Abstract
A computer has a first BIOS unit, a second BIOS unit, a bus, a detecting unit, and a first delay unit. The detecting unit is connected to the bus, the first BIOS unit, and the second BIOS unit operationally. In addition, the first delay unit is electrically connected to the detecting unit for controlling the detecting unit to check a status of a bus signal on the bus after a predetermined delay time. Accordingly, the detecting unit may enable the first BIOS unit or the second BIOS unit to boot the computer system according to the state of the bus signal.
Claims7
A computer system, comprising:
- a first basic input output system (BIOS) unit to boot the computer system;
- a second BIOS unit;
- a bus;
- a detecting unit, operationally connected to the bus, the first BIOS unit and the second BIOS unit for detecting a bus signal on the bus;
- and
- a first delay unit, electrically connected to the detecting unit, for enabling the detecting unit after a predetermined delay time, so that the detecting unit enables the second BIOS unit to reboot the computer system according to checking a state of the bus signal in an abnormal booting state, wherein the detecting unit further has a clear terminal electrically connected to the first delay unit to receive a clear signal, and a preset terminal disabled.
