A method for starting an operating system based on a network

Abstract

The invention discloses a method for starting an operating system based on a network, which comprises the following steps in sequence: S1, a client obtains an IP address for a computer that needs to be started; S2, downloads a kernel file of a first operating system from a first server; S3 1. The kernel file of the first operating system executes and mounts the file system of the first operating system, the client starts the first operating system through the file system, and the first operating system reads the menu file on the second server , providing the client with a menu to select the second operating system that needs to be run; S4, the client selects the second operating system that needs to be run; S5, the first operating system is downloaded from the second server and simultaneously executes the second operation selected by the client system. The method can solve the incompatibility problem of the network booter for machines with different instruction sets and architectures without adding additional overhead or hardware investment, and realize generalized multi-system selective booting.

Description

technical field [0001] The invention relates to a method for starting an operating system, in particular to a method for starting an operating system based on a network. Background technique [0002] In order to facilitate the centralized management and maintenance of the operating system for desktops and thin clients, the operating system is often started in the network mode. The common way to start the network is that the BIOS adopts the PXE protocol. This protocol can obtain the server address and start the file, start the operating system from the server after downloading the startup file and executing it. The activated operating system can be directly used for work or system installation and deployment, which can simplify the management and maintenance of the entire computer network. [0003] Usually, the PXE protocol needs to include several types of services in the connected network: IP address service, file download service, and network file service. The PXE protoco...

Problems solved by technology

[0008] At present, the main method of network booting is to load a dedicated Net Bootloader (Net Bootloader) from the network through the PXE protocol to select the boot system. Applicable to machines with different instruction sets and architectures, lack of versatility

[0009] There is also a startup scheme that supports multiple network systems by downloading, explaining, and executing scripts, but this scheme needs to add an additional read-only memory (ROM) or erasable programmable read-only memory (E PROM) on the client computer. The system or interpretation program used to execute the script is pre-burned in the memory. This method increases the cost of the client computer and increases the complexity of the client computer startup phase. This method requires the main CPU to execute the system in the ROM. mechanism, or use an additional CPU to execute the system in the ROM, because most clients do not have a ROM dedicated to storing the system, and there is no mechanism specially designed for the CPU to run the ROM, resulting in a lack of versatility in this method
