Abstract

The invention provides a debugging method of a basic input / output system. The debugging method comprises the following steps: firstly, a debugging program is preset in a start-up program; next, the basic input / output system implements the start-up program; then whether a state value is a default value of the debugging program is judged according to the debugging program; in the previous judgment, if the state value is the default value, a value to be measured is sent according to the debugging program; and if not, the debugging program is stepped out and the basic input / output system implements the start-up program continuously. The debugging method is used for carrying out detection and debugging of a BIOS chip without needing complicated plugging / pulling actions, thus accelerating the time of detection and debugging and saving the utilization rate of the components.

Description

technical field [0001] The invention relates to a method for debugging a basic input and output system, in particular to a method for debugging a basic input and output system (BIOS) by utilizing temperature changes or output states of general input / output buttons. Background technique [0002] A basic input / output system (BASIC INPUT / OUTPUT SYSTEM; BIOS) of a computer device can read and write random access memory (RAM) made of CMOS. The BIOS learns the operating configuration of the current computer device by reading and writing the CMOS, or records the setting values ​​of certain computer configurations into the CMOS, and makes appropriate boot environment settings. [0003] Generally speaking, during the boot process of the basic input output system (BIOS) of the computer device, the boot program (boot program) will send a special code (code) through an input / output port address 80H every other program, and This special code will be read by a debug monitor card (port 80...
