Abstract

The invention discloses a method for preventing a user from illegally modifying an operating system (OS). The method comprises the steps as follows: (1) after a basic input / output system (BIOS) is started, a central processing unit (CPU) sends out an instruction of requesting to supply electricity to a universal serial bus (USB) connector connected with an OS FW to a BMC; (2) the BMC receives the instruction and supplies electricity to the USB connector connected with the OS FW; (3) the CPU reads the OS FW to decompress in a memory, and starts the decompressed OS, and meanwhile, the CPU sends out an instruction of stopping supplying electricity to the USB connector connected with the OS FW to the BMC; and (4) the BMC receives the instruction and stops supplying electricity to the USB connector. According to the method, through internal installation of the OS in the BIOS of a server, the user can only use the built-in OS and cannot use other OS, so that the user is prevented from illegally modifying the OS; and an unauthorized operation is effectively prevented from accessing and modifying the OS FW.

Description

technical field

[0001] The invention belongs to the technical field of server products, and more specifically relates to a method for preventing users from illegally modifying an OS. Background technique

[0002] The way of the prior art is that BIOS (Basic Input Output System, basic input and output system) does not have built-in OS (Operating System, operating system), BIOS FW (Firmware, firmware) is stored in Flash, and OS FW is stored in an external storage device (such as hard disk, U disk, etc.), after the BIOS starts, it scans the external storage device, enumerates all installed OS for the user to choose, and then starts the OS selected by the user or starts the default OS after waiting for a timeout.

[0003] The disadvantage of the prior art is that the OS is stored in an external storage device, and the user can install and modify it arbitrarily. Existing technologies cannot meet the needs of cloud server manufacturers, etc., who hope to deploy a safe and reliabl...
