    Default Tandy 2800HD fails to boot

    I dug my Tandy2800HD put of storage (it worked fine back when it went into storage!) but it doesn't boot up. Invalid setup. What a surprise. When I tried to get into the BIOS setup, I couldn't. With a bit of reading of the documents I have, I now remember that the program SETUP_28 is on the HD, not in the BIOS chip. How to get to it if the system does not boot up onto the HD? I dug out my trusty 3.5 inch MSDOS boot disks for 3.3, 5.0 and 6.0. Nope. the floppy drive makes a noise like it's pulling the head back to track 0, but it doesn't work either.

    Am I doomed? Is my only option disassembly and parts swapping now?

    Your thoughts and advice are welcome.

    Thanks for listening!

    Your floppy probably needs to have its band replaced, its on the underside of the drive. Once you do that, you need to boot a disk that has the setup program on it, run it, tell it what kind of HDD is in there, and it will boot off the HD again.

    Thanks Paralel.

    Looks like some disassembly is in my future.
