Zusammenfassung: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.
