SMALLRAM revision 1.10
1 # $NetBSD: SMALLRAM,v 1.10 2004/09/04 23:29:50 manu 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 12 include "arch/mac68k/conf/std.mac68k" 13 14 #options INCLUDE_CONFIG_FILE # embed config file in kernel binary 15 16 #ident "SMALLRAM-$Revision: 1.10 $" 17 18 maxusers 8 19 20 makeoptions COPTS="-O2 -m68030" # Optimize for the MC68030 21 22 # CPU support.
