      3 # This is an example of how to configure a small, efficient kernel for
      4 # a system with limited RAM. Even so it's capable of doing quite a
      5 # bit. The hypothetical system used for this example is a Macintosh
      6 # IIx or Macintosh IIcx with 8 MB of RAM and an 80 MB disk. One or
      7 # more DP5380- based NuBus Ethernet cards, onboard video and one or
      8 # more NuBus video cards are configured. Basic SLIP and PPP support
      9 # as well as packet filtering are available.
     10 #
     11 # This configuration is suitable for experimenting with NetBSD as a
     12 # router with one or more Ethernet cards, and up to two PPP
     13 # connections (one on each serial port).
