I'm trying to repair an old 386 to computerize my electric train. I've a great problem with the A: drive(1.44Mo). It's impossible to boot with this drive, nothing happens... And when trying to access a disk through it, Dos "says" SEEK ERROR READING DRIVE A: What's the problem? The controller, the drive(other drives have the same reactions)? Not expert in repairing computers(in fact, my sister replaces the motherboard by another one -not her, but a friend -, and now she gives me the computer back without the new motherboard, but with the old motherboard, but all cables are disconnected. Perhaps one of the connections is wrong? ) Please help me.
