-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.
