Problems solved by technology

[0011] Therefore, if you use a debug cable to debug and save the debug information, since the current BIOS debug methods need special software, or additional computer equipment to connect to the wire, these wires are not common materials and are not easy to obtain. In addition, use the debug The method of saving debugging information by cable will take a lot of time, and will significantly affect the execution time of BIOS. In addition, if you need to switch BIOS to debug mode, you need to recompile the BIOS image (image), which causes a lot of inconvenience

Embodiment Construction

[0027] In the method for storing debugging information of the present invention, a file describing the level of debugging information is stored in a USB storage device, thereby determining the type of debugging information required, and storing the debugging information generated before the execution of the BIOS in the USB storage device, thereby releasing computer's memory without using a debug cable, see figure 1 , is a flowchart of a method for storing debugging information in the present invention, as shown in the figure, the method includes the following steps:

[0028] Step 11: storing a default file in the USB storage device, the default file records the debugging level;

[0029] Step 12: Turn on the computer;

[0030] Step 13: Execute the BIOS, and store the first debugging information generated by the BIOS execution at this stage in the memory of the computer;

[0031] Step 14: judging whether the current condition meets the condition that the second debugging infor...

Abstract

The invention provides a debug information storage method comprising the following steps: storing a preset file in a USB storage device before BIOS execution, wherein debug levels are recorded in the preset file; executing BIOS after the computer starts up, and storing the first debug information generated by the BIOS execution in the phase into a computer memory; determining whether the present conditions satisfy outputting conditions of the second debug information, continuously generated in the BIOS execution process, or not; if yes, using the computer to grab the debug level and record the generated debug level value into the computer memory, storing the first debug information into the USB device, releasing the computer memory, and continuously storing the second debug information, corresponding to the debug level value, into the USB storage device; allowing the computer to load the working system when the BIOS execution is finished.

Description

technical field [0001] The invention relates to the field of debugging information storage, in particular to a method for storing debugging information to a USB external device. Background technique [0002] The current UEFI (Unified Extensible Firmware Interface, Universal Extensible Firmware Interface) BIOS (Basic Input / Output System, basic input and output system) collects debugging information in the following ways: [0003] 1. Use USB (Universal Serial Bus, Universal Serial Bus) to collect debugging information [0004] Using this method, UEFI BIOS needs to be compiled into debugging mode first, and then use a USB cable to connect the USB debugging port of the debugging host to the USB port of the host, and the BIOS debugging information is transmitted to the debugging host through the USB cable, and Utilize software to collect debugging information. [0005] 2. Use the serial port to collect debugging information [0006] Using this method, UEFI BIOS needs to be com...
