---++ PXE Boot Files Example
*Setup a TFTPBOOT server*
<br>
*TODO - needs updating*<br>
%TOC%


---++ Files
   * Location: *asimov.uwaterloo.ca:/images/exports/tftpboot*
   * Install: *rsync -aL cscf-adm@asimov.uwaterloo.ca:/images/exports/tftpboot /*

---++ Dependencies
   * CF.DNSMASQ - the dnsmasq package has to be installed and configured
   * If you are hosting a *NAT* you need CF.NatMasqFirewallExample
---++ USB version of PXE boot code
   * CF.PXEUsbKey documents how to put all of this on a USB key that you can boot

---++ Documentation
%TOC%
   * See also CF.CSApplicationServer for another detailed example
   * [[http://www.syslinux.org/wiki/index.php/The_Syslinux_Project][The Syslinux Project ]]
---++ USB Key
   * PXEUsbKey We have a USB Key setup that will let you boot all of this on a USB key
---++ PXE Server
   * DNSMASQ Configuration files */root/dnsmasq* - See CF.DNSMASQ
   * Home directory */tftpboot/pxes* is the PXE root 
   * See *~/readme.txt* for up to date detailed file and directory descriptions
   * Boot file *~/pxelinux.0*
   * Config menu *~/pxelinux.cfg/default*
      * This menu is hard coded into *pxelinux.0*
      * Note we use *~/menu.c32* as a helper for this menu
      * The line *default menu.c32* is added to the start of the *~/pxelinux.cfg/default* file to interpret  all *label* and *menu label* directive by default with the helper
   * Services this depends on
      * *dnsmasq* - see CF.DNSMASQ

---++++ /tftpboot/pxes
   * PXE root directory
   * Edit the file ~/pxelinux.cfg/default
      * Find your distributions PXE boot image - *kernel* and optionally an *initrd* for Linux distros
      * Create a unique PXE directory for the new boot image under */tftpboot/pxes*
      * Copy  your PXE *kernel* and *initrd* to this directory
      * Create entries like this <br />

---++++ /tftpboot/pxes/menu.c32.confs/
