Using an Ubuntu desktop system as a PXEboot server

What happens

1. System boots.
2. System looks for a DHCP server.
3. System requests IP and some other settings from DHCP server.
4. If it gets them, it looks for a tftp file server
5. If it finds one, it asks for a file.
6. The server delivers a bootable kernel image.
7. System runs a boot script after loading the kernel.
8. The boot script tells it to get more files from the tftp server.

Packages that need to be installed

You need a dhcp server and a tftp server. The Ubuntu packages that I use are called "dhcp-server" and "tftpd-hpa". To test the tftp server, I also use "tftp-hpa".

More later... ask for help if you need it...
