Lab goal Analyze and improve a small operating system (Pintos) and , make a deeper understanding of the principle of operating systems and implementation mechanism.

What is pintos Welcome to Pintos. Pintos is a simple operating system framework for the 80x86 architecture. It supports kernel threads, loading and running user programs, and a file system, but it implements all of these in a very simple way. In the Pintos projects, you and your project team will strengthen its support in all three of these areas. You will also add a virtual memory implementation.

Install the VirtualBox What is VirtualBox? Download VirtualBox Homepage: https://www.virtualbox.org/ Downloads: ftp://58.198.176.47/pub/oslab/ch-01/resources/VirtualBox-5.1.4-110228- Win.exe Support: Windows, MaxOS, Linux, etc. Documents: http://www.virtualbox.org/wiki/Documentation Newest version: 5.1.4 VirtualBox是一个跨平台的虚拟化应用，它可以运行在Windows,Mac,Linux等系统。在VB中可以同时运行多个操作系统，比如，在MAC系统运行Windows和Linux，在Linux系统上运行Windows。但是唯一的限制就是磁盘空间和内存大小是有限的。

Install the VirtualBox

Install the project environment Method 1: Install Ubuntu yourself on VirtualBox ! Method2: Import mirror file I have already made for you. Link : ftp://58.198.176.47/pub/oslab/ch-01/resources/oslab.ova

Method 1: Install Ubuntu Choose your Ubuntu img file ubuntu-16.04.1-desktop-amd64.iso Install Ubuntu on virtual box Choose OS: Linux 64 bit, Version: Ubuntu16.04 Memory: Share from your local memory size, e.g. 1024MB Hard Drive: Use an existing virtual hard drive file

Method 2: Import Appliance Start vbox Import the oslab.ova mirror to your virtual machine.

Setup the vbox Choose the oslab virtual machine, click Settings button on toolbar Click Storage in the left pane, and check whether the oslab is located under IDE Click Shared Folders in the left pane Click the button (Add New Shared Folder) on the right side Choose the path you want to share with oslab, and name it (and remember it!) Start the oslab, wait, user name: ’oslab’, password: ’oslab’ Open a terminal, type (and hit RETURN): sudo usermod -aG vboxsf $(whoami) Your root’s password is oslab
