Embodiment 1

[0044]Example 1:figure 1 A flow diagram of a startup method of a UEFI is provided for the present invention, including the steps of:

[0045]S1, initialization of CPU, memory, motherboard, and chipset;

[0046]S2, by enumerating the device sort number of all PCI and PCIe devices in the computer;

[0047]S3, get the drive path of the startup device of the device classification number is a specific classification number;

[0048]S4, load the starter driver according to the drive path;

[0049]S5, start the operating system.

[0050]The application environment of the present invention may be a domestic platform (such as a dragon core), or the import platform (Intel X86 platform), the platform frame can be and is not limited to the X86 platform, the ARM platform.

[0051]Step Step The role of the PXE (Pre-Boot Execution Environment) phase is the platform for establishing the driver running.

[0052]Step S2-S4 steps at the BDS (Boot Device Select, startup device selection) started by UEFI.

[0053]Device Category ...

Embodiment 2

[0056]Example 2: The above method, set a specific classification number, including:

[0057]Initialize CPU, memory, motherboard and chipset

[0058]Load the graphics driver, keyboard drive;

[0059]Enter the UEFI setting interface in response to a specific input to the keyboard;

[0060]Determine a specific classification number based on the settings of the user in the setting interface.

[0061]In practical applications, the graphics card driver and keyboard drive the user set the driver necessary for the UEFI, and the mouse driver can be loaded, and the user can set up the UEFI. The contents of the set may include only the quick start mode of the driver of the device that only loads only the user selected, or the normal start mode of the driver of all devices that load enumerations.

[0062]The user sets the device type to load the driven device, or select the device name to load the drive in all devices previously enumerated, and form a list of devices to load for loading the driver. At S3 steps, ...

Embodiment 3

[0064]Example 3: The above method, the specific classification number is one of the following types:

[0065]Hard disk devices, network devices, RAID devices, USB devices.

[0066]Based on the same inventory, the UEFI and the computer are also provided in the embodiment of the present invention, and since the principle of the UEFI and the computer solve the problem are similar to the above method, the implementation of the UEFI and the computer can see the implementation of the method and repeat. .

Abstract

The invention relates to the field of computers, in particular to a UEFI (Unified Extensible Firmware Interface) starting method, which comprises the following steps: 1, initializing a CPU (Central Processing Unit), a memory, a mainboard and a chipset; 2, determining equipment classification numbers of all PCI and PCIe equipment in the computer through enumeration; 3, acquiring a driving path of the starting equipment of which the equipment classification number is a specific classification number; 4, loading a driving program of the starting equipment according to the driving path; 5, starting an operating system. According to the method provided by the invention, in the starting process of the UEFI, only the equipment of the category selected by the user is loaded, so that the starting time of some equipment which is not needed by the user can be reduced, and the starting speed of the UEFI is improved.

Description

Technical field[0001]The present disclosure relates to the field of computer, and more particularly to the startup method, UEFI, and computer of the UEFI.Background technique[0002]UEFI (Unified Extensible FIRMWARE INTERFACE, Unified Extensible Firmware Interface) is a personal computer system specification that defines the software interface between the operating system and the system firmware, which is an alternative to the Bios (BasicInput / Output System, Basic Input Output System). Program. UEFI is responsible for Post (Power-Onself-Test, power-on self-test), contact operating system and providing an interface to the operating system and hardware.[0003]The advantage of UEFI is:[0004]1, BIOS only supports assembly development language programming, UEFI supports C language programming;[0005]2, BIOS only supports reading startup code from the hard disk, UEFI support file system, can directly read files in the FAT file system, if the file is the application, can be executed directly...
