[0048] The output terminal of the Micro SD card is connected to the input terminal of the baseboard management controller;

[0049] The Micro SD card is used to store the firmware version set information of the basic input / output system.

[0050] Specifically, the Micro SD card is a TF (Trans-flash Card), which is an extremely small flash memory card.

[0051] In a preferred embodiment, the system further includes a complex programmable logic device.

[0052] The output terminal of the VR chip is connected to the input terminal of the complex programmable logic device, and the output terminal of the complex programmable logic device is connected to the second input terminal of the basic input / output system.

[0054] In a preferred embodiment, the complex programmable logic device is also used to control the VR chip to power off or power on the basic input / output system chip.

[0055] In a preferred embodiment, the baseboard management controller is further configured to acquire the basic input / output system firmware version set information in the Micro SD card and display the basic input / output system firmware version set information on a web page interface.

[0056] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0057] The technical solution provided by this invention includes a baseboard management controller, a basic input / output system (PIS), and a VR chip. The output terminal of the baseboard management controller is connected to the first input terminal of the PIS, and the output terminal of the PIS is connected to the input terminal of the VR chip. This invention's technical solution can automatically and seamlessly switch BIOS firmware versions without affecting customer business operations, greatly meeting customer needs, improving operational efficiency, and is applicable to various types of servers.

[0058] With this invention, customers can select their desired customized BIOS firmware version through a web interface, click save, and automatically and seamlessly switch to the customized BIOS firmware version without affecting their business operations.

[0059] Example 2

[0060] This invention provides a firmware version switching method, such as... Figure 2 As shown, the method includes:

[0061] Step S1: Set the corresponding basic input / output system firmware version set according to different business scenarios, and upload the basic input / output system firmware version set to the Micro SD card.

[0062] Specifically, based on different business scenarios of customers, we allow customers to put forward their different requirements and make different customized basic input / output system BIOS firmware versions, such as BIOS firmware 1, BIOS firmware 2... BIOS firmware n.

[0063] At the same time, all BIOS firmware versions, i.e., the corresponding basic input / output system firmware version sets set according to different business scenarios, are uploaded to the TF card (Trans-flash Card).

[0064] Step S2: Obtain the basic input / output system firmware version set information in the Micro SD card.

[0065] Specifically, the Baseboard Management Controller (BMC) accesses the TF card, obtains the version information of all BIOS firmware in the TF card through I2C communication, and displays the version information of all BIOS firmware on the web interface.

[0066] Step S3: Confirm the customized basic input / output system firmware version from the basic input / output system firmware version set.

[0067] Specifically, the customer confirms the customized basic input / output system firmware version from the set of basic input / output system firmware versions. That is, the customer selects different customized basic input / output system firmware versions according to their own needs and clicks save.

[0068] Step S4: The customized basic input / output system firmware version is mounted from the Micro SD card to the basic input / output system flash memory via the network LAN communication protocol.

[0069] Specifically, after the Baseboard Management Controller (BMC) obtains the customized Basic Input / Output System (BIOS) firmware version selected by the customer, it loads the customized BIOS firmware version selected by the customer from the TF card to the BIOS flash memory via the LAN over USB protocol.

[0070] Step S5: Run the mounted customized basic input / output system firmware version and refresh the customized basic input / output system firmware version.

[0071] Specifically, mounting space is reserved in the BIOS flash memory of the Basic Input / Output System (BIOS) and a customized BIOS firmware version is run. While running the customized BIOS firmware version, the customized BIOS firmware version is refreshed.

[0072] Step S6: Power the basic input / output system chip separately through the VR chip, restart the server system, and switch the customized basic input / output system firmware version.

[0073] Specifically, existing technology involves the motherboard supplying power to the BIOS chip. Here, the VR chip is used to power on or off the BIOS chip independently, restarting the server system and switching the customized BIOS firmware version. This can be done automatically and seamlessly without affecting customer business operations, greatly meeting customer needs, improving operational efficiency, and is applicable to various types of servers.

[0074] Step S6 includes:

[0075] In step S61, the complex programmable logic device monitors the progress of refreshing the customized basic input / output system firmware version mounted in the flash memory of the basic input / output system. When the refresh of the customized basic input / output system firmware version is completed, the complex programmable logic device controls the VR chip to power off and then power on the basic input / output system chip.

[0076] Specifically, the Complex Programmable Logic Device (CPLD) monitors the progress of refreshing the customized firmware version of the Basic Input / Output System (PIOS) flash memory. Once the refresh is complete, the CPLD controls the VR chip to individually power off and then power on the PIOS chip.

[0077] Step S7: End the mounting of the customized basic input / output system firmware version in the basic input / output system flash memory.

[0078] Specifically, after the customized basic input / output system firmware version is switched and the server system is restarted, the customized basic input / output system firmware version will be demounted from the basic input / output system flash memory after the basic input / output system takes effect.

[0079] Specifically, this invention proposes a method for automatically and seamlessly switching the Basic Input / Output System (BIOS) firmware version via the Baseboard Management Controller (BMC). The core design idea of ​​this method is based on traditional customer needs. When a customer requires different customized firmware versions, they flash the corresponding customized firmware, and then restart the system to make the new BIOS firmware version effective. However, this traditional method can no longer meet the customer's need to change the BIOS firmware version without affecting business operations. This invention improves upon the flashing of different customized firmware versions to form a method for automatically and seamlessly switching the BIOS firmware version. Through this firmware version switching method, when a customer requires different customized BIOS firmware versions, the BIOS firmware version can be automatically and seamlessly switched without affecting business operations.

[0080] The firmware version switching method provided in this embodiment of the invention can be improved and optimized in several ways without departing from the technical solution of this invention, and these improvements and optimizations should also be considered within the scope of protection of this invention.

[0081] Meanwhile, the firmware version switching schemes used in other devices that require switching between different firmware versions are also within the scope of protection of this invention.

[0082] The beneficial effects of the technical solution provided by the embodiments of the present invention are as follows:

[0083] Compared with existing technologies, the technical solution provided by the embodiments of the present invention has strong replicability and scalability. It can automatically and seamlessly complete the BIOS firmware version switch without affecting the operation of customer business, which greatly meets the needs of customers, improves operation and maintenance efficiency, and can be applied to various types of servers.

[0087] In this embodiment, the acquisition module is used to acquire the basic input / output system firmware version set information in the Micro SD card;

[0088] The selection module is used to identify a customized basic input / output system firmware version from the set of basic input / output system firmware versions.
