Abstract

A method for acquiring a network adapter MAC address is applied to network equipment. The method comprises the following steps: reading bus address information of a network adapter of the network equipment during booting; judging whether the bus address of the network adapter is 0x0 or 0xFF; if the bus address of the network adapter is not 0x0 or 0xFF, reading base address information of the network adapter; reading a MAC address of the network adapter based on a designated offset position in a mapping space corresponding to the base address of the network adapter; saving the MAC address of the network adapter as a Setup variable to be displayed on a BIOS human-machine interface. By using the method for acquiring the network adapter MAC address, the MAC address of the network adapter of the network equipment can be automatically detected during the booting, and the MAC address can be displayed on the BIOS human-machine interface for being conveniently checked by the user, accordingly increasing the user experience.

Description

technical field

[0001] The invention relates to a method for acquiring the hardware address of a network card. Background technique

[0002] The MAC (Media Access Control) address is the hardware address, which is a dedicated address used to define the location of network devices; the network card is a network component working at the link layer, and is the interface connecting the computer and the transmission medium in the network; when performing network transmission At this time, the unique identifier for identifying a network device is the MAC address of the network card of the device. Only through the MAC address of the network card can the network identify the network device that sends the data and the network device that receives the data. At present, to obtain the MAC address of the network card generally needs to enter the operating system of the network device, and can only be obtained through the commands built in the system or other software, which is very incon...
