[0038] The embodiments of the present invention provide a method for adding a BIOS recovery function applied to a smart network card, a network card for adding a BIOS recovery function applied to a smart network card, a server for adding a BIOS recovery function applied to a smart network card, a system for adding a BIOS recovery function applied to a smart network card, and a computer-readable storage medium for adding a BIOS recovery function applied to a smart network card. As for the implementation of the method for adding a BIOS recovery function applied to a smart network card, the embodiments of the present invention will describe an exemplary implementation scenario of the method for adding a BIOS recovery function applied to a smart network card.

[0039] like Figure 1 As shown, a flow chart of a method for adding a BIOS recovery function applied to a smart network card in an embodiment of the present invention is shown. It is worth noting that the method for adding a BIOS recovery function applied to a smart network card in this embodiment is applied to the network card end. The network card end is connected to the server end in communication, and the network card end includes a BIOS switch.

[0040] Specifically, in this embodiment applied to the network card side, the method for adding the BIOS recovery function applied to the smart network card mainly includes the following steps:

[0041] Step S11: the server side is powered on in response to the connection with the server side.

[0042] In one embodiment of the present invention, the connection method between the network card end and the server end includes: a USB interface, a USB interface that can support TYPE-C to USB, a PCIe bus, etc.

[0043] Step S12: receiving a BIOS file corresponding to the network card from the server, wherein the BIOS file is obtained by querying a plurality of pre-stored BIOS files by the server in response to the activation of the BIOS switch.

[0044] In one embodiment of the present invention, the server stores a plurality of BIOS files, wherein the plurality of BIOS files have different BIOS version file names, and a character string search is performed according to the BIOS version file name required for BIOS recovery by the network card, thereby confirming the BIOS file required by the network card. The BIOS file includes an erasable BIOS data memory and a readable BIOS program memory.

[0045] Step S13: after executing the power-on operation in response to the power-on instruction issued by the server, executing a BIOS recovery action based on the BIOS file.

[0046] In one embodiment of the present invention, it is worth noting that the power-on operation includes two steps: power off and power on again. After the network card is inserted into the server slot, the network card is powered by the server. Manually plugging and unplugging the network card to power off and power on again may cause the internal circuit of the network card to be broken. Therefore, the power-off and power-on operation described here is that the server controls the power supply of the network card through the control module placed on the server, and the network card is powered off through the interface connected to the network card, and then powered on again.

[0047] like Figure 2 As shown, a circuit structure diagram of a BIOS switch in an embodiment of the present invention is shown. A BIOS switch is included at the network card end. The BIOS switch includes: a first pin 22 and a second pin 23. The first pin 22 is respectively connected to a BIOS function recovery signal terminal 221 and a power supply signal terminal 222 at the network card end; the second pin 23 is connected to a ground signal terminal 231.

[0048] In one embodiment of the present invention, the BIOS switch further includes a pin connector 21; the pin connector 21 includes a jumper cap, a dip switch, a self-locking switch, an open-circuit resistor, etc. For example, the jumper cap is composed of a plastic shell and a metal pin, and the jumper cap can be used to connect and disconnect multiple circuit nodes. The jumper cap connects or disconnects the first pin 22 and the second pin 23 to control the switch of the BIOS recovery function of the network card.

[0049] In one embodiment of the present invention, the state in which the pin connector 21 connects the first pin 22 and the second pin 23 and the state in which the first pin 22 and the second pin 23 are not connected correspond to one and the other of the BIOS switch being in the on state and the off state, respectively.

[0050] Specifically, there are two solutions: Solution 1) The state in which the pin connector 21 connects the first pin 22 and the second pin 23 corresponds to the BIOS switch being in the on state, and the state in which the pin connector 21 does not connect the first pin 22 and the second pin 23 corresponds to the BIOS switch being in the off state. Solution 2)

[0051] In the following, only scheme 1) is used as an example for explanation. Those skilled in the art can undoubtedly infer the implementation process of the above scheme 2) based on the implementation process of scheme 1).

[0052] In some embodiments of the present invention, when the first pin 22 and the second pin 23 are connected, at this time, since the power supply signal terminal 222 is connected to the ground signal terminal 231, the BIOS function recovery signal terminal 221 connected to the power supply is in a low level mode, and the BIOS recovery function is in a closed state. On the contrary, when the jumper cap is removed to disconnect the first pin 22 and the second pin 23, the BIOS function recovery signal terminal 221 is only connected to the power supply signal terminal 222, and the power supply signal terminal 222 is in a high level mode, and the BIOS recovery function is in an open state. If the jumper cap is connected to the first pin 22 and the second pin 23 again, the BIOS function recovery signal terminal 221 is reset, and the BIOS function recovery signal terminal 221 returns to the low level mode, and the BIOS recovery function is closed. It is worth noting that the above-mentioned power supply signal source can be a conventional power supply voltage such as 3.3V or 5V.

[0053] like Figure 3 As shown, a flow chart of a method for adding a BIOS recovery function applied to a smart network card in an embodiment of the present invention is shown. It is worth noting that, unlike the above-mentioned embodiment, the method for adding a BIOS recovery function applied to a smart network card in this embodiment is applied to a server side. The server side is communicatively connected to a network card side, and the network card side includes a BIOS switch.

[0054] Specifically, in this embodiment applied to the server, the method for adding a BIOS recovery function applied to the smart network card mainly includes the following steps:

[0055] Step S21: powering on the network card terminal in response to the connection with the network card terminal.

[0056] In some embodiments of the present invention, the connection method between the server and the network card end includes: the server end is connected to the UART pin of the network card end through a serial port. The UART pin is a physical interface for serial communication, and the UART pin converts the data to be transmitted between serial communication and parallel communication. The UART pin includes: a 3.3V power supply pin, a ground pin, a ground pin, and a data transmission pin.

[0057] Step S22: In response to the turning-on action of the BIOS switch, a query is performed in a plurality of pre-stored BIOS files to obtain a BIOS file corresponding to the network card end, and the BIOS file is sent to the network card end.

[0058] In some embodiments of the present invention, the server is configured with a query function for querying the file name of the BIOS version corresponding to the network card. The specific query process includes: the server detects the model of the network card and the corresponding BIOS file version number through the interface, and then searches for a BIOS file that matches the BIOS version file name on the server through the query function of the server based on the BIOS version file name of the network card through string matching. The BIOS file is a firmware file for the network card to perform BIOS recovery.

[0059] Step S23: issuing a power-on command to power on the network card end again, so as to display and monitor the BIOS recovery process of the network card end after the network card end executes the BIOS recovery action based on the BIOS file.

[0060] In some embodiments of the present invention, before the server starts to send a power-on command to the network card, it is necessary to confirm whether BOOTBLOCK is in a lossless state. It is worth noting that BOOTBLOCK is a specific area located in the BIOS instructions, which is mainly used to guide the minimum instruction set in the BIOS recovery process. BOOTBLOCK cannot be erased during the BIOS recovery process. BOOTBLOCK bypasses the normal startup and directly enters the BIOS state through a set of minimum instruction sets. Confirming that BOOTBLOCK is in a lossless state can ensure that the BIOS recovery process of the network card can run normally.

[0061] In some embodiments of the present invention, after the network card is powered on again, the server side will judge the level of the BIOS function recovery signal end of the network card side. If the BIOS function recovery signal end is at a high level, the server side will perform BIOS recovery on the network card side. If the BIOS function recovery signal end is at a low level, the server side will not perform BIOS recovery on the network card side, and the network card will be powered on and started normally. It is worth noting that the high level and low level of the BIOS function recovery signal end described here corresponding to the turning on or off of the BIOS recovery function are only used to explain the role of the present invention rather than to limit the role. The corresponding relationship between the level state of the BIOS function recovery signal end of the present invention and the turning on or off of the BIOS recovery function corresponding to its different states is not limited.

[0062] In some embodiments of the present invention, the method of displaying and monitoring the BIOS recovery process of the network card side includes: the server side displays the BIOS recovery process in the PUTTY tool through the serial port and monitors it. The server side is configured with the PuTTY tool to display the progress status of the BIOS recovery of the network card side to improve the user experience.

[0063] The above describes the embodiment of the method for adding a BIOS recovery function to a smart network card provided by the present invention, which is applied to the network card end and the server end. Figure 4 and Figure 5 The network card and server to which the method for adding the BIOS recovery function applied to the smart network card are applied are described in detail.

[0064] like Figure 4 As shown, a schematic diagram of the structure of a network card with a BIOS recovery function added to a smart network card in an embodiment of the present invention is shown. In this embodiment, a network card 30 with a BIOS recovery function added to a smart network card includes:

[0065] The BIOS switch module 41 is used to enable or disable the BIOS recovery function.

[0066] The communication module 42 is used to establish a communication connection with the server and receive a BIOS file corresponding to the network card from the server. The BIOS file is obtained by querying a plurality of pre-stored BIOS files by the server in response to the activation action of the BIOS switch.

[0067] The BIOS recovery module 43 is used to perform a BIOS recovery action based on the BIOS file after performing a power-on operation in response to a power-on instruction issued by the server.

[0068] In some examples, the BIOS switch module 41 includes a first pin and a second pin, the first pin is connected to the BIOS function recovery signal terminal and the power supply signal terminal of the network card end respectively; the second pin is connected to the ground signal terminal, and the BIOS switch further includes a pin connector. The state in which the pin connector connects the first pin and the second pin, and the state in which the first pin and the second pin are not connected, respectively correspond to one of the BIOS switch being in an on state and the other of the off state. The communication module 42 is connected to the server end through the UART pin of the network card end.

[0069] It should be noted that: the above-mentioned embodiment provides a BIOS recovery function for adding a network card to the smart network card when performing BIOS recovery, and only uses the division of the above-mentioned program modules as an example. In actual applications, the above-mentioned processing can be assigned to different program modules as needed, that is, the internal structure of the device is divided into different program modules to complete all or part of the processing described above. In addition, the BIOS recovery function for adding a network card to the smart network card provided in the above-mentioned embodiment and the BIOS recovery function adding method embodiment applied to the smart network card belong to the same concept, and the specific implementation process is detailed in the method embodiment, which will not be repeated here.

[0070] like Figure 5 As shown, a schematic diagram of the structure of a server for adding a BIOS recovery function to a smart network card in an embodiment of the present invention is shown. In this embodiment, a server 40 for adding a BIOS recovery function to a smart network card includes:

[0071] Communication module 51: used for establishing a communication connection with the network card, and sending the BIOS file corresponding to the server to the network card.

[0072] The query module 52 is configured to query a plurality of pre-stored BIOS files to obtain a BIOS file corresponding to the network card in response to the activation of the BIOS switch.

[0073] The power supply module 53 is used to power on the network card terminal in response to the connection with the network card terminal.

[0074] The monitoring module 54 is used to issue a power-on command to power on the network card, so as to display and monitor the BIOS recovery process of the network card after the network card executes the BIOS recovery action based on the BIOS file.

[0075] In some examples, the communication module 51 is connected to the UART pin of the network card end through a serial port. The process in which the query module 52 queries a plurality of pre-stored BIOS files to obtain a BIOS file corresponding to the network card end includes: searching for a BIOS file that matches the BIOS version file name on the server end based on the BIOS version file name of the network card end through the query function of the server end. The monitoring module 54 displays and monitors the BIOS recovery process of the network card end in a manner that: the server end displays and monitors the BIOS recovery process in PUTTY through the serial port.

[0076] It should be noted that: the BIOS recovery function adding server applied to the server provided in the above embodiment only uses the division of the above program modules as an example when performing BIOS recovery for the network card. In actual applications, the above processing can be assigned to different program modules as needed, that is, the internal structure of the device can be divided into different program modules to complete all or part of the processing described above.
