  I am getting tired of people making statements like the above with 
no explanation.  The only thing I have been able to pin down about int 2 is 
that the EGA board uses it, if properly enabled.  With that assumption, 
I proceeded to install an Excelan board and uPort driver on int 2 (ALL the 
others were used) and I have had NO problems with it.
  I then proceeded to try the same interupt with Wollogong's (buggy) TCP 
software with a 503 board and NSE, and the board refused to work until I 
changed interupt levels.
  Any ideas as to what is really going on?
