Embodiment Construction

[0023] Such as figure 1 As shown, the method steps of the embodiment of the present invention are as follows:

[0024] Step 1: Develop the wireless network card driver, see figure 2 .

[0025] S1: Transplant the wireless network card driver: modify the wireless network card driver code, delete the part of the wireless network driver code in the operating system kernel that is related to the operating system kernel;

[0026] S2: Add the detection code of the wireless network card: add the function of detecting the wireless network card of various interfaces in the code, and detect whether there is a wireless network card. The priority order of detecting various interface types of wireless network cards is: PCI-E interface type, SPI interface type, SDIO interface type, and USB interface type. For details, see image 3 . After the device is detected, the device is initialized, and the operation of the network card is exited if the device is not detected. The code should be ...

Abstract

The invention discloses a method of realizing a wireless card driver in a UEFI (unified extensible firmware interface) layer. The method comprises the steps of transplanting and modifying the wireless card driver, adding the codes of wireless card driver detection and initiation and realizing a network protocol interface; rewriting, recompiling and programming the codes to a development board; powering on the system, operating the UEFI firmwire, initializing the hardware and realizing all the services defined by all the needed UEFI standards for an upper interface. A UEFI startup manager loads UEFIShell, the UEFIShell loads the wireless card driver and a transmission control protocol / internet protocol (TCP / IP) stack module, a wireless network communication environment is established, and the operating system is remotely booted through the wireless network. The method can realizing the detection, the initiation and the data read-write of the wireless network equipment in an environment without the operating system and the reliance of the wireless network equipment on the operating system is removed.

Description

technical field [0001] The invention relates to the technical field of wireless networks, in particular to a method for realizing the driver of a wireless network card at the UEFI layer. Background technique [0002] At present, the traditional BIOS (Basic Input / Output System) solidifies the basic driver, while other drivers need to be loaded by the operating system kernel. Among them, the wireless network card driver is particularly obvious, and it has a strong dependence on the operating system. The wireless network card driver is integrated in the kernel of the operating system, and the wireless network device can be identified and data read and written after the operating system is started. [0003] UEFI (Unified Extensible Firmware Interface, Unified Extensible Firmware Interface) is the next-generation PC BIOS architecture proposed by Intel. It provides BIOS standards and driver development interfaces for independent BIOS and hardware manufacturers, and also builds a ...
