Why do we need PXE?
PXE (Pre eXecution Environment), affectionately pronounced Pixie (as in fairy dust), is a method of having an end computer (client) boot using only its network card. Using the “PXElinux” NBP, it is possible to setup the server for more then just one PXE boot program for our clients.
What is PXE in Linux?
