Problems solved by technology

However, if the BIOS data is damaged, such as user error, power interruption or software failure, etc., the computer cannot be guided to the corresponding operating system, and the BIOS refresh cannot be completed.
[0005] When the BIOS data is damaged, if you want to continue to refresh the BIOS or restore the existing BIOS data, you can only remove the BIOS chip in the prior art and put it on the burner to re-enter the existing BIOS data. BIOS data or updated BIOS data, the operation process is cumbersome

Embodiment 1

[0058] The flow chart of the refreshing / restoring method disclosed in this embodiment is as follows: figure 1 As shown, the method is applied to an electronic device, and the electronic device includes a first storage unit, a second storage unit and a control unit, and the first storage unit is used to store The first data initialized by hardware; the second storage unit is used to store the second data, and the second data includes the first data and / or an updated version of the first data; the control unit can pass The bus establishes a connection relationship with the first storage unit and the second storage unit;

[0059] The method includes the following steps:

[0060] Step S101: the control unit obtains an operation instruction instructing to refresh / restore the first data;

[0061] Wherein, the manner in which the control unit obtains the operation instruction may be to actively obtain the above operation instruction, or to passively receive external information to ...

Embodiment 2

[0080] The flow chart of the refreshing / restoring method disclosed in this embodiment is as follows: image 3 As shown, this embodiment adds step S204 on the basis of the previous embodiment: after the control unit writes the second data into the first storage unit, disconnect the control unit from the first storage unit. A data transmission path between storage units, so as to facilitate the normal operation of the next refresh / recovery work.

[0081] Still taking the refresh / recovery of the computer BIOS program with EC and EC Flash as an example, the working process of this embodiment is:

[0082]When the BIOS is damaged or needs to be refreshed, the system sends an operation instruction indicating to refresh / restore the BIOS program to the EC. After the EC obtains the operation instruction, it connects to the BIOS Flash and the EC Flash through the SPI bus or other channels, and disconnects the BIOS Flash from the PCH at the same time. Or the connection of ICH, so as to e...

Embodiment 3

[0091] The flow chart of the refreshing / restoring method disclosed in this embodiment is as follows: Figure 4 As shown, the difference between this embodiment and the previous embodiment is that after the data transmission path between the control unit and the first storage unit and the second storage unit is established, before refreshing / recovering the first data, an additional Step S303: judging whether the first data is damaged and / or whether the first data has been updated, if yes, proceed to step S304, otherwise, proceed to step S305;

[0092] Step S304: Start the refresh / restoration function to refresh / recover the first data, that is, the control unit reads the second data in the second storage unit, and transfers the first data to the second data through the data transmission path. The corresponding data in the two data is written into the first storage unit to replace the first data, so as to realize the refresh / restoration of the first data;

[0093] Step S305: It ...

Abstract

An embodiment of the invention discloses a refreshing / recovering method and electronic equipment. The electronic equipment comprises a first storage unit, a second storage unit and a control unit. The method includes the steps: utilizing the control unit to acquire operation instructions for instructing to refresh / recover first data; utilizing the control unit to set up data transmission paths between the control unit and the first storage unit and between the control unit and the second storage unit; and utilizing the control unit to read second data in the second storage unit, and writing the corresponding data in the second data into the first storage unit through the data transmission path to substitute for the first data, so that the first data are refreshed / recovered. By the aid of the refreshing / recovering method and the electronic equipment in the embodiment, during refreshing / recovering of initialized data, a storage tool stored with the initialized data does not need to be subjected to complicated processes such as being burned again and the like, but the data are directly read and written inside the electronic equipment, so that the refreshing / recovering process of the initialized data is more convenient, simpler and quicker.

Description

technical field [0001] The present invention relates to the field of computers, and more specifically, to a refreshing / restoring method and an electronic device. Background technique [0002] In electronic equipment, hardware initialization is generally performed during the startup process, but once the data stored in the electronic equipment to initialize the hardware is damaged, the initialization process cannot continue, resulting in the electronic equipment not operating normally. To refresh or restore the initialization data, the operation process is relatively cumbersome. [0003] Taking a computer as an example, the BIOS (Basic Input Output System) in the computer is a set of programs solidified into the ROM chip on the computer motherboard, which stores the most important basic input and output system of the computer. Programs, system setting information, power-on self-test programs and system self-starting programs, etc., provide the lowest and most basic hardware ...
