ABSTRACT:
A basic input output system (BIOS) selection device is applicable in an electronic device. The BIOS selection device includes a storage unit and a control unit, which are mounted on a mainboard of the electronic device. The storage unit includes a first chip and a second chip, each of which includes a primary BIOS module and a secondary BIOS module. The control unit includes a signal module for producing a first chip selection signal and a second chip selection signal, and a switch module having a first switch component and a second switch component. The BIOS selection device can realize two dual BIOS mechanisms on the same mainboard for a user to select one of the dual BIOS mechanisms to boot the electronic device without having to purchase another mainboard for using a different dual BIOS mechanism unlike the prior art.
