   ip65 MAC address issue - is Oliver Schmi   
   03 Jun 21 00:31:00   
   
   I ran into a strange problem with IP65 running on Apple //e with   
   Uthernet-II. The IP65 code hard-codes the Uthernet-II MAC in the file   
   drivers/w5100.s to value 00:08:DC:A2:A2:A2. However, when I run an IP65   
   program such as DATE65, it sometimes makes its DHCP request with this MAC   
   and sometimes some other MAC (usually 00:08:DC:11:11:11, which just so   
   happens to be the default for Contiki. I don't see anything fishy in the   
   code, and I can't explain this behaviour.   
      
   In an effort to investigate I ran the PLASMA 2.0 'httpd' demo, which has   
   it's own IP stack and uses some other value for the MAC.  After running the   
   PLASMA httpd, I then ran IP65 and it used MAC 00:08:DC:A2:A2:A2, as coded.   
   A few runs later it was back to :11:11:11. Could be random, I don't have   
   enough datapoints to know for sure.   
      
   The reason I am messing with this is I have more than one Apple II with   
   Uthernet II on my LAN, and I can't have them using the same MAC ;) I was   
   thinking to add the MAC address to the ETHERNET.SLOT file that IP65 uses.   
   However, first I need to get it using the correct MAC as coded.   
      
   Hoping Oliver Schmidt gets to read this and can give me an idea what is   
   going on.   
      
   All the best,   
   Bobbi
