     The "ethernet card description" is the name of an Ethernet interface.
     There are two approaches to networking with Basilisk II:

       1. Direct access to an Ethernet card via the "sheep_net" driver.
          In this case, the "ethernet card description" must be the name
          of a real Ethernet card, e.g. "eth0". It also requires the "sheep_net"

       2. Putting Basilisk II on a virtual Ethernet via the "ethertap" device.
          In this case, the "ethernet card description" must be the name
          of an ethertap interface, e.g. "tap0". It also requires that you
          configure your kernel to enable routing and the ethertap device:
          under "Networking options", enable "Kernel/User netlink socket" and
          "Netlink device emulation", under "Network device support", activate
-         "Ethertap network tap". Next, see /usr/src/linux/Documentation/
-         networking/ethertap.txt for information on how to set up /dev/tap*
-         device nodes and activate the ethertap interface. Under MacOS,
-         select an IP address that is on the virtual network and set the
-         default gateway to the IP address of the ethertap interface. This
-         approach will let you access all networks that your Linux box has
-         access to (especially, if your Linux box has a dial-up Internet
-         connection and is configured for IP masquerading, you can access
-         the Internet from MacOS). The drawback is that you can only use
-         network protocols that Linux can route, so you have to install and
-         configure netatalk if you want to use AppleTalk.

+          - insert "#define CONFIG_ETHERTAP_MC 1" near the top (after the

+           tap0 -seed -phase 2 -net 2 -addr 2.47 -zone "Basilisknet"
+
+         (the "47" is an arbitrary node number). This will set up a zone
+         "Ethernet" (net 1) for the Ethernet and a zone "Basilisknet" (net 2)
+         for the internal network connection of the ethertap interface.
+         MacOS should automatically recognize the nets and zones upon startup.
+         If you are in an existing AppleTalk network, you should contact
+         your network administrator about the nets and zones you can use
+         (instead of the ones given in the example above).
