Some of our key routers boot entirely diskless off of an internal
fileserver (which obviously needs to be configured to not need
internet access in order to get going!). No floppy, CD-ROM, hard disk
etc. Simple enough to set up but not good for Ma & Pa, who probably
don't have a file server they want to leave running all the time.

For older machines, or for network interfaces with no boot ROM support,
it is necessary to boot from a floppy to get the network boot loader
up and running.

Uses BootP/DHCP, TFTP (not the standard one, though!) and Etherboot.

As for Web-based admin - forget it. All done with vi on the file server.
The routers pull down a specially configured kernel and initial RAM disk
and don't otherwise mount any other file systems. They log to a logging
host (which could be the boot-up file-server!).
