   Micro-SpartaDOS 4.5 (MSDOS.COM)
   ==============================

By Jiri Bernasek - BEWESOFT

------------------------------------

  Micro-SpartaDOS allows you to load
games (which needs a micro-DOS) from
a disk in SpartaDOS format. So, you
can now keep games on your XF 551, 
hard drives, etc.
  Version 2.2 supports also a high
speed SIO for Speedy 1050, XF 551 and
the HDI.
  Version 3.x supports multiple
drives.
  Version 4.x supports quadruple
sectors (512 bytes long). 


        1. INSTALATION

  How to install your game-Disk ?
It's easy:

a) Format your disk under SpartaDOS
   (XINIT command) - If you haven't
   formatted it already, of course.

b) Copy your games to the disk.
   (You can use for example MENU or
   XCOPY)
   If you have a drive with a large
   capacity (or other programs on
   the same disk), it'll be good to
   use subdirectories for your games.

c) Copy the file MSDOS.COM to your
   disk. (You can place it anywhere
   on the disk)

d) Use the command 'BOOT MSDOS.COM'.
   (If you haven't got the file 
   MSDOS.COM in current or main 
   directory, then you must also type
   the correct path!)
   After this, Micro-SpartaDOS will
   start when you boot your disk.
   (If you want to boot the original
   SpartaDOS from your disk, don't
   use that BOOT command. But then
   you need to start Micro-SpartaDOS
   by typing 'MSDOS'.)

e) If you want to see DOS-names in
   MSDOS's menu, protect all files
   and subdirectories that you want
   to be present in that menu. 
   (Therefore you can disable 
   displaying of other files like
   MSDOS.COM, *.DOC etc. by simply
   unprotecting them.)

f) If you don't like DOS-names, use
   MSINI.COM or MSINI3.COM in each 
   directory to create MSDOS.DAT 
   files. Then, your own file
   descriptions (from MSDOS.DAT file)
   will appear in MSDOS menu.

    - Start the file MSINI.COM
    - Insert your disk into drive #1
    - Enter the path for directory
      you want to make MSDOS.DAT in.
    - Enter your name for each file
      or subdirectory. This name
      can be up to 35 characters
      long, and there can be any
      characters (lower case,
      inverse, graphics symbols, etc.
      are possible!) 
      You can use arrows
      to move the cursor left/right,
      or the DELETE key.
      If you want to disable
      displaying of a file in MSDOS
      menu, press ESC when you are
      asked for its name. (MSINI does
      disable displaying of MSDOS
      itself [MSDOS.*] automatically)

... And the instalation is complete !


        2. STARTING UP

  So, we have installed our disk.
If you want to start a game, simply
insert this disk into your drive #1
and turn the computer on.
  After a few seconds MSDOS menu of
the main directory will appear. 
To select a game from this menu, 
simply press a letter key.
  If there are lots of games, you
need to press SPACE-BAR to see more
names.
  If you've  selected a name of a
subdirectory, new menu will appear.
To go back to parent direcory, press
'<'. You can also go directly to main
directory with '>' key.
  If you want to see all files in
a directory, press ESC. Then, all 
files with their real DOS-names will
be presented on the screen.
  If you changed the disk before your
selection, main directory of the new
disk will appear.
  You can switch current drive by
pressing keys [1]-[8]. You can access
all your Atari attached drives by
pressing [Ctrl]+[A] to [Ctrl]+[O],
what will select drives A: to O: 
(1-15, SpartDos style).

  When the game is selected, you'll
see an empty screen and the game 
starts to load...

  If you started MSDOS from SpartaDOS
(by typing MSDOS), you can return
from MSDOS menu to SpartaDOS with
the RESET key. But when you have
selected your game, the return to
SpartaDOS is possible only by booting
it again.

  Note that a High speed SIO needs
some memory for itself. So, if your
game doesn't work, try to start it
with SHIFT+letter. (This will remove
the High speed SIO...)


        3. TECHNICAL INFO

  Micro-SpartaDOS 2.2 uses only SIO
($E459) or a High speed SIO for disk
access, so it does't need any DOS.
  While selecting a file, it uses
memory area $2000-$28FF for program,
and $2900-MEMTOP for buffers, new
filenames etc.
  While loading a program, MSDOS uses
only area $700-MEMLO. The MEMLO
values for versions prior to 4.x 
are these:

   Standard SIO: $A00
         XF 551: $A35
    Speedy 1050: $A00+SIO length (=?)

  Version 4.x introduces a dynamic
MEMLO. The minimal values are:
 Single density: $8D3
 Double density: $953
 Quadruple(512): $A53

  Before loading the memory is 
cleared (not under ROM-OS).
  You can use any disk format 
supported by the original SpartaDOS
(Up to $FFFF (65535) sectors, 128, 
256 or 512 bytes per sector).

  Important! MSDOS supports only
SpartaDOS format - NOT Atari DOS.
(There are many other MicroDOSes for
Atari DOS format...)
  The only limit for number of
directory entries is the size of
memory ($2900-MEMTOP). It is about
500 files with full names, or about
1500 files with DOS-names in each
directory!


O.K. That's all I wanted to write 
about my Micro-SpartaDOS 2.2. Good 
luck in games started with 
Micro-SpartaDOS!
