puuuuuuuh .... right out of my head i remember such a tab called "Nios II More CPU settings" but that is ages ago. Quartus 5.1 or 6 ... and i remember that this tab was removed ....
is this tab visible for you until you change something or not there at all ?
is it available in other projects ?
or do you have some kind of manual that that tells you to change something on such a tab ?
i think the more cpu settings is no included in the nios processor dialog. sorry that i am unshure but that page was formaly used to setup reset address and interrupt address ... now part of the cpu property page
