Actually, a friend of mine at work has just re-done his firewall, and built
a disk-less linux router to handle firewalling and port-forwarding. He's
booting from floppy on a modified kernel. I'm thinking of trying the same
thing...the noise from the power supply fan on my P166 firewall/ftp server
is just pissing me off. :-)
