Abstract

The present invention is detection and display method and device for computer self-test information. The method includes in the power-on self test (POST) state executing curing program in the BIOS in the POST stage of computer system to send POST information in certain data structure to controller chip and transmit the information to the display module timely so as to display the POST procedure and information in characters and sentences; and displaying fault information, if any, in the display module. The device for the detection and display includes a controller connected to the system control bus of the computer mainboard to obtain POST information; and a display module connected to the controller to display real-time POST information. The present invention makes it possible to display POST information conveniently and intuitively.

Description

technical field [0001] The present invention relates to a method and device for detecting and displaying computer-related information, especially a method and device for detecting and displaying computer power-on self-test (POST) information. Background technique [0002] The concept of the computer POST process refers to the self-test process performed by the basic input and output system (BIOS) of the computer to each module of the computer itself when the computer equipment is powered on. POST information refers to various information obtained by BIOS checking each module during the POST process, including: whether each module exists, whether the status of each module is normal, whether the initialization is completed normally, CPU type, CPU main frequency, memory type, memory capacity , hard disk capacity, BIOS version information and computer serial number, etc. [0003] With the continuous improvement of the computer industry level and the increasing dependence of hum...
