Even if you are only using Access you should note that the AUNMsgs module is required this module is loaded from the 13 EtherLan card by default and must not be Unplugged O Compatibility and Support AUN and TCP IP The 13 EtherLan card can be used with both Acorn s Universal Networking AUN and their TCP IP Protocol Suite The card incorporates the latest released versions of Acorn s networking software and in particular of the Internet module used by Acorn s TCP IP protocol suite Because of enhancements in this module it is not compatible with Release 1 of the TCP IP suite If you are still using this software release you should contact your dealer about upgrading to Release 2 this is the only version now supported by Acorn There are no similar compatibility problems with using the Acorn AUN software However if you are using the Level 4 file sever software please note that Release 3 is the earliest version which Acorn support for use with AUN If you encounter any problems with Acorn networking software AUN or TCP IP you should indicate to your dealer or whoever is providing you with technical support that you are using the DC 4 compatible software release You should also supply the version number of the Internet module this can be found by pressing F 12 and entering Help Internet The Internet module and associated software modules are produced by Acorn Computers and are supplied by i3 under licence AUN Configuration Si

It may also be necessary to reset any Level 4 file servers on the network Each station on a particular network segment must be given a unique station number You should keep a record of the number you allocate to each station Typing netstat at the command line prompt obtained by pressing F12 will display the current station number Note The Netstat command will only work after rebooting your machine with the i3 EtherLan card installed and BootNet configured on see next section Refer to the A UN Manager s Guide and AUN Explained documents for further information on choosing station numbers Configuring the computer to boot the AUN software from ROM When you first switch on your computer after installing the i 3 EtherLan card the AUN software will be loaded but will not automatically start up You need to type configure bootnet on at the prompt press F 12 switch the computer off wait a few seconds and then switch it on again This time the software will start up and the Net icon will appear on the left hand side of the icon bar You can later prevent the AUN client software from starting by typing configure bootnet off at the prompt You may need to do this if you are not using the Acorn AUN networking protocols and possibly if you are using the computer as a gateway station Where a computer it to act as a Gateway or is to be connected to a TCP IP network it is not normally necessary to configure BootNet
