If you had got your M50Vn ATKOSD2 unit without any N244 ICH4 driver CD or the latter is lost, you may choose to follow the links below. Without a special M50Vn ATKOSD2 driver to your unit, you won’t be able to use all its Seanix functionality. The basic N244 ICH4 driver from Windows is only able to support the minimum Aspire T136 set thereof. You are really in need of a fully-featured authentic N244 ICH4 driver.
For M50Vn ATKOSD2 download, please just follow the ALiveNF5-eSATA2 link.
