INTRODUCTION(2015)
============
ucore labs was used as OS Experiments in OS Course Of Dept. of Computer Science & Technology, Tsinghua University.

ucore is a teaching OS which is derived from xv6&jos in MIT, OS161 in Harvard and Linux.
ucore was developed and used in Department of Computer Science & Technology, Institute for Interdisciplinary Information Sciences, Tsinghua University.

WORK IN MS WINDOWS
==================
Working in Linux is encouraged. But If you like to work in MS Windows, we provide virtual machine environment (Runnint Ubuntu in VirtualBox) in
Windows to help you to finish the labs. If you don't want to install ubuntu and other softs to finish these labs in Windows, you can use 
VirtualBox soft (https://www.virtualbox.org/) and a virtual disk image with all these softs. Below example is shown how to setup lab environment in Windows.
You can download this virtual disk image -- oslabs_for_student_2012.zip (576.2MB,) from  http://pan.baidu.com/share/link?shareid=69868&uk=2585194235, which
is an VirtualBox disk image (contains ubuntu 12.04 and needed softs, and is zipped with zip and xz format), and can be unzipped 
by haozip software (http://www.haozip.com). 
After unzip oslabs_for_student_XXX.zip, you will get 
---
C:\vms\ubuntu-14.04.vbox.xz
C:\vms\ubuntu-14.04.vmdk.vmdk.xz
C:\vms\ubuntu-14.04.vmdk-flat.vmdk.xz
---
then you will continue unzip all these files, and get
---
C:\vms\ubuntu-14.04.vbox
C:\vms\ubuntu-14.04.vmdk.vmdk
C:\vms\ubuntu-14.04.vmdk-flat.vmdk
---
If you installed VirtualBox soft, then the last step is: double clik file "ubuntu-12.04.vbox" and run ubuntu 12.04 in VirtualBox.
In ubuntu 12.04 login Interface:
username: chy
password: <SPACE KEY>

After you login, you will see the directory ucore_lab in HOME directory.

TESTED ENVIRONMENT
==================
UBUNTU 14.04: GCC-4.8.2 CLANG-3.5
FEDORA 20: GCC-4.8.2

EXERCISE STEPS
==============
0 Get the newest os lab src codes/docs.(Insure you can connect to github in ubuntu running on VrtualBox)
0.1 If you try to get all codes
  $rm -rf ucore_lab
  $git clone git://github.com/chyyuu/ucore_lab.git
  $cd ucore_lab
0.2 If you gloned ucore_lab and only try to get the updated codes
  $cd ucore_lab
  $git pull
1 $cd labX  
2 read codes (specially the modified or added files)
3 add your code
4 compile your code
  $make
5 check your code
  $make qemu
OR
  $make grade

6 debug your code
  $make debug

7 handin your code
  $make handin

OPTION
==============
Now, ucore suuport LLVM/Clang-3.5 + 
in step4:
  $ USELLVM=1 make
then you will use clang to compile ucore

GRADE/RANK
==========
Superman: Finish all OS labs in one month by yourself
Master: Finish all OS labs in two month by yourself
Veteran: Finish all OS labs in three month by yourself
Apprentice: Finish all OS labs in one semester with other guy's help
