Abstract: A motherboard testing device applied to a motherboard which includes two memory channels, and a CPU. Each of the two memory channels includes two memory slots. The motherboard testing device includes four memory modules received in the four memory slots, a switching chip, a microcontroller, and a testing module. The switching chip includes four input pins electrically connected to the four memory modules, four output pins electrically connected to the CPU, and a controlling pin electrically connected to the microcontroller. The microcontroller forms a plurality of combination modes of the memory slots by electrically combining the four memory slots, and controls the switching chip to electrically connect memory slots of each combination mode to the CPU. The testing module tests whether the CPU controls the memory modules received in the memory slots of each combination mode to work in proper working modes.

Abstract: A method for controlling peripheral component interconnect express (PCI-E) slots of a computer reads processor configuration information of a PCI-E slot unit from a CMOS chip when the computer boots up, and controls a GPIO interface to output a first control signal to a PCI-E multiplexer according to the processor configuration information, to control a PCI-E slot unit of the computer to connect to one of processors of the computer through the PCI-E multiplexer according to the first control signal. Then the method checks whether the processor connected to the PCI-E slot unit is running normally. In addition, the method controls the GPIO interface to output a second control signal to the PCI-E multiplexer if the processor connected to the PCI-E slot unit is not running normally, to control the PCI-E slot unit to connect to another processor through the PCI-E multiplexer according to the second control signal.

Abstract: A booting method that detects memory modes is applied to a computer-based platform. A dual insertion model is used to extract memory initial data. The system then performs a determination process for installation data and setting the reading mode. The installation data and reading mode are used to update the stored information in the BIOS, and then accomplish the booting procedure of the BIOS. This method enables the computer to operate using different types of memory.
