BIOS (/ˈbaɪɒs/ BY-oss; an acronym for Basic Input/Output System and also known as the System BIOS, ROM BIOS or PC BIOS) is firmware used to perform hardware initialization during the booting process (power-on startup), and to provide runtime services for operating systems and programs. The BIOS firmware comes pre-installed on a personal computer's system board, and it is the first software to run when powered on. The name originates from the Basic Input/Output System used in the CP/M operating system in 1975. The BIOS originally proprietary to the IBM PC has been reverse engineered by companies looking to create compatible systems. The interface of that original system serves as a de facto standard.

An auto-switching BIOS system and the method thereof, switches to dual BIOS by a hardware control circuit. After the system has been started with the first BIOS to the predetermined period of time and the BIOS_READY signal is detected as disabled, the hardware control circuit switches the system from the first BIOS to the second BIOS and restarts the system with the second BIOS.

The embodiment of the invention discloses an establishing method and system of a trust chain. The method comprises the steps of starting a BMC module and a TCM module before a server is powered on; adopting the TCM module to scale BMC firmware in the BMC module to obtain a first scaling result, and judging whether or not the BMC firmware is tampered according to the first scaling result; if the BMC firmware is not tampered, adopting the BMC firmware to scale BIOS-Boot-Block to obtain a second scaling result, and judging whether or not the BIOS-Boot-Block is tampered according to the second scaling result; if the BIOS-Boot-Block is not tampered, controlling a power control module to power on the server, and adopting a BIOS to establish the subsequent trust chain. According to the establishing method and system of the trust chain, the safety of the trust chain is improved when the trust chain is established, and accordingly the safety of the system is improved.
