I recently installed 128 mb RAM in the last open slot. Now I can't see my 2 CD drives. They are both tied to the Secondary IDE. I removed the cover again to make sure the plugs on the IDE cables were in all the way, and they were. When I go to Device Manager, under "IDE ATA/ATAPI Controllers", it list the Intel Master IDE controller and the Primary IDE Channel. It no longer list the Secondary IDE channel. Any ideas?
