Abstract: A method for recovering a basic input/output system (BIOS) image file of a computer system is provided. The method includes steps of: controlling a switch unit of the computer system to switch from a first state to a second state when the BIOS image file is to be updated; reading a current BIOS image file so as to store the same as a backup; controlling the switch unit to switch back to the first state; determining whether a command is received within a first predetermined time period when the BIOS image file is successfully updated to a new version of the BIOS image file; and when negative, controlling the switch unit to switch to the second state and writing the backup of the current version of the BIOS image file.

Abstract: When a baseboard management controller (BMC) is used to control a fan speed of a fan unit of a server by executing a firmware with fan parameter data stored in one temporary storage region, the fan parameter data is updated by receiving fan parameter update data and storing the fan parameter update data in another temporary storage region, and updating the fan parameter data using the fan parameter update data after determining that the received fan parameter update data is valid.

Abstract: A method for updating system information of a computer device is provided. The computer device includes a baseboard management controller (BMC) and a non-volatile memory. The method includes steps of: a) upon activation of the BMC, determining whether the BMC is in a power on reset (PoR) state, and obtaining current system information that is associated with the computer device; b) when it is determined that the BMC is in the PoR state, determining whether system information stored in the non-volatile memory conforms with the current system information; and c) when the determination made in step b) is negative, storing the current system information in the non-volatile memory.

Abstract: A storage enclosure connected to a server via an external network and includes a network switch, an expander that is connected to the network switch and that is configured to generate enclosure data that supports a format conforming with SCSI Enclosure Services, and a board management controller (BMC) that is connected to the network switch and the expander. The BMC is configured to translate the enclosure data into enclosure translating data that supports a Redfish® format. The expander is configured to, after generating the enclosure data, transmit the enclosure data through the network switch to the BMC via an internal network. The BMC is configured to translate the enclosure data into the enclosure translating data, and to transmit the enclosure translating data to the network switch. The network switch transmits the enclosure translating data to the server through the external network.

Abstract: A system includes a host and a display. The host includes a programmable logic device (PIP), a baseboard management controller (BMC) and a switch. The PLD performs a power-on procedure based on a power-on sequence code, generates variable character information in the power-on procedure, and fills the variable character information into a variable field in a preset log text file to result in an updated log text file. When it is determined that the power-on procedure is not normally completed, the PLD controls the switch to switch to a debug mode, and transmits a video signal containing debug information corresponding to the updated log text file to the switch so that the video signal is outputted to the display.
