Embodiment Construction

[0023] The present invention will be further described below with reference to the drawings and embodiments.

[0024] EFI-based cross-platform and cross-processor device embodiment

[0025] figure 1 An embodiment of an EFI-based cross-platform and cross-processor device is shown. See figure 1 The device of this embodiment is essentially an improvement over traditional EFI. In addition to the core units that traditional EFI already has, such as the device configuration service unit, console service unit, file interface unit, and startup service unit, the special features of this embodiment The point is that the processor virtual unit and operating system virtual unit are added. The above-mentioned traditional core units are mainly for initializing computer hardware and providing some runtime services, such as graphical interface support that is more powerful than BIOS, hard disk partitioning, file interface services, etc.

[0026] The processor virtual unit detects the processor pl...

Abstract

The invention discloses a cross-platform and cross-processor method based on an extensible firmware interface and a device, which solves the match problem of EFI on an operation system and a processor. The technical scheme is as follows: the device comprises a processor virtual unit except traditional units of an equipment configured service unit, a control board service unit, a document interfaceunit, a starting service unit and the like; the processor virtual unit is used for checking the processor of the computer and loading a corresponding EFI driving program according to the processor; and an operation system virtual unit is used for checking the current operation system platform of the computer, and loading a corresponding EFI function library according to the platform of the current operation system.

Description

Technical field [0001] The present invention relates to a cross-operating system platform and cross-processor virtual realization method and device, in particular to a cross-platform and cross-processor virtual realization method and device implemented by using Extensible Firmware Interface (EFI) . Background technique [0002] Traditional BIOS (Basic Input / Output System) is a bridge between operating system and hardware system. BIOS is a converter between hardware and software programs. It is responsible for solving the immediate needs of the hardware and specifically implementing the operating requirements of the software on the hardware. It is responsible for the initialization work before the execution of the operating system, including checking the system equipment and connecting various hardware and operating systems in the computer. As software written in low-level assembly language, BIOS has existed for a long time in the form of 16-bit assembly code, register parameter...
