The memory 110 defines a shared memory 111 in which the shared space 111 stores specific data.

The processor 130 is, for example, a Central Processing Unit (CPU) for executing a Basic Input Output System (BIOS) for performing a Power-On Self Test (POST).

The controller 140 is coupled to the memory 110, the substrate management controller 120, and the processor 130. The controller 140 is configured to initialize the memory 110 when the boot self test is performed, and set a plurality of parameters of the sharing space 111. The foregoing parameters are, for example, a base address of the sharing space 111 and a capacity size of the sharing space 111. In the present embodiment, the aforementioned base address is, for example, "E000 000", and the capacity is, for example, 16 MB.

When the controller 140 finishes initializing the memory 110, the sharing space 111 is disabled, that is, the processor 130 cannot access the data of the sharing space 111. Moreover, the controller 140 can adjust, for example, a flag and enable or disable the sharing space 111 according to the flag. For example, if the flag is "1", the controller 140 enables the space 111; if the flag is "0", the controller 140 disables the space 111.

In addition, when the controller 140 completes the initialization of the memory 110, an initial device manufacturing intelligent platform management interface (OEM IPMI) command is generated to the substrate management controller 120 to notify the substrate. The management controller 120 shares the size of the space 111 and establishes initialization settings for the random access memory disk (RAM Disk) and the simple file system for the shared space 111. Next, the controller 140 generates the loaded OEM IPMI command to the baseboard management controller 120, informing it that the relevant execution file is prepared and copying it to the sharing space 111.

When it is judged that the control signal is not received, the controller 140 continues to judge whether the aforementioned control signal is received until the control signal is received.

Thereafter, the baseboard management controller 120 executes the foregoing command file according to the third access signal, and after executing the foregoing command file, generates an execution result to the controller 140. Next, the controller 140 stores the execution result to the sharing space 111, and adjusts the flag to "0", for example, to disable the sharing space 111.

After the processor 130 ends the self-boot test, in an embodiment, the substrate management controller 120 determines whether an interrupt command replacement signal is received, and the interrupt command replacement signal is generated, for example, by a remote device. The interrupt instruction replacement signal is used, for example, to instruct the processor 140 to notify the replacement of some of the sub-interrupt instructions. When it is determined that the interrupt instruction replacement signal is not received, the baseboard management controller 120 continues to determine whether the interrupt command replacement signal is received until it is determined that the interrupt instruction replacement signal is received.

The controller 140 generates a fourth access signal (such as a System Management Interrupt (SMI)) to the processor 130 corresponding to the interrupt instruction, and according to the control signal, for example, the adjustment flag is "1", so as to enable Share space 111. Then, the processor 130 executes a replacement execution file in an interrupt program (for example, an SMI processing program) according to the fourth access signal to perform a replacement operation on some sub-interrupt instructions, and And after the execution is completed, an execution completion signal is generated. Thereafter, the controller 140 disables the sharing space 111 according to the execution completion signal, for example, the adjustment flag is "0".

After the processor 130 ends the self-boot test, in an embodiment, the substrate management controller 120 determines whether a second updated firmware signal is received, and the second updated firmware signal is generated, for example, by a remote device. The second update firmware signal is used, for example, to indicate that the processor 130 needs to update the firmware of the basic input output system. When it is determined that the second updated firmware signal is not received, the baseboard management controller 120 continues to determine whether the second updated firmware signal is received until it is determined that the second updated firmware signal is received.

When it is determined that the second updated firmware signal is received, the substrate management controller 120 stores the second updated firmware corresponding to the second updated firmware signal to the sharing space 111 through the controller 140, and after the storage is completed, generates a The completion signal and a control signal are stored to the controller 140. The controller 140 generates a fifth access signal to the processor 130 according to the storage completion signal, and adjusts the flag to "1" according to the control signal to enable the space 111 to be shared. Next, the processor 130 executes the second update firmware according to the fifth access signal to update the basic input/output system, and after the update is completed, generates an update completion signal. Thereafter, the controller 140 disables the sharing space 111 according to the update completion signal.
