Embodiment
According to embodiments of the invention, the method for refreshing of a kind of BIOS is provided.
As shown in Figure 1, comprise according to the method for refreshing of the BIOS of the embodiment of the invention:
Step S101, under the situation that need refresh the BIOS of computing machine, the CPU that baseboard management controller (BMC) stops computing machine conducting interviews to the storer of BIOS;
Step S103, baseboard management controller conducts interviews to storer, and BIOS is refreshed.
Wherein, receive at baseboard management controller under the situation of BIOS refresh requests, confirm and to refresh BIOS; And when BIOS was refreshed, baseboard management controller can refresh the BIOS in the storer according to refresh requests.At this moment, in refresh requests, can carry the correlation parameter of refresh operation, the information such as content that BIOS upgrades.
After BIOS was refreshed, baseboard management controller recovered the visit of CPU to storer.
In addition, in scheme of the present invention, CPU is connected with the bridge sheet of computer motherboard, and the bridge sheet is connected with baseboard management controller, and baseboard management controller is connected with storer; Alternatively, baseboard management controller is connected with the bridge sheet with storer through Serial Peripheral Interface (SPI) (SPI); In addition, CPU is connected with the bridge sheet through direct media interface (DMI); And above-mentioned bridge sheet can be south bridge.
To the instantiation of embodiment of the present invention be described with reference to Fig. 2 below.As shown in Figure 2; In order to realize technical scheme of the present invention; Can the storer FLASH of BIOS be received on the SPI of BMC; BMC is connected through another SPI and south bridge (being PCH shown in the figure), and CPU (CPU0) is passed through DMI and is connected with PCH, and BMC can and refresh the BIOS among the FLASH through the SPI interface accessing between itself and the storer FLASH.
When the BIOS operate as normal, FLAH is operated by CPU; When BIOS need refresh, FLASH is operated refreshing of realization BIOS by BMC.BMC has network function, can BMC be operated FLASH, thereby realize remote reflash BIOS through network remote control BMC.
