Darren,
better late than never.....
Have you looked at freertr? It is the closest thing to an embedded
system based on FreeBSD that I have come across. Freertr is a
"FreeBSD Floppy Routing System" based on the FreeBSD 1.02 kernel
and...
"is basically the FreeBSD 1.02 kernel plus minimal utilities
necessary to setup a 80386 or 80486 PC as a SLIP/ethernet router.
Utilities included are: ifconfig, slattach, netstat, ps, stty, routed,
route, more, and a simple hayes style dialer.
Minimum System Requirements:
80386 or 80486 ISA or EISA motherboard
4Meg or more of RAM
3.5" 1.44Meg floppy & controller (installed as drive A:)
Keyboard
Mono or VGA adapter card [monitor if you like :-)]
0 or more serial ports, preferably 16550A UARTs
0 or more ethernet adapters
(assumed at least 2 total ethernets and/or serial ports)
Modem cables that properly support control signals
(CTS/RTS/CD)".
Swap the floppy for one of those solid-state floppy emulators I keep
seeing advertised in Circuit Cellar INK and the thing starts sounding
very embedded to me.
Although based on a very old version of the kernel, it may provide a
useful source of info.
Pick up the trail at http://www.rdrop.com/freertr/
good luck,
Peter.
