Probably, You are searching for the resistors to remove to disable half of the on board RAM. You have to remove just one resistor, the one in the RAS line (without RAS a RAM will stay in Tristate forever). RAS is pin 4 (four) of the 41 256 chips on the board and pin 3 (three) of the megabit chips. The RAS of the 256 chips must be disconnected from the MCU to disable them. hase -- Hartmut Semken, Lupsteiner Weg 67, 1000 Berlin 37 hase@netmbx.UUCP Dennis had stepped up into the top seat whet its founder had died of a lethal overdose of brick wall, taken while under the influence of a Ferrari and a bottle of tequila.
