Embodiment 1

[0031] A method for implementing BIOS configuration modification at the OS level, such as figure 1 shown, including the following steps:

[0032] S1: Select a suitable boot device to start the system, open the application tool at the application layer, obtain the driver access interface, the interface is the API interface opened by the driver program to the application layer, and issue a read or write BIOS configuration command;

[0033] S2: The driver layer converts the virtual address and the physical address, and triggers the SMI soft interrupt;

[0034] S3: The BIOS layer enters the SMM mode, and the BIOS menu configuration is modified.

[0035] like figure 2 As shown, the step S1 includes:

[0036] S11: Power on the main board and start it up;

[0037] S12: check the status of GPIO;

[0038] S13: Select a boot device according to the state of the GPIO, where a disk for booting an operating system is installed on the boot device.

[0039] The step S13 includes: the ...

Abstract

The invention discloses a method for realizing BIOS (Basic Input / Output System) configuration modification at an OS (Operating System) level, which belongs to the technical field of computers and comprises the following steps of: selecting proper starting equipment to start a system, opening an application tool on an application layer, acquiring a drive access interface and sending a BIOS configuration command; the driving layer performs conversion between a virtual address and a physical address, and triggers SMI soft interrupt; the BIOS layer enters an SMM mode, and BIOS menu configuration is modified; an application tool is adopted to act on an OS, configuration of a BIOS can be achieved, meanwhile, a drive interface is called through a webpage background, deeper customization can be achieved, dependence on an HII frame can be avoided, the system can support all display libraries, and an interface which a user wants to display can be customized according to the requirements of the user.

Description

technical field [0001] The invention relates to the technical field of computers, in particular to a method for implementing BIOS configuration modification at OS level. Background technique [0002] At present, mainstream BIOS (Basic Input Output System) manufacturers provide configuration modification methods by providing UI interfaces in the UEFI (Unified Extensible Firmware Interface) environment, and manually adjusting configuration parameters by users. Although the operation method is simple, this method There are still disadvantages: configuration modification cannot be realized; UI configuration interface modification is difficult and portability is low. [0003] SMM is a standard architectural feature common to all Intel processors. This mode provides a transparent mechanism for the OS to implement platform-specific functions such as power management or system security. When the external SMI is activated or receives an SMI from the APIC (Advanced Programming Inter...
