Sorry, I just did not put the problem down right way. As for the RAM. I might even give it a try, and change it, have enough 30 pin sticks. However I have a board max out (32MB), all same size, and did not have any problem before, but who knows. The chips I mentioned are right next to the test slot. They got a 32 pins each, there is 4 of them, and I just found, that next to each slot are markings: UU, UM, LL, LM. And just found out, that each chip has, among other markings, same UU, UM, LL, and LM on them. When I mixed them up, that was a reason, I am now quiet sure, why I was getting All LIGHTS ON SOLID. As I mentioned, when in proper order, I get solid green, toner light is out, solid paper out, and paper jam flashing. These are the chips I do not know what they are. Go to switch those ram sticks. It cannot hurt. And will see. Thanks for reply. Pilgrim.
