A real Linux kernel will run on your system <strong>alongside</strong> Windows. CoLinux is a system that consists of a Windows kernel driver, a Linux kernel and some userspace daemon programs. When the colinux-daemon.exe is started, it will parse the given config file, load the linux.sys (Windows) kernel driver and tell it to reserve the specified amount of RAM for the Linux system. Then the daemon loads the Linux kernel in the reserved RAM area and starts it. The Linux kernel is a slightly modified version of the standard x86 kernel. It has been stripped of all parts that directly access the hardware. Instead the kernel uses (with the help of linux.sys) either defined APIs in the Windows kernel or user space programs to access needed resources like storage or network. </p><p>This approach has the advantage, that there is no need for virtualization or emulation. The system behaves (from the user space point of view) like a normal Linux system, because there is one.</p><p>There are of course also some disadvantages:</p><p>The biggest disadvantage is that coLinux runs aside the Windows kernel. It runs on the same hardware abstraction layer that is also called ring0. Inside this CPU abstraction layer, there is no hardware memory protection. This is the same situation as between the Linux or Windows kernel and their device drivers. So a problem in the Linux kernel can bring the Windows kernel down, if Linux violates the Windows address space. Also there are security implications. If a malice user gains root access inside coLinux he can compromise the security of the Windows system as well. Also to load and use coLinux the user has to have administrator rights. (There is the possibility to start coLinux as a service, so it is possible to start coLinux as a normal user, if the user has been granted the right to start the service)</p></div><!-- SECTION [1-2036] --><h3><a name="colinux_installation" id="colinux_installation">CoLinux Installation</a></h3><div class="level3"><p> If you have something different, than an Intel compatible CPU with either a Windows XP or a Windows 2000 based operating system, <strong>coLinux will not work</strong>.

Now make sure that you have the following files located in these specific directories: </p><pre class="code">/colinux/coLinux_setup_rc6.exe/colinux/readme.doc/colinux/extra/PuTTY-setup.exe/colinux/extra/Xming-setup.exe/colinux/sources/colinux-0.7.1-hn4.src/colinux/sources/file-utils/colinux/images/tardump.tgz</pre><p> </p><p>Now to start the installation procedure, double click the coLinux_setup_rc6.exe icon in the colinux directory. You should receive a welcome screen that looks like this:</p><p><a href="media/colinxwelcome.png" class="media" target="_blank" title="colinxwelcome.png"><img src="media/colinxwelcome.png" class="media" alt="" /></a></p><p>Now Click on the <strong>Next</strong> button.</p><p>You will then be brought to the coLinux Licenses agreement screen. </p><p><a href="media/colinuxterms.png" class="media" target="_blank" title="colinuxterms.png"><img src="media/colinuxterms.png" class="media" alt="" /></a></p><p>Here you should read the documentation and <strong>accept the agreement</strong> and then click <strong>Next</strong> if you wish to continue.</p><p>You will then be brought to an information screen which provides the following warning: </p><pre class="code">You should know, that this software installs a Windows kernel driver, that loads a Linux kernel to run aside the Windows kernel. This software can destabilize or crash your system!!You should therefore not use software or edit data, that is vital for you or your business, while running coLinux.</pre><p>After you have read this click the <strong>Next</strong> button to continue the installation.</p><p>You will then be prompted for the directory that you want bfin-colinux installed in (the default is C:\bfin-coLinux). <acronym title="Gigabyte">GB</acronym>’ After entering this information click the <strong>Next</strong> button.</p><p>Next you will be brought to the <strong>Ram and block size selection screen</strong>.</p><p><a href="media/colinuxram.png" class="media" target="_blank" title="colinuxram.png"><img src="media/colinuxram.png" class="media" alt="" /></a></p><p>Here you have to select the size of the actual installation and the amount of RAM, coLinux should use. The coLinux RAM is <strong>exclusively</strong> used by coLinux and will no longer be available for Windows (only as long as coLinux runs). You should reserve as much as possible, where a <strong>minimum</strong> should be <strong>128MB</strong>. You have to remember, that Windows also needs RAM and it should have <strong>at least 128MB</strong> left. For example if you have 256MB, you could try to use 128MB (It is possible, that Windows would not allow coLinux to use that much RAM. If that is the case, try 96MB). If you have 512MB then 256MB or 320MB would be a good idea. Also you should remember that if Windows does not have enough RAM for smooth operation then it will slow coLinux down and could destabilize your system. <strong>Also you should not run unnecessary Windows software, while working with coLinux</strong>. You should also select a bigger swap size than you have selected the RAM size.</p><p>The coLinux standard installation uses about <strong>750MB</strong> space on the rootfs. So you should <strong>at least</strong> select <strong>1GB</strong> for the root file system. If you want to install additional software, you should select it bigger. For the home filesystem, you should select <strong>at least</strong> select <strong>1.8GB</strong>, since you will be installing the uClinux distribution here.</p><p> The next step is to select an IP address for coLinux and install the tuntap driver. </p><p><a href="media/colinuxtap.png" class="media" target="_blank" title="colinuxtap.png"><img src="media/colinuxtap.png" class="media" alt="" /></a></p><p>If this is your first coLinux installation, you should check the <strong>Install a TAP driver</strong> box and select an IP address for the Windows side of the TAP. It should be an address in a not yet routed class C subnet in the address space of 10.xxx.xxx.xxx or 172.16.xxx.xxx or 192.168.xxx.xxx. (An example of a class C network is 10.12.12.xxx).</p><p>There is also an option for serial support. If you activate it, you should also select the right COM port. You should also know, that the console will block, while using the serial port. So you have to use a xterm or PuTTY, while working with the serial port. Now you may hit the <strong>Next</strong> button to move on with the installation.</p><p>In the next step you can select a different start menu folder name. After you have done this hit <strong>Next</strong>.</p><p>The final step allows you to select additional tasks to install. If this is your first installation, you should select the <strong>PuTTY</strong> ssh client and the <strong>Xming X-Server</strong> to be installed. You can also select the profile for PuTTY and the service if you want.</p><p><a href="media/colinuxputty.png" class="media" target="_blank" title="colinuxputty.png"><img src="media/colinuxputty.png" class="media" alt="" /></a></p><p>If you confirm the installation by hitting <strong>Next</strong> and then <strong>Install</strong>, the setup starts. You can see how the installer installs some files. After a few seconds a new window opens. This is the coLinux console. This is part of the installation process. You are now seeing a small Linux system that installs the main system. <strong>This will take some time</strong>. After a few minutes the window closes and the setup continues with the PuTTY and Xming installation. Maybe Windows asks you if you want to install a driver which is not certified by Microsoft. You should answer this with <strong>Yes</strong>. When the additional software components have been installed, the coLinux setup shows some information and then goes to the login in screen. Now you have successfully installed coLinux. </p></div><!-- SECTION [2037-8822] --><h3><a name="colinux_basics" id="colinux_basics">CoLinux Basics</a></h3><div class="level3"><p> The system consists of a set of Windows drivers linux.sys.
