    Not sure if this is fully relevant, I always pick up on any ADF diddling.

    Although your IBM 6157 tape installs successfully, you may see
    the following error message when your system boots up:

    WARNING: first reset no good
    ERROR: tape controller (type X) not found

    To correct this error, you need to inspect the DOS reference file
    @DFBF.ADF. This file is found on the IBM reference diskette, and
    contains configuration details for microchannel tape controllers.

    The file should read as follows:
    Adapterld ODFBFh
    AdapterName "Streaming Tape Adapter Card"
    NumBytes 2
    FixedResources
    POS[O]=OOOOOlOXb
    POS[l]=OOOOOOlOb
    io 3120h-312fh
    int 6

    If your file differs in any way from the above, modify it accordingly.
