Description

Technical Field

[0001] The present invention relates to the field of computer technology, and more specifically, to a method and system for a network interface to perform PXE boot startup by specifying an address at the UEFI stage. Background Art

[0002] In modern computer network management, the PXE (Preboot eXecution Environment) startup technology plays a crucial role. This technology allows a computer to load an operating system and applications from a remote server over the network without relying on a local storage device. PXE startup not only simplifies the system deployment process but also improves the flexibility and management efficiency of the IT infrastructure.

[0003] Currently, after a computer selects PXE (Pre-boot Execution Environment) boot, each network interface in the standard UEFI mode will execute PXE once, resulting in an increase in the computer's boot time. Moreover, if the on-board network interface chip models are the same, the information displayed in the Boot Menu interface of the UEFI BIOS is the same, and it is difficult for users to distinguish the network interface corresponding to each startup option. There is a need for a method and system for a network interface to perform PXE boot startup by specifying an address at the UEFI stage to solve the above problems in this scenario. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to provide a method for a network interface to perform PXE boot startup by specifying an address at the UEFI stage in view of the above-mentioned defects of the prior art, and also provide a system for a network interface to perform PXE boot startup by specifying an address at the UEFI stage.

[0005] The technical solution adopted by the present invention to solve its technical problems is as follows:

[0006] Construct a method for a network interface with a specified MAC address at the UEFI stage to perform PXE boot startup, wherein the method includes the steps of:

[0007] Step 1: After powering on, determine whether an instruction to select to enter the BIOS Setup to specify MAC address PXE boot is received. If so, restart and proceed to the next step; otherwise, continue with UEFI startup.

[0013] Step 7: Obtain the MAC address of the network card device. Determine whether the MAC address of the network card device is the same as the specified MAC address. If so, proceed to the next step; otherwise, jump to Step 9.

[0014] Step 8: Load the PXE driver to boot and jump to Step 10.

[0015] Step 9: Determine whether the next boot device is successfully obtained. If so, jump to Step 3; otherwise, jump to Step 10.

[0016] Step 10: Continue with UEFI boot.

[0024] Obtain the PciHandle of the current device according to the DevicePath;

[0025] Obtain the PciIo pointer according to the PciHandle and read the PciClass;

Among them, the system includes a BISO module, and the BISO module is used to execute the PXE boot method for the network port that specifies the MAC address in the UEFI stage as described in claim 1.

At the same time, the MAC address of the network card is added before the network boot option in the BootMenu interface of the UEFI BIOS to distinguish the network card corresponding to each network boot option, which can well solve the problem that it is difficult for users to distinguish the network port corresponding to each boot option.
