Below in conjunction with accompanying drawing, to a preferred embodiment of the present invention will be described in detail, should be appreciated that following illustrated preferred embodiment, only for description and interpretation the present invention, is not intended to limit the present invention.
Fig. 2 be the embodiment of the present invention provide BIOS Debugging message is put into the Method And Principle block diagram in hard disk, as shown in Figure 2, step comprises:
Step S201, before BIOS debugging, in hard disc of computer, set up for recording the debugging subregion of BIOS Debugging message.
Further, described debugging subregion can overlap with the existing subregion of hard disc of computer, the boot sector that for example described debugging subregion can be hard disc of computer, can be also hard disc of computer installation WIN OS with system boot partition.
Step S202, after computer booting, start BIOS debugging.
Specifically, first to enter BIOS SETUP setting program, then the Debugging message output intent option producing be selected, Debugging message output intent option is set as to " startup ", to start BIOS debugging.
Step S203, when starting BIOS debugging, BIOS sets up to the information transfer channel of described debugging subregion transmission Debugging message.
Step S204, BIOS write described debugging subregion by the Debugging message producing in start-up course via described information transfer channel, form one or more Debugging message log files.
Described Debugging message log file will constantly record the Debugging message producing in UEFI BIOS start-up course, when the Debugging message amount in a Debugging message log file increases to a certain degree, can cover preceding Debugging message, can be by the new Debugging message log file of regeneration, until the debugging subregion setting in advance in hard disc of computer is write full etc.
Between BIOS limber up period, abnormal if machine occurs, read the Debugging message log file of debugging subregion, slip-stick artist can, by checking the Debugging message while makeing mistakes with analytic engine, effectively carry out positioning problems.
After execution step S204, if do not need to carry out again BIOS debugging, again enter BIOS SETUP setting program, then by the Debugging message output intent option producing is selected, Debugging message output intent option is set as to " closing ", close BIOS debugging, thereby make BIOS in start-up course, stop to described debugging subregion transmission Debugging message.
BIOS stops after described debugging subregion transmission Debugging message, and the Debugging message in described Debugging message log file can not changed.
Fig. 3 be the embodiment of the present invention provide BIOS Debugging message is put into the device block diagram in hard disk, as shown in Figure 3, comprise that debugging subregion sets up that module, BIOS debugging start module, BIOS transmission channel is set up module and BIOS Debugging message writing module.
Described debugging subregion is set up module for before BIOS debugging, in hard disc of computer, set up for recording the debugging subregion of BIOS Debugging message, furtherly, the debugging subregion that described debugging subregion is set up module foundation can overlap with the existing subregion of hard disc of computer, especially, described debugging subregion can be the boot sector of hard disc of computer, can be also hard disc of computer installation WIN OS with system boot partition.
Described BIOS debugging starts module for after computer booting, starts BIOS debugging, specifically, first to enter BIOS SETUP setting program, then the Debugging message output intent option producing is selected, Debugging message output intent option is set as to " startup ", to start BIOS debugging.Further, described BIOS debugging starts module can also not need to carry out BIOS debugging again, close BIOS debugging, specifically, first to again enter BIOS SETUP setting program, then the Debugging message output intent option producing is selected, Debugging message output intent option is set as to " closing ", to close BIOS debugging, when closing BIOS debugging, delete the information transfer channel to described debugging subregion transmission Debugging message that BIOS sets up, like this, BIOS, will be no longer to described debugging subregion transmission Debugging message in start-up course.
Described BIOS transmission channel is set up module for when starting BIOS debugging, and BIOS sets up to the information transfer channel of described debugging subregion transmission Debugging message.
Described BIOS Debugging message writing module writes described debugging subregion for the Debugging message that start-up course is produced via described information transfer channel, forms one or more Debugging message log files.Wherein, described Debugging message log file will constantly record the Debugging message producing in UEFI BIOS start-up course, when the Debugging message amount in a Debugging message log file increases to a certain degree, can cover preceding Debugging message, can be by the new Debugging message log file of regeneration, until the debugging subregion setting in advance in hard disc of computer is write full etc.Between BIOS limber up period, abnormal if machine occurs, read the Debugging message log file of debugging subregion, slip-stick artist can, by checking the Debugging message while makeing mistakes with analytic engine, effectively carry out positioning problems.Debugging message in described Debugging message log file stops can not changing after described debugging subregion transmission Debugging message at BIOS.
Take certain computing machine as example, and the flow process that BIOS Debugging message is put in hard disk is as follows:
In a, the hard disk that is equipped with at this computer equipment, mark separately a debugging block, be referred to as to debug subregion.
Described debugging subregion can overlap with the existing subregion of hard disc of computer, for example debug boot sector that subregion is hard disk or install WIN OS with system boot partition in.
B, UEFI BIOS no longer distinguish debugging mode and normal mode, only need in BIOS SETUP setting program, add an option.
The project name of described option is " Debugging message output ", is divided into two options: " startup " and " closing ".
C, by BIOS SETUP setting program, by " Debugging message output " set of options, be " startup ", then UEFI BIOS can be Debugging message by all log-on messages, outputs in the debugging subregion in this machine hard disk, generates one or several Debugging message log file.
That is to say, BIOS, when start, can read the parameter setting in BIOS SETUP, if find that the parameter setting is set as " startup ", just can directly read and write hard disk sector.For modern BIOS, the read-write program that has wrapped into hard disk sector, that is to say, when starting BIOS debugging, BIOS can set up to the information transfer channel of described debugging subregion transmission Debugging message, and utilizes described information transfer channel to read and write hard disk sector.
Further, described Debugging message log file can constantly record the Debugging message producing in UEFI BIOS start-up course, can there is various ways to be chosen by BIOS deviser, for example, when Debugging message amount increases to a certain degree, be to cover again former debugging recording, override, still produce again new Debugging message log file, until write the full debugging subregion setting in advance etc. in hard disk.
Same, also can by " Debugging message output " set of options, be " closing " by BIOS SETUP setting program, for example when not needing to carry out BIOS debugging, close BIOS debugging, now, UEFI BIOS no longer exports any Debugging message in starting, and naturally also can not change Debugging message log file.
Visible, it is " Debugging message output " that BIOS need add an option, this project name in BIOS SETUP setting program, is divided into two options, " startup " and " closing ".The present invention has revised present UEFI BIOS pattern compiler, and whether existing pattern is to utilize an overall switch in the appointment of when compiling to control Debugging message to be compiled in BIOS ROM and gone.The present invention is when UEFI BIOS output Debugging message, no longer rely on overall switch, but need check " Debugging message output " the option numerical value providing in BIOS SETUP setting program, " if startup ", export Debugging message in the Debugging message log file in the debugging subregion of the machine hard disk, if " close ", no longer export Debugging message.
In sum, no matter while being the equipment batch testing before computing machine dispatches from the factory, or while occur starting the situation such as abnormal after computing machine dispatches from the factory, can by " Debugging message output " set of options, be " startup " by BIOS SETUP setting program, BIOS Debugging message is written to the Debugging message log file of debugging subregion, thereby when equipment is made mistakes, by reading and analyze the Debugging message in the Debugging message log file of described debugging subregion, fast and effectively decision problem place.
Although above the present invention is had been described in detail, the invention is not restricted to this, those skilled in the art of the present technique can carry out various modifications according to principle of the present invention.Therefore, all modifications of doing according to the principle of the invention, all should be understood to fall into protection scope of the present invention.
