The application provides a kind of method and device that carries out data recovery, in order to solve in prior art, exists owing to losing when boot block data or when part damages, can not automatically realize the technical matters of boot block data recovery.
Technical scheme in the embodiment of the present application is for solving the above-mentioned technical matters that can not automatically realize boot block data recovery, and general thought is as follows:
When electronic equipment is when starting the operating system, can first detect the first log-on data in the first memory that Basic Input or Output System (BIOS) controls and be in can read state or can not reading state, when the first log-on data is when can read state, electronic equipment just can normally start the operating system, thereby, can operate normally and use electronic equipment; When the first log-on data is in can not reading state time, electronic equipment will be enabled the second log-on data being stored in second memory, namely by a controller of electronic equipment, control the second log-on data being stored in second memory is stored in basic input and output bootstrap block, make boot block data be restored (said first memory just refers to basic input and output bootstrap block, and the first log-on data refers to the boot block data being stored in bootstrap block) here.
In order better to understand technique scheme, below in conjunction with Fig. 1 and Fig. 2 and concrete embodiment, technique scheme is described in detail.
The embodiment of the present invention provides a kind of method of carrying out data recovery, is applied in an electronic equipment, and in concrete application, described electronic equipment can be specifically: notebook computer, and desktop computer, panel computer, in this application, does not do concrete restriction.Described electronic equipment comprises operating system, and the Basic Input or Output System (BIOS) for starting the operating system.
In the embodiment of the present application, carry out the specific implementation process of method of data recovery as follows:
Step S10: in os starting process, detect the first log-on data in the first memory that is stored in electronic equipment that Basic Input or Output System (BIOS) is used for starting the operating system and be in can read state or can not reading state.
In concrete implementation process, in os starting process, be first by detecting the first log-on data, when the first log-on data can successfully be read, just can normally start; When the first log-on data breaks down, as: corrupted data or loss etc., just cause the phenomenon that cannot read the first log-on data, now, the data in bootstrap block are the state in not can read just, so just just causes and cannot start the operating system.
Take below electronic equipment as computing machine be example, step S10 is described in detail.
Specifically, implementation procedure is as follows: in os starting process, as shown in Figure 2, Basic Input or Output System (BIOS) (BIOS) can go to read BIOS SPI ROM 104(ROM of BIOS) in the first log-on data, if the first log-on data can successfully be read, so now the first log-on data is just in can read state; If while reading, due to reasons such as log-on data damages, to cause data to read unsuccessful, and the first log-on data so is now the state in not can read just.When the state of data in not can read, there will be BIOS SPI ROM 104 unaltered phenomenons.
In step S10, detect Basic Input or Output System (BIOS) and whether can from first memory, read acquisition the first log-on data, specific implementation can be: detect Basic Input or Output System (BIOS) and whether can in a Preset Time, from first memory, read acquisition the first log-on data.
In specific embodiment, when Basic Input or Output System (BIOS) reads the first log-on data in BIOS SPI ROM 104, SPI(Serial Peripheral Interface (SPI)) can start a timing module, if within the predetermined time, the basic input and output bootstrap block of BIOS code() do not change, so just think that the first log-on data is in can not reading state.First, the phenomenon computing machine that cannot be read due to the first log-on data can be waited for and reading, if the overlong time that cannot be read, and computing machine is for a long time in waiting status, so this state is all to want consumed power concerning computing machine or other electronic equipment, in order to address this problem, technical scheme in the embodiment of the present application can start a timing module, if within the predetermined time, data are the state in being read still, and computing machine can take immediate steps to eliminate this state.The measure of taking as: stop the process that reads to the first log-on data, searching can substitute the data of the first log-on data.The measure of taking as described herein namely can be introduced in detail in step S20.
