#	$NetBSD: SMALLRAM,v 1.25 2006/02/04 03:15:30 rpaulo Exp $
#
# This is an example of how to configure a small, efficient kernel for a
# system with limited RAM. Even so it's capable of doing quite a bit. The
# hypothetical system used for this example is a Macintosh IIx or
# Macintosh IIcx with 8 MB of RAM and an 80 MB disk. One or more DP5380-
# based NuBus Ethernet cards and one or more NuBus video cards are
# configured, and basic PPP support is available. This configuration is
# suitable for experimenting with NetBSD as a router with one or more
# Ethernet cards, and up to two PPP connections (one on each serial port).
