SGI Indigo2 Network Boot

I have gotten hold of an old Silicon Graphics Indigo2, a beautiful piece of machinery. While attempting to recover the root password, the harddisk failed. But by some extreme luck, I managed to create a copy of the root filesystem before this happened. By using an SGI manual and lots of trial and error, I finally managed to boot IRIX and run the entire thing over the network from some Linux boxes. I have written down everything required to configure this in a LaTeX typesetted PDF document here.

Here's a photo of the desktop of IRIX 5.3, the UNIX used by SGI:
