Abstract: A server with a double-firmware storage space and a firmware update method therefor are provided. The server includes a baseboard management controller (BMC) with a control module and an update module, a selection circuit, a first storage circuit, and a second storage circuit. The control module executes a first firmware program from the first storage circuit. The update module stores a second firmware program in the second storage circuit according to a firmware update instruction when the control module executes the first firmware program. The BMC resets after the second firmware program is stored in the second storage circuit. After the BMC is reset, the control module obtains the second firmware program from the second storage circuit and executes the second firmware program.

Abstract: A method for controlling firmware update of a set of serially coupled expanders is implemented by a host computer. The host computer checks whether or not none of the expanders is in a condition of updating firmware. The host computer permits transmission of the firmware update file to a to-be-updated expander when the determination is affirmative.

Abstract: A method for initializing a peripheral component interconnect express (PCI-E) interface card is provided. The method includes: initializing, by a processing unit in a boot procedure according to a preset first value of a flag, a PCI-E interface card inserted in a PCI-E interface slot by using a first initialization parameter included in a basic input/output system (BIOS) code; setting, by the processing unit in the boot procedure according to the initialized PCI-E interface card, the flag to have the first value or a second value; determining, by the processing unit in the boot procedure, whether the initialized PCI-E interface card needs to be reinitialized; and reinitializing, by the processing unit according to the second value of the set flag when the PCI-E interface card needs to be reinitialized, the PCI-E interface card by using a second initialization parameter included in the BIOS code.

Abstract: A motherboard is to be disposed in a local server, and includes a platform controller hub (PCH) that transmits a command associated with read access to image file data, and a baseboard management controller that includes a memory unit and a processor unit which is electrically connected between the memory unit and the PCH. The memory unit stores an image file data associated with boot-up data of the local server. The processor unit receives the command from the PCH, and interprets the command so as to retrieve the image file data stored in the memory unit. The processor unit performs format conversion upon the image file data so as to generate a packet which conforms to protocols of the PCH, and transmits the packet to the PCH.

Abstract: A method for performing automatic system recovery is implemented by a server including a control chipset and a baseboard management controller (BMC). In the method, when a current image file is corrupted, a recovery engine generates an indicator of a version of the current image file and transmits the indicator to the BMC. The BMC then transmits a request for a backup image file to an external electronic device. After the BMC receives file link information of a disk image file from the electronic device, the BMC accesses the electronic device to download the disk image file, and mounts the disk image file as a virtual disk on the BMC. Afterward, the recovery engine replaces the current image file with the disk image file from the virtual disk.
