Abstract

The present invention provides a firmware startup method and device, wherein the firmware startup method includes: initializing the processor core, establishing a basic environment for firmware operation; determining the startup location of the firmware, and constructing upper-layer software transfer parameters according to the startup location; The upper layer software transfers parameters to run the operating system self-starting function in the firmware. The firmware startup method provided by the invention can avoid defects and risks introduced in the firmware development process and improve the stability of the firmware.

Description

technical field [0001] The present invention relates to the technical field of computers, in particular to a firmware startup method and device. Background technique [0002] Firmware (also known as Firmware) is a set of programs that are solidified into the Read-Only Memory (ROM) on the computer motherboard. Small programs, including basic input and output programs, system setting information, power-on self-test programs and system self-starting programs, etc., can realize the initialization of various hardware devices, initialization of cache memory and memory controllers, etc. By starting the firmware, the software and hardware environment of the computer can be brought to a certain state, ready for the final startup of the operating system. [0003] Firmware development not only depends on the architecture of the processor, but also depends on the configuration of the board-level equipment of the computer system. For example, for two different motherboards, if the firmw...
