I have a Magitronic 286 computer, with a mfm hard drive and controller card. When I turn it on, it says incorrect configuration...run setup. press f1 to continue. When I insert a dos6 diskett and boot to it, it boots to the diskett, then when I try to go from the a:\ to the c:\, it says there is no c:\ available. It also says that msdos can't be installed to the c:\, because there is not one. I tried replacing the mfm harddrive, but it did the same thing. Would this be the controller card, or the battery? How could I check it?
