In order to explain technical contents, achieved objects, and effects of the present application in detail, the following detailed description is given with reference to the embodiments and the accompanying drawings.
The BIOS (Basic Input Output System) is a program that is fixed to a ROM chip on a computer motherboard and stores a program for Basic Input and Output, a power-on self-test program, and a System self-boot program that are the most important of the computer. When the computer is started, the BIOS can perform scanning detection, equipment initialization, resource allocation and adaptation on hardware on the mainboard, and if the system is down or other system faults occur, the BIOS logs can be acquired to analyze the problems so as to determine the reasons of the faults. Therefore, the application discloses a method for storing BIOS logs of an electronic device, so as to improve the efficiency of collecting the BIOS logs.

The serial log is mainly generated in a Power On Self Test (POST) process of a BIOS system.
And S2, storing the serial port log generated in the running process of the BIOS system in a memory of the electronic device.
Referring to fig. 2, specifically, step S2 includes:
and S21, applying a section of memory to the memory of the electronic device as a storage area for storing the serial port log.
Specifically, the applied memory is at least larger than the maximum capacity required to be occupied by the serial log, and the memory of the electronic device should be occupied as little as possible. Preferably, a segment of memory requested for may be 8 MB.
S22, recording the address of the storage area.
And S23, storing the serial port log in the storage area according to the address of the storage area.
After the serial log of the BIOS system is generated, the serial log is stored in the storage area according to the address of the storage area, the serial log does not need to be output from the serial port in real time in the starting process of the system, and the starting speed of the system can be improved.
It is understood that the electronic device referred to in this application may be a personal computer, a server, or other electronic terminal with a BIOS system, and is not limited in this application.
And S3, the serial port log stored in the memory is transferred to an external memory connected to the electronic device.
It should be understood that the peripheral storage may be a mobile hard disk, a usb disk, or other devices with a storage function, as long as the peripheral storage can be connected to the electronic apparatus and can store the serial log, and the application is not limited herein.
Specifically, the peripheral memory may be connected to the electronic device through a USB interface, and when the peripheral memory is connected to the electronic device through the USB interface, the USB driver of the electronic device may identify the peripheral memory, so that the electronic device performs data communication with the peripheral memory.
Referring to fig. 3, specifically, step S3 includes:
and S31, running the preset program to generate a dump command.

Specifically, the serial log may be stored in the same directory as the preset program.
Further, the preset program is an EFI application program that has been compiled, and the EFI application program may be run in a shell environment of the BIOS system, specifically referring to fig. 8, and compiling the code shown in fig. 8 may generate the preset program for collecting and storing the serial log in the electronic device.
Specifically, after the BIOS system is subjected to power-on self-test, the shell environment may be entered, and a preset program located in the peripheral memory may be selected in the shell command window to be executed.
And S32, according to the unloading command, unloading the serial port log stored in the memory to a peripheral memory connected to the electronic device.

Specifically, referring to fig. 5(a), fig. 5(a) is a schematic diagram of codes defining HOB; the HOB is a structure body for transferring information from the PEI phase to the DXE phase, and data collected in the PEI phase needs to be stored in the HOB if the data needs to be transferred to the DXE phase.
Specifically, referring to fig. 5(b), fig. 5(b) is a schematic diagram of codes for storing serial logs in the HOB, where the codes in the diagram replace original serial log printing functions, so that original serial logs output from the serial port can be stored in the HOB.
