize the corresponding functions, a hardware jumper can be connected without opening a case, the BIOS can be conveniently controlled by means of various modes, a BIOS control process is simplified, and time and workload for operations such as maintenance, refreshing and the like on the BIOS are reduced.

Description

technical field [0001] The present invention relates to the field of computers, and in particular, to a control method and device for a Basic Input / Output System (BIOS for short). Background technique [0002] Such as figure 1 As shown, the bridge chip (PCH) on the motherboard of the computer such as server etc. is connected with BIOS, bridge chip PCH has multiple function ports, figure 1 The following function ports are shown in , Clear RTC (Real Time Clock), Descripter Mode, and Top Block Swap, and these ports are used to control the BIOS. For example, for Descripter Mode, a high level (High) means that triggering into Descripter Mode is prohibited. [0003] At present, when upgrading and maintaining the BIOS, Clear RTC (reset BIOS settings), Descripter Mode, and Top Block Swap are mainly used. For example, the system can be reset, some BIOS files can be upgraded, all BIOS files can be upgraded, and when the BIOS boot file is damaged, boot from the BIOS backup boot file...
