When developing and maintaining the functions of the BMC, you need to update the firmware of the BMC (Firmware, FW). The conventional BMC blade update tool requires a software program running on the BMC to update the BMC firmware. When the software program running on the BMC dies or is damaged, there is no way to perform the firmware update of the BMC. In addition, the software program running on the BMC occupies part of the resources of the BMC processor, resulting in a slower firmware update of the BMC.

When the baseboard management controller 13 is running on the server 1, the busbar controller of the server 1 (such as the PCI busbar controller, not shown in FIG. i) configures a small storage for the baseboard management controller 13. A space (such as a 256-bit space) is used to buffer the configuration information of the baseboard management controller 13. In this embodiment, the acquisition module 101 can read the configuration information of the substrate management controller 13 from the busbar control system through the operating system of the server 1. [0012] 0 Step S02 'The acquisition module 1〇1 is found as the address of the baseboard management controller 13 on the PCI bus/PCIE bus and is transmitted through the PCI convergence according to the acquired configuration information.

[0013] Step S03, the mapping module 1〇2 maps the firmware storage space to the memory space of the processor 11 according to the configuration information of the firmware storage space. A virtual firmware storage space is allocated to the substrate management controller 13 in the memory space. [0014] Step S04' The execution module 1〇3 writes the new firmware information of the base management controller 13 to the virtual firmware storage to be further 099140258 form number A0101 page 7/14 page 0992070138-0 201222413 In the space, the firmware of the substrate management controller 13 is updated. The to-be-updated firmware data is pre-stored in the memory 12. [0015] In the embodiment, the firmware storage space for storing the firmware data in the memory space of the substrate management controller 13 is mapped into the memory space of the processor 11 by using a virtual memory technology. Therefore, a virtual firmware storage space of the substrate management controller 13 is virtualized in the memory space of the processor 11, so that the execution module 103 can directly operate the virtual firmware storage space to access the substrate management control. The firmware of the device 13 stores space without being accessed through I/O (input/output). By implementing the present invention, the firmware of the substrate management controller 13 can be updated faster and with better independence. [0016] It should be noted that the above embodiments are merely illustrative of the technical solutions of the present invention and are not intended to be limiting, and the present invention will be described in detail with reference to the preferred embodiments. The technical solutions are modified or equivalently substituted without departing from the spirit and scope of the technical solutions of the present invention.
