Embodiment Construction

[0026] The invention is based on the Linux system with open source code, adopts the USB startup technology, the hardware automatic detection technology, the hard disk automatic mounting technology, and provides the method for starting the Linux operating system on the mobile hard disk.

[0027] As shown in Figure 1, the steps to establish a Linux operating system in a mobile hard disk are:

[0028] Step 100: compile source code and configuration file, generate Linux kernel;

[0029] Step 101: Create Linux system directory and configuration script, generate Initrd

[0030] Step 102: Compile the source code and configuration files to generate a root file system

[0031] Step 103: Create a boot partition in the mobile hard disk, and copy the root file system, Linux kernel, Initrd, etc. to the boot partition.

[0032] Step 104: Use tool software to make the boot partition into a hard disk image

[0033] Step 105: Use the working software to copy the hard disk image to the mobil...

Abstract

The invention relates to a method for realizing starting of Linux operation system on a hard drive when the hard drive is inserted into the USB interface of PC, which is carried out by the steps of: building up a Linux operation system in a hard drive, entering the BIOS of PC, setting the start mode as USB-HDD or USB-ZIP, starting the system bootstrap routine, selecting the Linux edition, and downloading the Linux internal kernel and Initrd to the internal memory of PC from mobile hard drive, starting the internal kernel of Linux, initializing the system and loading task, entering the file system of Initrd, switching to the root file system of the mobile hard drive, detecting the hardware equipment and installing the drive program automatically and implementing the automatic configuration, starting the desk system, and after the user enters the user name and cipher, detecting and mounting the hard disk partition.

Description

[0001] Involved areas [0002] The invention relates to a method for starting a Linux operating system on a mobile hard disk after inserting a mobile hard disk into a USB port of a personal computer (PC, hereinafter referred to as PC for short), and belongs to the field of computer and information technology. Background technique [0003] The traditional mobile hard disk only has the function of data storage. When the mobile hard disk is used on other people's PCs, the personal system environment and configuration cannot be used. It is easy to be infected with computer viruses, and it is not easy to install applications on the mobile hard disk. Due to the above defects, it is limited The scope of use of the mobile hard disk. To solve this problem, one solution is to install applications on the mobile hard disk that do not need to modify the Windows system registry. These applications store personal configuration information on the mobile hard disk, so that the mobile hard disk...
