How to Setup an IPXE Server on Raspberry?

[NiKiZe]

Maybe it helps if we clear up that there is no "iPXE server" software.

If you already have some kind of PXE setup. it should be easy to just put the undionly.kpxe file of iPXE in your tftp path and point your dhcp server to that filename instead. If you don't want to compile from sources your self then you can find precompiled versions of iPXE at http://boot.ipxe.org

iPXE can be booted in different ways, the simplest to test the basics might be to create a USB drive that you boot from.
But in the end what you want is probably to chainload into iPXE, you need 2 services to do this:
* DHCP server
* TFTP server
These can be in separate processes, or in the same.

The basic documentation for setting up a good config for iPXE are located at http://ipxe.org/howto/chainloading
This recommends the ISC-DHCPD service which is the de-factor reference implementation of DHCP servers
To this you also need a TFTP service, such as atftpd or similar.

One other option is to use dnsmasq, there is some examples of users running that here on the forum.

You can find more information about all of this at http://networkboot.org/fundamentals/
