Abstract
An embodiment method for reading a BIOS includes receiving a reset signal of a processor, and generating a first start address or a second start address according to the reset signal, and reading a BIOS in a storage chip according to the first start address or the second start address. The first start address corresponds to a storage address of a primary BIOS stored in the storage chip, and the second start address corresponds to a storage address of a backup BIOS stored in the storage chip. When reading the BIOS, the processor may generate the first start address or the second start address according to the reset signal, so as to read the primary BIOS or the backup BIOS, which may improve universality of BIOS reading.

A method for reading a basic input output system (BIOS), comprising:
- receiving, by a processor, a reset signal of the processor;
- generating, by the processor, a first start address or a second start address according to the reset signal;
- and
- reading, by the processor, the BIOS in a storage chip according to the first start address or the second start address, respectively,
- wherein the first start address corresponds to a first storage address of a primary BIOS stored in the storage chip, and the second start address corresponds to a second storage address of a backup BIOS stored in the storage chip.
A processor comprising:
- a reset signal pin, configured to receive a reset signal;
- a start address generating module, configured to receive the reset signal from the reset signal pin, and generate a first start address or a second start address according to the reset signal;
- and
- a basic input output system (BIOS) reading module, configured to read a BIOS in a storage chip according to the first start address or the second start address, respectively, wherein the first start address corresponds to a first storage address of a primary BIOS stored in the storage chip, and the second start address corresponds to a second storage address of a backup BIOS stored in the storage chip.
A computer system, comprising:
- a processor comprising
- a reset signal pin, configured to receive a reset signal;
- a start address generating module, configured to receive the reset signal from the reset signal pin, and generate a first start address or a second start address according to the reset signal;
- and
- a basic input output system (BIOS) reading module, configured to read a BIOS in a storage chip according to the first start address or the second start address, respectively, wherein the first start address corresponds to a first storage address of a primary BIOS stored in the storage chip, and the second start address corresponds to a second storage address of a backup BIOS stored in the storage chip;
- and
- the storage chip, coupled to the processor, and configured to store the primary BIOS and the backup BIOS.
