PXE Remote boot to install windows over network?

I’m reading this great how-to http://www.lockstockmods.net/2008/04/25/install-windows-over-network-with-pxe/2/ so I can learn how to install windows over a network and it looks like it makes me download TFTP which is like a DHCP server with PXE built into it.


How can I setup Mikrotik to do this?
