A motherboard test device includes a motherboard and a connection module. The motherboard includes a basic input output system (BIOS) chip, a complex programmable logic device (CPLD) chip, and a motherboard connector. The connection module includes a test connector connected to the motherboard connector, a first port connected to random access memory (RAM) of the BIOS chip, and a second port connected to the CPLD chip. A RAM simulator updates or tests BIOS programs stored in the RAM by connecting to the first port. A personal computer (PC) can electronically communicate with the CPLD chip by connecting a parallel interface of the PC to the second port.
