Patent attributes
A motherboard assembly of a computer includes a motherboard (80) and an expansion device. The expansion device is connected to the motherboard. The expansion device includes a BIOS chip (10), a first connector (20) and at least one second connector (30). The first connector is connected to a socket (40) mounted on the motherboard. The second connector is capable of connecting to a burning device (90) for restoring the BIOS chip. The BIOS chip is connected to the first connector, the second connector, and to a signal choice terminal of the motherboard which acts to access the BIOS chip through the first connector and the socket such that the BIOS chip of the expansion device can replace a BIOS chip mounted on the motherboard to be accessed when the computer is powered up to be tested, thereby protecting the BIOS chip mounted on the motherboard being damaged in test.
