Abstract
The invention discloses an information processing method, which is used for improving the security of the communication between the basic input output system and the released program. The method includes: controlling the central processing unit to be in a working state; loading the BIOS of the firmware unit, so that the BIOS enjoys the control right; during the process that the BIOS enjoys the control right, the BIOS releases a predetermined program unit into the memory, the predetermined program unit is a subunit pre-set in the BIOS; when the central processing unit controls the BIOS to hand over the control right to the OS, the central The processor controls to load the predetermined program unit during the loading process of the OS, and the predetermined program unit executes M function items, where M is an integer greater than or equal to 1. The invention also discloses electronic equipment for realizing the method.
Description
technical field [0001] The invention relates to the technical field of computers, in particular to an information processing method and electronic equipment. Background technique [0002] In the prior art, the basic input output system (Basic Input Output System, BIOS) is a set of programs solidified on a ROM (Read Only Memory) chip on the motherboard of the computer, which stores the most important basic information of the computer. The main function of the input and output program, system setting information, self-test program after power-on and system self-starting program is to provide the lowest-level and most direct hardware setting and control for the computer. [0003] In the prior art, after the basic input and output system is loaded, for example, after the POST is completed, the operating system OS loads the kernel, drivers, and services during the loading process to complete the loading and running of the operating system. [0004] In the prior art, the operatin...
