Troubleshooting The Ethernet Drivers


"I installed the device but my network software error message returned
with: 'could not open device'."

	* Did you write a configfile?

	* Did you write a correct configfile?

	* Does your configfile contents match the jumper settings on your
	  Ethernet card?

	* Are you using AmiTCP version 3.0b2?  If so, you need to make sure
	  to read the file NOTE_TO_BETA_TESTERS.  It explains that with
	  this and subsequent versions of AmiTCP, the interface must be 
	  defined in db/interfaces.  Versions of AmiTCP after AmiTCP 3.0b2
	  have an entry for an NE2000 card used with the GG2 Bus+.  If you
	  are missing this entry in the db/interfaces file, add this to it:

	    #
	    # Ethernet adapter NE1000 on GG2 Bus+
	    #
	    ggether dev=devs:networks/gg_ne1000.device +
	     IPTYPE=2048 ARPTYPE=2054 ARPHDR=1 ARPREQ=4 IPREQ=16 WRITEREQ=16 

	* Your Ethernet card may have problems.  Try it in another machine or
	  try a different Ethernet card in your machine.

"My computer just hangs when the device starts up."

We discovered such a problem with some NE2000 compatible cards when used 
in an A2000. We solved it by adding or removing a jumper on the NE2000 
board sometimes called a "compatibility jumper" (on the Enlan 2000). 
Removing Jumper JP1 solved this problem on a Superlan 2000.  Please let
us know if you encounter this problem so we can find out what exactly 
causes it.
