Additionally, if you find TFTP to be somewhat slow, then you can use use
I net boot MiniMyth using HTTP not TFTP. Rather than using PXE to load
the kernel and root file system, I use PXE to load gPXE
<http://etherboot.org/wiki/index.php>. After that, gPXE loads the kernel
and root file system image using HTTP.
