                    New Features of Disk Explorer
                    ^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

        Disk Explorer  is compatible with  all IBM-DOS  and MS-DOS
        versions starting from 2.0 and including DOS 3.3, DOS 4.0,
        DOS 4.01 and DOS 5.0

        Disk  Explorer  reads  and writes  low  density  and  high
        density diskettes  in 360K,  1.2M, 720K  and 1.44M  floppy
        drives.

        Disk  Explorer  has  been  tested  on  a  variety  of  IBM
        machines, Toshiba, and  Compaq clones with hard  drives up
        to 325 Megabytes and speeds up to 50Mhz.

        Disk Explorer  can access any  sector on any  partition or
        logical drive via Track, Head,  Sector numbers or Absolute
        Sector numbers.   This includes  the partition  table, the
        boot record and all hidden sectors  on track 0 of the hard
        drive.

        Disk Explorer colors for various screens can be customized
        and saved to disk.

                       low density and high density media.


 Display directory    Press Ctrl-Home or Ctrl-End to  reach the first or
                       last lines of the display.

       Show sector    Cursor right once.

                       Press  PgUp to  reach  the  highest available  LSN
                       (logical sector number) on the drive.

                       Press PgDn to reach the  boot record of the drive.
                       Use  the grey  plus,  minus  keys to  continuously
                       change the current sector.

                       Press the grey minus key when  you are at the boot
                       record and you will see  the hidden sectors on the
                       first track of  the hard drive with  the partition
                       table.

                       Press the grey  minus key more times  and you will
                       reach the partition table.

                       CAUTION:  do NOT  edit the partition table  or the
                                 boot record unless you know exactly what
                                 you are doing and why  you are doing it.
                                 This   is   NOT  the   place   for   any
                                 experimentation.

                       Example:  Your  hard drive  has drive  C:  as  the
                       primary DOS partition.   Drive D:  and E:   are in
                       the extended  DOS partition.  The  partition table
                       will  exist below  the boot  record  of drive  C:.
                       There is no partition table  for drives D:  and E:
                       since  those  drives  are   in  the  extended  DOS
                       partition.

          Position    This  line  indicates  the  current  Track,  Head,
                       Sector  and Absolute  Sector  of  the hard  drive.
                       Absolute  sectors   are  number  from   0  upwards
                       starting at track 0, head 0, sector 1.

                       Example:  Your hard drive is composed of
                                 753 total tracks,     numbered 0 to 752.
                                 16 heads,             numbered 0 to 15.
                                 17 sectors per track, numbered 1 to 17.

                       track-head-sector   0  0   1   =   0  Absolute sector                       
                       track-head-sector   0  0   2   =   1  Absolute sector                            
                       track-head-sector   0  0   3   =   2  Absolute sector                            
                       track-head-sector   0  0  16   =  15  Absolute sector                            
                       track-head-sector   0  0  17   =  16  Absolute sector                            
                       track-head-sector   0  1   1   =  17  Absolute sector                            
                       track-head-sector   0  1   2   =  18  Absolute sector                            

     Analyze Track    Disk Explorer will perform this function correctly
                       on  360K, 720K,  1.2M and  1.44M diskettes.   Disk
                       Explorer will not perform  this function correctly
                       on  a floppy  diskette  if  the effective  machine
                       speed is greater than 33 Mhz.

            Colors    Select the  foreground and  background colors  for
                       Disk Explorer  menus, text,  status and  warnings,
                       and headers.   Cursor right  to the  desired item.
                       Press 'Enter'  to select foreground  or background
                       color changes.  Then press grey plus or grey minus
                       keys  to cycle  through all  possible colors.   In
                       foreground mode  similar colors will  be adjacent.
                       For instance, the color pairs light green and dark
                       green,  yellow and  brown, white  and light  grey,
                       will be next to each other.

                       Press F4 repeatedly to cycle through your latest color
                       choice and Disk Explorer's default color choices.

            Screen    Cursor right to 'load' item.  Use the grey plus or
                       minus keys  to toggle to  'save'.  When  you press
                       'Enter' your current color  settings will be saved
                       in  the   file  from   which  Disk   Explorer  was
                       originally loaded.  This feature works even if the
                       Disk Explorer  file is  in another  sub-directory.
                       The DOS version must be DOS 3.1 or higher for Disk
                       Explorer to find itself.  A 'success' or 'failure'
                       message will  be displayed.  If the  Disk Explorer
                       file   was  marked   read-only   then  the   color
                       information will not be saved.

                       The  next  time  you   load  Disk  Explorer,  your
                       selected colors will be used.  You may re-load the
                       colors from the on-disk Disk  Explorer file at any
                       time   by   pressing  'Enter'   when   'load'   is
                       high-lighted.
