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.

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: An anti-tamper system includes a first object, second objects, and an anti-tamper circuit that includes conductive networks and a control unit. Each conductive network includes: conductive modules, each of which is sandwiched between the first object and a corresponding second object; and conductive connection members which are coupled to the conductive modules in such away that at least the conductive modules and the conductive connection members cooperatively form a corresponding electrical path sequentially going through the second objects. The control unit detects damage of each electrical path, and initiates a predetermined action upon detecting the damage.
