There are also builds for FreeBSD-5 and Freebsd-6 -5 http://www.ultradesic.com/index.php?section=86 -6 http://www.ultradesic.com/index.php?section=125
I use minibsd (FreeBSD-4) very successfully as a network monitor in 32M RAM, booting from a 32M CF card, with a 66MHz processor. There are two partitions on the card - the root (r/o) and /config (r/o on boot, r/w during rc.shutdown to save my configs and scripts) Runs vi, tcpdump, net-snmp....
