Ye, sounds like a fun game ;-)

See bottom for via-diag outputs.

It looks as thought your I switchs do not fix the prob. There is still 
no Station address (00:00:00:00:00:00). The next thing I did was 
look at the working output again:-

I noticed that the mac address was stored in the registers and 
eprom. I guess it would not be as easy as just writing the mac 
back in the blank eprom and registers?

Is there a reset 'thing' for thses chips, that sets them back to 
factory tests (like switching them off)?

So.....How do I go about playing this game?
