===Setup PXE Booting===
 +
 +
Some rough notes on setting up PXE booting for linux using syslinux
 +
 +
https://wiki.syslinux.org/wiki/index.php?title=PXELINUX
 +
 +
To use a menu we need a copy of pxelinux.0
 +
 +
From the syslinux wiki link above:
 +
 +
On the TFTP server, create the directory "/tftpboot", and copy "pxelinux.0" (from the Syslinux distribution) and any kernel or initrd images that you want to boot.
 +
[5.00+] Also copy "ldlinux.c32" from the Syslinux distribution to the "/tftpboot" directory on the TFTP server.
 +
Finally, create the directory "/tftpboot/pxelinux.cfg". The configuration file (equivalent of syslinux.cfg -- see the SYSLINUX FAQ for the options here) will live in this directory.
 +
 +
The actual linux image needs to be extracted here:
 +
/tftpboot/images/{name_of_distro}
 +
 +
====Menus====
 +
 +
We can create a menu system with sub menus as well.
 +
 +
Yu will need this from the syslinux ISO:
 +
 +
/tftpboot/com32/vesamenu.c32
 +
 +
You can add a background image like this:
 +
 +
/tftpboot/images/graphics/background.png
 +
 +
 +
Example /tftpboot/pxelinux.cfg/default:
 +
 +
<pre>
 +
menu title --== SME Linux, PXE Main Menu ==--
 +
menu background graphics/background.png
 +

 +

 +

 +

 +
 +
label linuxmenu
 +
menu label ^Linux Boot Disks Menu
 +

 +
append pxelinux.cfg/linux_boot_disks
 +
 +
label Arch
 +
menu label ^Arch Boot Disks Menu
 +
kernel com32/vesamenu.c32
 +
append pxelinux.cfg/arch
 +
 +
label bootimg
 +
menu label ^Other Boot Images
 +
kernel com32/vesamenu.c32
 +
append pxelinux.cfg/bootimg
 +
</pre>
 +
 +
We then need to create separate sub menu configuration files in the same directory. Note the use of NFS is required for some of the setups here.
 +
 +
{{Note box|These are old configs that have not been tested recently but should give an idea. Please update with any recent information}}
 +
 +
Sample for /tftpboot/pxelinux.cfg/linux_boot_disks
 +
 +
The symbol ^ as per eg "Back to ^Main" is used to create an underlined shortcut key M in this instance.

===Voip Phones===
 +
 +
You can use tftpd with your Voip phones.
 +
 +
More advanced phones will allow you to choose a directory for your firmware where. More basic phones may not be able to you anything other than the default root directory.
 +
 +
e.g
 +
I have some old Mitel phones use /tftpboot only
 +
I have a number of new Grandstream phones that can load from /tftpboot/some_directory
 +
 +
Most Voip phone scan read a config file based on their MAC address to configure themselves during boot.
 +
This can takea while to set up but is a massive time saver.
 +
 +

 +
This can aid with basic tftpd setup.
 +
 +
There is also a distro called [https://sourceforge.net/projects/thinstation/ Thinstation] This PXE it's own Linux distro that can be used a thin client.
