 2.2 Drive letters
 =================
 
 The meaning of the drive letters depends on the target architectures.
 However, on most target architectures, drive A is the first floppy
 drive, drive B is the second floppy drive (if available), drive J is a
 Jaz drive (if available), and drive Z is a Zip drive (if available).  On
 those systems where the device name is derived from the SCSI id, the Jaz
 drive is assumed to be at SCSI target 4, and the Zip at SCSI target 5
 (factory default settings).  On Linux, both drives are assumed to be the
 second drive on the SCSI bus (/dev/sdb). The default settings can be
 changes using a configuration file (SeeConfiguration).
 
    The drive letter : (colon) has a special meaning. It is used to
 access image files which are directly specified on the command line
 using the `-i' options.
 
    Example:
       mcopy -i my-image-file.bin ::file1 ::file2 .
 
    This copies `file1' and `file2' from the image file
 (`my-image-file.bin') to the `/tmp' directory.
 
    You can also supply an offset within the image file by including
 `@@'OFFSET into the file name.
 
    Example:
       mcopy -i my-image-file.bin@@1M ::file1 ::file2 .
 
    This looks for the image at the offset of 1M in the file, rather than
 at its beginning.
