In practical application, if the picture or animation displayed in the starting process of the computer needs to be changed, a new starting picture or animation needs to be added to the BIOS firmware, and the BIOS firmware is updated. On one hand, the updating mode needs to be realized by an operator with professional knowledge of BIOS firmware updating, on the other hand, the updating mode can be realized through a professional tool, and updating failure is easy to occur in the updating process of the BIOS firmware, so that the computer equipment cannot be started. Therefore, the flexibility of the above-described scheme is insufficient.

In order to solve the above technical problems, the related art further provides a method in which a BIOS professional technician sets two different boot images or animations in a BIOS storage space, and selects one of the two boot images or animations as a final boot image or animation according to a client's requirement in a computer device production process. However, the above solutions still have poor flexibility because the number of boot images or animations that can be selected by the client is limited.

The related technology also provides that the startup picture or the animation stored in the BIOS storage space is changed through third-party software. However, this solution needs to be implemented in a specific mode of the operating system, and a third party software may maliciously modify other data in the BIOS storage space, and thus, the security of the above solution is insufficient.

Based on the above problems, embodiments of the present application provide a data writing method.

In the case that the hardware management device is the BIOS, the data writing method provided in the embodiment of the present application can flexibly and efficiently implement addition and/or update of data loaded in the starting process of the electronic device stored in the target storage space of the BIOS through the hardware transmission path between the data transmission device and the target storage space of the BIOS, and the process of writing the first data does not need to depend on a professional technician and a professional tool, and also gets rid of dependence on third-party software, thereby improving flexibility of writing the first data.

In one embodiment, the target state may further include an operating state of the electronic device, and may also include a data output state of a data output device of the electronic device, such as an active data display state of a display device.

For example, the data transmission device may obtain the state of the electronic device and/or the data output device of the electronic device through a communication connection between the data transmission device and a processor or a state register of the electronic device.

For example, the data transmission device may be disposed on a PCH of the electronic device, and in a case that the PCH and the data transmission device are not powered down, when the electronic device is in a non-operating state, other devices or devices may still address the data transmission device.

In the related art, the scheme of updating the boot image or animation of the computer device through the third-party software needs to be executed when the computer device is in the boot state and the display of the computer device is in the activated display state.

That is to say, the data writing method applied to the data transmission device provided in the embodiment of the present application does not strictly limit the target state of the electronic device when the data writing method is executed, and the data writing method can be executed when the electronic device is in any state, so that the flexibility of the data writing method is greatly improved, and the limitation of the data writing operation on the working state of the electronic device is reduced.

Based on the foregoing embodiment, in the data writing method applied to the data transmission apparatus provided in the embodiment of the present application, based on the target address, the first data is written into the first storage unit through the first connection, and the steps A1 to A3 may also be implemented:

In one embodiment, the location and the number of the storage units in the second storage unit may be preset, for example, may be set by a user through an electronic device, a data transmission device or a hardware management device; for example, the number of the storage units in the second storage unit may be plural; for example, the data transfer device may determine a storage unit in which the second data can be written from among the plurality of storage units stored in the second storage unit, and write the second data in the storage unit.

In one embodiment, the first storage unit may be emptied after the data transfer device writes the second data to the second storage unit.

For example, if any one of the on/off, repeated on/off, and repeated off/on commands in the command option 2031 is selected, the selected command may also be sent to the data transmission device through the second connection, and the data transmission device transmits the command to the electronic device, so as to control the electronic device to perform an operation corresponding to the command.

As can be seen from the above, in the data writing method applied to the data transmission apparatus provided in the embodiment of the present application, the first data written into the target storage space of the hardware management apparatus includes data sent by the network device to the data transmission apparatus through the remote connection. Therefore, the diversified modes for writing the first data are provided, the limitation of the distance and/or the region for writing the first data is broken through, and the modes for writing the first data are more flexible and diversified.

Therefore, in the data writing method applied to the data transmission device, the data transmission device can verify the obtained first data, the target address is determined after the verification is passed, and the safety verification of the first data is realized at one end of the data transmission device before the first data is written, so that the probability of writing the risk data into the first storage unit is reduced, and the risk level of the risk data is controlled in advance by verifying the first data in real time after the first data is obtained.

Based on the foregoing embodiment, in the data writing method applied to the data transmission device provided in the embodiment of the present application, determining the target address may also be implemented through steps C1 to C3:

and C1, obtaining the storage state of at least one storage unit in the target storage space.

In one embodiment, if the number of the storage units in the target storage space storing the first state is multiple, the data transmission apparatus may set the storage unit in the first state, which is detected first, as the first storage unit, and may also set each storage unit in the first state as the first storage unit.

And step C3, determining the address of the first storage unit as a target address.

As can be seen from the above, in the data writing method applied to the data transmission device according to the embodiment of the present application, after the storage state of at least one storage unit in the target storage space is obtained, the storage unit in the target storage space, whose storage state is the first state, is determined as the first storage unit, and the address of the first storage unit is determined as the target address.

Wherein the second state comprises a data write complete state.

In one embodiment, the second state may include a state where the data transfer device completes the write operation and data is written correctly; for example, the data transfer apparatus may set the storage state of the first memory cell to the second state under the condition that the storage state of the first memory cell is the first state, and the data transfer apparatus completes the write operation and the data write is correct.

For example, if the electronic device needs to display data in the starting process, the electronic device may address to a target storage space, obtain a storage state of at least one storage unit in the target storage space, and then obtain and display data to be displayed from the storage unit of which the storage state is a second state; for example, the data to be displayed may include first data written by the data transmission device into the first storage unit; for example, if the electronic device determines that the target storage space includes at least two storage units with a second storage state, the electronic device may acquire the data to be displayed from the storage unit with the first detected storage state as the second storage state, and may further determine and display finally displayed data from the at least two data to be displayed by combining the identification information of the data stored in each storage unit with the second storage state.

And D2, setting the storage state of the third storage unit to be a first state through the first connection.

The third storage unit is a storage unit in a preset storage space of the target storage space; the preset storage space comprises a first storage unit and a third storage unit.

In one embodiment, the preset storage space may be a storage space divided from the target storage space and including at least two storage units; for example, the number of the storage units in the preset storage space may be determined or adjusted according to at least one of the data size, the resolution, the type of the data displayed during the starting process of the electronic device, and the updating requirement of the starting-up display data of the user.

For example, the first data may be written to the third storage unit based on the first state when the data transmission device obtains the first data next time.

For example, the operation of setting the first state and the second state by the data transmission device may be triggered by the data transmission device itself, or may be triggered passively based on the control of the user, that is, the data transmission device may execute the operation of setting the state according to the control of the user, so that the user can flexibly select the data displayed during the starting process of the electronic device.

For example, when writing the first data into the first storage unit 301, the data transmission apparatus may write the type or format information of the first data into the fourth storage block 3014, and write the resolution of the first data into the fifth storage block 3015.

Fig. 3B is a schematic structural diagram of a second memory cell 302 according to an embodiment of the disclosure. As shown in fig. 3B, the second storage unit 302 may include a seventh storage block 3021 to a twelfth storage block 3026, and for example, data stored in the seventh storage block 3021 to the twelfth storage block 3026 may be similar to data stored in the first storage block 3011 to the sixth storage block 3016, and are not described here again.

For example, the first storage unit 301 and the second storage unit 302 shown in fig. 3A to 3B may be the first storage unit or the third storage unit provided in the foregoing embodiments. Illustratively, the predetermined storage space may include a first storage unit 301 and a second storage unit 302.

As can be seen from fig. 3A to 3B, the memory blocks in the first memory unit 301 and the second memory unit 302 are clearly divided, and the functions of the data stored in the memory blocks are also clearly defined, which also provides a guarantee for writing the first data in the data transmission device and addressing and acquiring the display data during the startup process of the electronic device.

Fig. 4 is a schematic structural diagram of writing data by the data transmission device according to the embodiment of the present application. In fig. 4, the display device 4011 of the electronic device 401 may present display data, such as a power-on picture or an animation, during a startup process of the electronic device 401, where the display data may be obtained from the storage unit No. one 301 or the storage unit No. two 302 of the target storage space 4012; the data transmission device 4013 may respond to a data write request from the remote apparatus 402, obtain the first data from the remote apparatus 402, and write the first data into the storage unit No. one 301 or the storage unit No. two 302.

For example, the data Transmission device 4013 may obtain first data sent by the remote device 402 through a Transmission Control Protocol (TCP)/IP Protocol, and may further check the first data, and if the first data passes the check, obtain storage statuses of the first storage unit 301 and the second storage unit 302, determine the storage unit whose storage status is the first status as the first storage unit, determine an address of the first storage unit as a target address, and write the first data into the first storage unit through the first connection based on the target address.

Illustratively, the data transmission device 4013 can set the state of the first storage unit to the second state after determining the first storage unit, so that the electronic equipment obtains and displays the first data from the first storage unit based on the second state during the starting process; for example, the data transmission device 4013 may further set the state of the storage unit, except the first storage unit, of the storage unit No. one 301 and the storage unit No. two 302 as the first state, so that the data transmission device 4013 determines a new first storage unit based on the first state when the data writing operation is performed next time, and writes new first data.

For example, in the starting process of the electronic device 401, the hardware management apparatus may detect whether a communication connection is established between the target storage space 4012 and the data transmission apparatus 4013, and if a communication connection is not established between the target storage space 4012 and the data transmission apparatus 4013, establish a first connection between the target storage space 4012 and the data transmission apparatus 4013.

For example, after the first data is written, the first data may be acquired and displayed during the starting process of the electronic device, so as to update the boot image or the animation.

For example, in this embodiment of the application, the data transmission device 4013 may be disposed in the electronic device 401, or may be independent from the electronic device 401.

As can be seen from the above, in the data writing method applied to the data transmission device provided in the embodiment of the present application, after the data transmission device writes the first data, the states of the first storage unit and the third storage unit can be set in real time, so as to provide state support for acquiring and displaying the first data during the starting process of the electronic device and subsequently writing new first data by the data transmission device; in addition, the preset storage space comprises the first storage unit and the third storage unit, so that the storage of at least two display data can be realized through the storage unit in the preset storage space, and the selection range of the display data in the starting process of the electronic equipment is also increased.

Fig. 5 is a schematic flowchart of a process of writing first data into a target storage space by a data transmission apparatus according to an embodiment of the present application, and as shown in fig. 5, the process may include the following steps:

step 501, start.

For example, the hardware management device may establish a first connection between the data transmission device and the target storage space in step 501.

Step 502, the data transmission device waits for an instruction.

For example, the data transmission device may receive an instruction sent by a remote device through the second connection, and may also receive an instruction sent by a device or equipment with which an electrical connection is established.

Step 503, determine whether it is a display data write command.

For example, the data transmission device may determine whether the received command is a display data writing command, if not, continue to perform step 502, and if so, perform step 504; for example, the display data may include picture or animation data loaded during a power-on start-up process of the electronic device.

Step 504, the data transmission device applies for a buffer space.

For example, the data transmission device may determine the size of the buffer space based on the data type and/or the data size contained in the received instruction; for example, the data transmission device may apply for a buffer space from its internal memory space.

Step 505, the data transmission device receives the first data and buffers the first data in the buffer space.

Illustratively, the data transmission device may receive the first data based on the TCP/IP protocol through the second connection and buffer the first data into the buffer space.

Step 506, determining whether the first data is received completely.

For example, the data transmission apparatus may determine whether the first data is completely received, if not, continue to perform step 505, and if so, perform step 507.

Step 507, the data transmission device searches the first storage unit in the target storage space.

For example, the data transmission device may determine a storage unit that does not store valid data in the target storage space as the first storage unit, and may also determine any found storage unit that can store the first data as the first storage unit.

For example, the data transmission apparatus may traverse a Serial Peripheral Interface (SPI) bus, and search index information stored in the first storage block 3011 and the seventh storage block 3021 in fig. 3A to 3B in the target storage space, so as to implement the search for the first storage unit.

Step 508, determine whether the first storage unit is found.

For example, the data transmission device may determine whether the first storage unit is found, and if not, continue to execute step 507; if so, go to step 509.

In step 509, it is determined whether the storage state of the first storage unit is the first state.

For example, the data transmission apparatus may determine whether the memory cell of the first memory cell is in the first state, if so, perform steps 510 to 514, and if not, perform step 515.

Step 510, write the first data to the first memory cell through the first connection.

For example, the data transfer device may write the first data to the first storage unit through the first connection.

Step 511, determining whether the first data is written.

For example, the data transmission apparatus may determine whether the first data is written, if not, continue to perform step 510, and if so, may perform step 512.

Step 512, setting a first state and a second state.

For example, the data transmission device may set the storage state of the first storage unit to the second state and set the storage state of the third storage unit to the first state.

And 513, sending a reply message to the remote device to prompt that the first data writing is completed.

For example, the data transfer device may send a reply message back to the remote device to prompt completion of the first number write.

And step 514, ending.

For example, the data transfer device may continue to perform step 502 to initiate a new data write-once process.

Step 515 determines whether the storage state of the third storage unit is the first state.

For example, the data transmission apparatus may determine whether the storage state of the third storage unit is the first state, if not, step 516 may be executed, and if yes, step 517 may be executed.

Step 516, sending a reply message to the remote device to prompt that the first data cannot be written.

For example, the data transmission apparatus may send a reply message to the remote device to prompt that the remote device cannot currently write the first data; illustratively, the reply message may further include a reason for the failure of the first data write.

Step 517, writing the first data into the third storage unit through the first connection.

For example, the data transmission device may write the first data to the third storage unit through the first connection; for example, steps 511 to 514 may be performed after step 517 to write the first data to the third storage unit.

For example, the data transmission device may still write the first data into the first storage space or the third storage space when the electronic device is in a power-off state, a sleep state, a hibernation state, or the like.

Therefore, under the control of the remote equipment, the data transmission device can write the first data into the first storage unit or the third storage unit safely and stably through the first connection between the data transmission device and the target storage space without the cooperation of third-party software and the professional knowledge and tools of professional technicians, so that the flexible writing and updating of the display data in the target storage space and in the starting process of the electronic equipment are greatly improved.

The target storage space comprises a storage space used by the hardware management device for storing data displayed in the starting process.

For example, if the electronic device detects that the first connection is already established, the operation of establishing the first connection may not be performed any more.

Step 602, during the start-up process, a target address is determined.

The target address comprises an address of a first storage unit in the target storage space; the first storage unit includes a storage unit in the target storage space into which the first data is written by the data transfer device through the first connection.

Step 603, in the starting process, based on the target address, the first data is obtained from the first storage unit and displayed.

As can be seen from the above, in the data writing method applied to the electronic device provided in the embodiment of the present application, during the starting process of the electronic device, the first storage unit can be determined based on the storage state of at least one storage unit in the target storage space, and the address of the first storage unit is determined as the target address.

Therefore, the storage state can accurately reflect the data storage state of the storage unit in the target storage space, and the stability of the electronic equipment for acquiring the first data can be improved based on the first storage unit and the target address determined by the storage state, so that the smooth operation of the starting process is ensured.
