Description

Technical Field

[0001] This utility model relates to the field of PC motherboard server development and debugging technology, and in particular to a server remote BIOS debugging system. Background Technology

[0002] With the development of cloud gaming, cloud esports, and other applications, a new type of PC Farm server has emerged, featuring a stacked device architecture. It deploys traditional PC motherboards in standard racks, achieving computing power second only to data centers at a relatively low cost and high flexibility. During the development and debugging of PC motherboards, it is necessary to update the BIOS (Basic Input / Output System), install the operating system, and other methods to troubleshoot and resolve testing issues. Printing BIOS debug logs is also crucial for locating problems and developing new features.

[0003] On server motherboards equipped with a BMC (Baseboard Management Controller) system, BIOS upgrades, debugging, and system installation can be performed via network. However, ordinary PC motherboards do not have a BMC system and cannot perform remote BIOS debugging via network. Therefore, we propose a remote BIOS debugging system for servers. Utility Model Content

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention utilizes the HDMI capture function of the control box via an HDMI cable to display the PC motherboard's image output interface in real time. The debugging terminal accesses the control box's web page to upload the BIOS and UEFI boot system to the control box. Using the control box's OTG interface, it simulates a USB flash drive and USB keyboard / mouse, connecting to the PC motherboard via a USB cable. After the PC motherboard restarts, it enters the UEFI system, and the BIOS is updated using tools. Similarly, the debugging terminal can also access the control box's web page to upload a system image to the control box. Utilizing the control box's OTG interface, it simulates a USB flash drive and USB keyboard / mouse, connecting to the PC motherboard via a USB cable. After the PC motherboard restarts, it enters the system installation process. A serial port connection is used to capture the serial port print information of the PC motherboard's BIOS during the boot process, enabling rapid BIOS problem location and debugging.
