Abstract
A method, apparatus and storage medium for starting up peripheral component interconnect express (PCIE) device are provided. According to the method, a basic input/output system (BIOS) attempts to verify firmware of a PCIE device to determine whether the firmware of the PCIE device is tampered with. Moreover, the BIOS may only start up a PCIE device with firmware that succeeds in the verification. Therefore, a computer device is prevented from starting up a PCIE device with firmware that is tampered with, thereby reducing the security risk caused by the PCIE device to the computer device.
