I am at the point now where if I can't find a PCI or ISA card to test the MOBOs FDD onboard controler, I will just have to believe that the MOBO will have to be replaced inorder to have an FDD in this computer. Tried many of the tests, tested all the parts I could, test, that my limited tools and experience would allow me to test. When it all, seems to point in one direction, logic dictates this is the problem, but maybe that's only for the race track. There are some really great Techs here at TSG, and at 50 I enjoying building new Computers. It's when you have a computer that you can't find an answer for a problem, you get to know quite fast in this game, who the real techs are. Like me, the ones who just want to keep their hands busy, and maybe do something you like, to make some extra spending money. However when something like as simple as a floppy not working, can stop you dead in your tracks, you become a parts changer, not a Master Tech. The right tools, how to use them, and an intimate knowledge of all the systems that is what makes a Master Tech. All in all it is a lot of fun to build and upgrade Computers, so I think I will stick with it and see if this old dog can still learn some new tricks. After all I am an Organic Farmer for my Day job so I won't starve. Thank you for all the help Candy, you did ask all the right questions, I just have a problem that can not be fixed with the limited tools and understanding of the complexities of the motherboard and it's systems. As this thread is keeping you from working with problems that can be fixed, I think it would be best if we put this, unsolveable problem to rest. What do you think? Marturo
