Technical Field

Background

The BIOS (Basic Input/Output System), i.e. the Basic Input/Output System, is mainly responsible for initializing computer hardware and booting the operating System, and plays a very important role in the computer System. However, as the computer industry rapidly develops, CPUs (central processing units) and other hardware devices are continuously updated, and the BIOS gradually becomes a bottleneck of system development. Mainly manifested by low development efficiency, poor performance, poor function expansibility, slow upgrade, security problem and no support for booting from an address above the hard disk 2 TB.

Based on the above limitations, uefi (unified Extensible Firmware interface), which is a new standard, was created, and defines an interface between an operating system and platform Firmware. Due to the birth of UEFI, the BIOS is greatly applied and developed. The BIOS used at present is based on the UEFI standard, and hereinafter, if not specifically described, the BIOS is collectively referred to as UEFI BIOS.

In a POST (power on self test) stage, the BIOS prints a large number of start logs through serial ports to display the current start stage and the initialization state of each stage of the platform. The BIOS code may control whether these logs are compiled into Image (Image file). If the BIOS starts a Debug function, compiling a Debug Log and printing through a serial port during POST; if the BIOS closes the Debug function, the Debug Log cannot be compiled, and no Log is printed during POST.

In the prior art, if logs with different debugging levels are needed, Debug Mode (debugging Mode) needs to be frequently turned on or turned off, and the BIOS Image needs to be recompiled and the BIOS needs to be burned and updated every time, which is tedious in operation and takes a lot of time.
