        Thanks, I hadn't noticed that! Actually, that part works as well, in
that the internal tcp offload engine appears to be working fine (which is what
is in the top end of the 24 bit address space), its the LCD (whose data 
bus is on the P2 port at 0xA0) that seems to have trouble and the leds on 
port 0 (at 0x80) that have issues during initialization that make me think 
thats where my problem lies.
