+/* Network environment configuration file for the On Time RTOS-32 RTIP-32
+   demos.
+
+   By default, the RTIP-32 demos use static IP address assignment. If this is
+   not what you want, uncomment either #define AUTO_IP or #define DHCP. In all
+   cases, make sure the IP addresses (NetMask, TargetIP, DefaultGateway,
+   DNSServer, etc) given in the respective section below are all correct for
+   your select and LAN configuration. If you choose to use DHCP, the library
+   Dhcpc.lib must also be linked.
+
+   Please define symbol DEVICE_ID to match your target's ethernet
+   card and make sure that the card's hardware resource assigments are
+   correct (for PCI cards, the drivers will determine this information
+   automatically).
