Auto-Switching Bios System and the Method Thereof

[0012]Reference will now be made in detail to the present embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers are used in the drawings and the description to refer to the same or like parts.

[0013]Refer to FIG. 1. FIG. 1 illustrates the first example of the preferred embodiment of this invention. As shown in FIG. 1, the system 100 of auto-switching BIOS comprises a hardware control circuit 110, a central processing unit 120, a power supply unit 130, a switch circuit 140, and a BIOS ROM 150, wherein the BIOS ROM 150 stores the first BIOS program 151 and the second BIOS program 152. The hardware control circuit 110 is a programmable logic integrated circuit. After the system 100 has been started to a predetermined period of time, the hardware control circuit 110 detects the BIOS_READY signal. If the BIOS_READY signal is disabled, the hardware control circuit 110 sends out a switch signal to the swit...
