Computer system booting earlier stage debugging device and method thereof

Abstract

The invention discloses a debugging device and its method before the computer system started which adopts accelerating collectrator structure. It comprises a computer system with PCI bus to debug before the computer started which has PIC surface interface, programmable integrated chip, BIOS register and LED display, wherein PIC surface interface is connected with a testing computer system's PIC interface; programmable integrated chip is connected with PIC surface interface, which has the same address with BIOS of testing computer system and can controls the replaced testing computer system's BISO operation by control program to achieve computer system auto testing and analyzes the malfunction of testing computer system; it displays the malfunction code at LED display and storages the control program into BIOS register.

Description

technical field [0001] The invention relates to a computer system debugging system, in particular to a computer system startup debugging device and method thereof. Background technique [0002] Generally speaking, a computer system architecture includes a central processing unit, an input device, an output device, a memory, etc., and these components are connected, data transmitted, and controlled through a bus. [0003] In the above-mentioned computer system architecture, no matter in the research and development stage of the computer motherboard or in the maintenance stage, it is possible to perform the debugging function on the computer system. Since the operation of the computer system involves quite complex functional instructions, computer engineers can analyze the cause of errors in the computer system with the help of debuggers. However, in general debugging procedures, the debugging function can only be performed after the computer under test is started up normally...

[0005] Therefore, for the computer system that adopts the above-mentioned structure, because the previous startup card or fault analysis card does not support the computer system structure, when the system cannot start or other failures, it cannot be analyzed by using the previous startup card or fault analysis card. and identify system failures

Moreover, for a computer system using an accelerated hub structure, if the computer system fails, a general computer engineer can start the computer system and enter the operating system to perform system self-debugging, so that the computer engineer can easily and conveniently find out the system failure; but When the computer system fails to start up and enters the self-debugging operating system, the computer engineer needs to conduct a large-scale inspection of the entire computer system to analyze the fault. This method is time-consuming and labor-intensive, and the efficiency of analyzing the fault is relatively low. Not conducive to failure analysis of computer systems
