Hm, this is a bit abstract. Can you explain the difference between PXE and "normal" servers like I'm five?

I'll try Basically, PXE servers are made up of two pretty much independent and normal parts: a DHCP server, and a TFTP server.

The thing that combines them into a PXE server is that the DHCP server is configured to give out the TFTP server's details. When a client PC is told to boot from the network, it gets a DHCP address, uses the information provided by the DHCP server to download a boot file from the TFTP server, load it into memory and boot from it. In other circumstances, this information is ignored
