Problems solved by technology

[0003] Generally speaking, in the early stage of POST, the hardware related to the operation of the computer, such as the central processing unit (CPU), memory, and motherboard, will be detected first, and the display card will be initialized and tested in the middle stage; In the early stage, if the BIOS program detects a hardware error, the user cannot see the debugging information related to the hardware error generated by the BIOS program on the screen connected to the graphics card, which also causes system developers Hardware errors detected in the early stages of POST are not easily ruled out during the process
[0004] In addition, if the BIOS program detects a hardware error after the graphics card is initialized, the debug information displayed on the screen through the BIOS program to control the graphics card is usually only a debug code (debug code), and does not provide information related to the hardware error. a detailed description of

Embodiment Construction

[0016] refer to figure 1 As shown, the method for displaying BIOS information in the early stage of the computer system self-test is implemented by a computer system. The computer system includes a computer host 1 and a screen 2. The computer host 1 includes a processing unit 11 and a substrate. A management controller 12 (Baseboard Management Controller), a memory unit 14 electrically connected to the processing unit 11 , and a display unit 13 . In this embodiment, the display unit 13 is a display card and is electrically connected to the screen 2 ; the BMC 12 is electrically connected to the processing unit 11 and the display unit 13 . The memory unit 14 is, for example, a read-only memory, and stores a BIOS program module 141 .

[0017] refer to figure 2 As shown, an embodiment of the method for displaying BIOS information in the early stage of computer system POST will be described in detail below.

[0018] After the host computer 1 starts, the baseboard management con...

Abstract

The invention provides a method for displaying BIOS (Basic Input Output System) information at the early stage of power-on self-test of a computer system. The computer system comprises a processing unit, a baseboard management controller, a BIOS program module and a display unit, the method comprises the steps that the baseboard management controller initializes the display unit; the processing unit generates BIOS information by executing the BIOS program module; the processing unit transmits the BIOS information to the baseboard management controller; and the baseboard management controller outputs the BIOS information to the display unit.

Description

【Technical field】 [0001] The invention relates to a method for displaying BIOS information when a computer system starts self-test, in particular to a method for displaying BIOS information at an early stage after system startup. 【Background technique】 [0002] After the computer is powered on and started, the computer will execute the BIOS program to detect each hardware of the computer, which is the so-called power-on self-test (Power-On Self-Test, POST); and in the process of power-on self-test If a hardware error is detected, the computer will continue to perform POST or stop operating depending on the type of hardware error. When some specific hardware errors occur, the BIOS hang may occur and the computer cannot continue to boot, and the computer will stop working at this time; After the debug code is displayed, POST continues. [0003] Generally speaking, in the early stage of POST, the hardware related to the operation of the computer, such as the central processin...
