ive filled four free positions on 6A board wit 4256 chips, now - how i can set it as standard ram, not an extension ram? i want additional fast (slow) ram (hooked on expansion connector) at c00000 so exram jumper jp2 must be at A23. Is there any way to tell agnus there is 1MB chip as standard? Do i need some demuxes for cas/ras?

Any help will be appreciated guys, im trustin you. someone here KNOW how to do it
