After completing the Area-M mission, save and do not leave the area after sending your mission report. Instead go to the other side of Transerver where it reads Area-N. Go to the second floor of the stage and keep going until you see re-appearing metal floor steps. Proceed further until you see a floor of spikes. More of the metal floor steps are there, but it is faster with Model HX. After that there is a door. There you will fight Omega Zero. ZX and at least two or three Sub-Tanks are needed to defeat Omega Zero. After he is defeated, go back to where you started to get to Area-N. Go to the third floor until you see two doors that require Megaman Zero 3 or Megaman Zero 4 in the cartridge slot. Beyond those two doors is a room with a mysterious floating rock. Get it, then get out of the area. The model can only be used after completing the game and playing your cleared saved game file. When doing this, talk to Flueve and give him the mysterious rock. He will confirm it is a BioMetal. You are now in possession of BioMetal OX.
