I can only assume by DX jumper you meant GX jumper? It doesn't appear any of the JU-475-(put any number here) have a DX jumper. Unlike the JU-475-4 that does have EX and GX jumpers, the JU-475-5 does not. I have all jumpers set to what your "5.25 jumpers.pdf" doc from the forum suggests for the JU-475-5. And of the jumpers you mention to look at, the JU-475-5 only has a BX jumper which is the Dual Speed jumper that your doc suggests to be off. Should I try it being on? FYI, the only Pins in your doc that you suggest to be on for this model are:
