Abstract
A computer motherboard selectively uses various memories in the light of a dummy card. The computer motherboard comprises a serial resistor, and a first slot and a second slot for holding various memories, respectively. Various memories can be configured on the motherboard without additional settings by means of predefined dummy card or/and rearranging the location of the serial resistor.
