Problems solved by technology

The external card is a small circuit with a programmable device and a seven-segment rainbow display tube. The design is relatively complicated. Each motherboard must be equipped with a connector, which causes a waste of electronic devices.
In addition, every time there is a problem with the server startup, it must be shut down and then connected to an external card for debugging. However, for some random problems, it may be difficult to reproduce after shutdown, which makes debugging inconvenient.

Embodiment Construction

[0027] refer to figure 1 Shown is a schematic view of the operating environment of a preferred embodiment of the BIOS debugging and detection system 10 of the present invention. In this embodiment, the BIOS debugging detection system 10 is installed and run in a computer 100, which includes a BMC (Base management controller) controller 1, a south bridge (Platform controller hub, PCH) chip 2, serial and parallel Converter (Switch) 3, LED panel 4, jumper setting device 5, and central processing unit (CPU) 6. The BMC controller 1 is connected to the PCH chip 2 through the LPC (Low Pin Count) bus 21 , and is connected to the serial-parallel converter 3 through the GPIO bus 31 . The series-parallel converter 3 is electrically connected to the LED panel 4, the LED panel 4 is composed of eight LED indicator lights 40 respectively used to display the logic number "0" and the logic number "1", each LED indicator light 40 is a seven-segment LED display tube. In this embodiment, the c...

Abstract

The invention provides a system and a method for debugging and detecting a BIOS (Basic Input / Output System). The system and the method for debugging and detecting the BIOS are applied to a computer, wherein the computer comprises a BMC (block multiplexer channel) controller, a PCH (Platform Controller Hub) chip, a serial-parallel converter and an LED panel; when the computer performs the POST process, a POST information code generated by the computer performing the POST process is obtained from the PCH chip and the sent to the serial-parallel converter to control an LED indicator light on the LED panel to be displayed; after the computer performs the POST process, a system state code of the computer is obtained from the PCH chip and then sent to the serial-parallel converter to control the LED indicator light on the LED panel to be displayed. With the adoption of the system and the method, testers can directly know the BIOS debugging process.

Description

technical field [0001] The invention relates to a computer BIOS debugging system and method, in particular to a BMC-based BIOS debugging detection system and method. Background technique [0002] Based on the needs of debugging BIOS (basic input-output system, basic input and output system), hardware engineers use two methods to debug BIOS when designing servers. One is the COM port, and the other is the power-on self test (POST) LED indicator. In consideration of product safety, the COM port will generally be removed after the product is mass-produced. In this case, driving the LED becomes the only way for the user to understand the operating status of the BIOS and for the maintenance personnel to debug the BIOS. However, at present, the industry mainly uses an external card to display the BIOS by using the power-on detection LED indicator light to debug the BIOS. The external card is a small circuit with a programmable device and a seven-segment rainbow display tube. Th...
