    ^   READ BOOTBLOCK   ^
    ^^^^^^^^^^^^^^^^^^^^^^
    Loads a disk  bootblock  in  memory  buffer.   You  can  select all the
    available drives that are connected to your Amiga.
    The bootblock is read and displayed  in  the main window in ASCII form.
    If the bootblock can't be read (Wrong  disk format, or damaged disk), a
    reqtools requester will appear and inform  you that the bootblock can't
    be read.  So the previous buffer will be displayed.
