Problems solved by technology
[0003] However, the aforementioned firmware may need to be updated after the server leaves the factory, and the baseboard management controller cannot monitor other units of the server at the same time during the firmware update process. That is to say, the baseboard management controller must pause when updating the firmware Monitoring operations, and the firmware update operation is quite time-consuming, the baseboard management controller cannot monitor other components for a long period of time, which may cause damage to the server during the firmware update process

Embodiment Construction
[0023] See Figure 1 Flowchart of an embodiment of a firmware renewal method according to the present invention. See Figure 2 Circuit diagram of a server having bi-firmware storage space according to the present invention. See Figure 3 for Figure 2 Circuit 13 of the selection operates on the circuit diagram of an embodiment of the first mode. See Figure 4 for Figure 2 Circuit diagram of an embodiment of the selected circuit 13 operating in the second mode. Please merge the references Figures 1 through 4 The server comprises a baseboard management controller 10, a first storage circuit 11, a second storage circuit 12 and a selection circuit 13. Two storage circuits 11, 12 may be flash memory (flash). Substrate management controller 10 comprises a control module 101 and an update module 102. Select circuit 13 is coupled between the substrate management controller 10 and the first storage circuit 11, and coupled between the substrate management controller 10 and the second storage cir...

The present invention provides a server with dual firmware storage space and its firmware update method. The method includes: the control module of the baseboard management controller obtains the firmware through the selection circuit when the selection circuit electrically connects the control module to the first storage circuit. The first firmware program is stored in the first storage circuit and executes the first firmware program; when the update module of the baseboard management controller is electrically connected to the update module with the second storage circuit by the selection circuit, the second storage circuit is updated according to the firmware update command through the selection circuit. The second firmware program is stored in the second storage circuit; the baseboard management controller is reset after the second firmware program is stored in the second storage circuit; and after the reset, the control module is electrically connected to the second storage circuit through the selection circuit, To obtain the second firmware program stored in the second storage circuit, and execute the second firmware program.
Description
【Technical field】 [0001] The present invention is about a server having a pluto-firmware storage space and a firmware update method thereof. 【Background】 [0002] Most servers contain a Baseboard Management Controller (BMC) that executes firmware to monitor and control all hardware units in the server. For example, the server contains a fan unit, the substrate management controller can monitor the system temperature, and control the speed of the fan according to the system temperature, when the temperature is higher, the substrate management controller controls the fan has a higher speed, when the temperature is lower, the substrate management controller controls the fan has a lower speed. The baseboard management controller plays a pivotal role in the server. [0003] However, the aforementioned firmware may have the need to update after the server leaves the factory, the substrate management controller in the process of firmware update can not monitor other units of the server ...
