Avanti uses the EWA0, EWB0, and EWC0 network devices.  Porting a system that uses different network controllers will require reconfiguration of the network settings in VMS to support the EWnn adapters.  Here is a simple set of steps to accomplish this for DECnet Phase IV and Digital/Compaq/HP TCP/IP services.

1)Disable the DECnet (STARTNET.COM) and TCP/IP (UCX$STARTUP.COM) startups in SYSTARTUP_VMS.COM.  Comment out commands similar to these:

$ IF F$SEARCH("SYS$SYSTEM:NETACP.EXE") .NES. "" THEN @SYS$MANAGER:STARTNET

$ @SYS$MANAGER:UCX$STARTUP.COM

$ @SYS$MANAGER:TCPIP$STARTUP.COM

2)Reboot VMS.

3)Run NETCONFIG.COM and reset the DECnet parameters.

4)Enable DECnet startup in SYSTARTUP_VMS.COM (STARTNET.COM).

Note:It is very important that DECnet services start before TCP/IP services.  Some VMS startup configurations submit DECnet and TCP/IP startup commands as batch procedures.  This practice should be discontinued; the startup calls should be executed directly from the SYSTARTUP_VMS procedure as inline commands.

5)Reboot. DECnet and LAT should now come up normally.

6)Run UCX$CONFIG.COM or TCPIP$CONFIG.COM and reset the TCP/IP configuration.

7)Enable TCP/IP in SYSTARTUP_VMS.COM (UCX$STARTUP or TCPIO$STARTUP).

8)Reboot. TCP/IP should now come up normally.
