Abstract:
1. A motherboard system, comprising: a central processing unit (CPU); a control unit, electrically connected to the CPU; and a Peripheral Component Interconnect (PCI) Express connector, electrically connected to the control unit, wherein the PCI Express connector having a boot loader interface unit and a peripheral storage device interface unit, wherein the boot loader interface unit is electrically connected to the control unit and is configured for connecting a system read only memory (ROM) and the peripheral storage device interface unit is a PCI Express interface bus, wherein the CPU sends a ROM fetch cycle to the control unit and fetches a booting program from the system ROM via the boot loader interface unit, wherein the PCI Express connector comprises: a first pin, configured to receive an input signal corresponding to a serial peripheral interface (SPI) standard; a second pin, configured to receive an output signal corresponding to the serial peripheral interface standard; a third pin, configured to receive a clock signal corresponding to the serial peripheral interface standard; and a fourth pin, configured to receive a chip select signal corresponding to the serial peripheral interface standard, wherein the boot loader interface unit is consisted of the first pin, the second pin, the third pin, and the fourth pin.
