Abstract

The invention discloses a control circuit, a connectivity controller, a connectivity control method and a main board, and belongs to the field of computers. The control circuit comprises the connectivity controller, a PCH, a BMC, a converter, a first storer and a second storer, wherein the first storer is used for storing an ME mirror image, and the second storer is used for storing a BIOS image. According to the control circuit, the ME mirror image and the BIOS image are stored in the first storer and the second storer respectively, and therefore in the process of upgrade of the BIOS, the BMC can upgrade the BIOS image stored in the second storer through a third SPI bus and a fourth SPI bus. The control circuit, the connectivity controller, the connectivity control method and the main board solve the problem that the SPI buses between the PCH and the SPI are disconnected in the process of upgrade of the BIOS, and achieve the purposes of guaranteeing normal operation of system services in the process of upgrade of the BIOS, and saving a large amount of software overhead.

Description

technical field [0001] The invention relates to the field of computers, in particular to a control circuit, a communication controller, a communication control method and a main board. Background technique [0002] ME (Management Engine, Management Engine) and BIOS (Basic Input Output System, Basic Input Output System) are a set of programs solidified on the motherboard of the computer. Among them, ME is responsible for the system startup control, power on and off control, power management and other tasks; BIOS provides the lowest and most direct hardware setting and control for the computer. During the operation of the computer, it is necessary to perform control operations such as reading or upgrading the ME and BIOS. [0003] Please refer to figure 1 , which shows the connection schematic diagram of ME and BIOS control circuit in the prior art, wherein, the control circuit includes PCH (Platform Controller Hub, platform control center), BMC (Baseboard Management Control...
