1# $NetBSD: SMALLRAM,v 1.16 2005/02/18 21:05:52 dsl Exp $ 2# 3# This is an example of how to configure a small, efficient kernel for a 4# system with limited RAM. Even so it's capable of doing quite a bit. The 5# hypothetical system used for this example is a Macintosh IIx or 6# Macintosh IIcx with 8 MB of RAM and an 80 MB disk. One or more DP5380- 7# based NuBus Ethernet cards and one or more NuBus video cards are 8# configured, and basic PPP support is available. This configuration is 9# suitable for experimenting with NetBSD as a router with one or more 10# Ethernet cards, and up to two PPP connections (one on each serial port). 11 12include "arch/mac68k/conf/std.mac68k" 13 14#options INCLUDE_CONFIG_FILE # embed config file in kernel binary 15 16#ident "SMALLRAM-$Revision: 1.16 $" 17 18maxusers 8 19 20makeoptions COPTS="-O2 -m68030" # Optimize for the MC68030 21 22# CPU support.
