Diskless computer starting method based on operating system network drive

Abstract

The invention discloses a diskless computer starting method based on operating system network drive, aiming to solve the problem that the existing diskless computer starting method need to depend on bottom basic input output system (BIOS) network drive and the communication protocol. The technical scheme of the invention comprises the following steps of: firstly, generating an embedded operating system kernel; secondly, generating file system image supporting the download, the storage and the start of a target operating system; thirdly, putting the embedded operating system image into a universal serial bus (USB) device or solidifying the embedded operating system image to a Flash of a computer main board; fourthly; configuring a server; and finally, starting the diskless computer by using the network drive and the communication protocol of the operating system layer. In the process of starting the diskless computer, the embedded operating system is firstly started, and then the embedded operating system takes the charge of downloading, storing and starting the target operating system. The invention breaks through the technological limitation that the BIOS can not efficiently support network interface controller (NIC) drive and the communication protocol in time, avoids the expense for developing the NIC drive and the communication protocol in the BIOS, and has lower expense.

Description

technical field [0001] The invention relates to a method for loading and running an operating system on a diskless computer. Background technique [0002] Usually, the operating system of the computer is loaded and started using a disk-based boot method, which is often referred to as a "disk boot" method. In the disk boot mode, the computer has a local disk, and the firmware program Firmware on the main board or the basic input and output system BIOS (Basic Input Output System) directly loads the boot program Bootloader from the boot area of ​​the local hard disk during startup, and then is loaded by the Bootloader and start the operating system. However, in many application fields, computers do not have local disks, and these computers without local disks need to adopt a "diskless boot" method of loading and running an operating system from a remote server. [0003] The diskless boot method has the characteristics of simple maintenance and high security. The main applicat...
