and tell us the KSS Version like 2.2.8, 2.3.24, 3.2, 4.1. What version do you have?
Sorry, you already posted it in post #1 (ages ago): KSS V2.3.34 SP08
The dn2drv.o can be used starting with V 4.1 (I believe) and therefore your configuration of i/o's in iosys.ini is incorrect
please provide us with the information asked for
