*********************************************************

What is it?
===========
   A  Cross-Dos/MSH  like program.  It will allow you to
read MS-DOS disks with a standard 3 1/2 drive.

Installation:
=============
   Copy l/MultiDosFileSystem to l:
   Copy devs/multidos.device to devs:
   Execute  PcMountAll  from  Workbench or CLI(put it in
your s:user-startup).

What do I do now?
=================
   MS-DOS  disks  will now be available through dfx:  as
all other Amiga disks.



   What  is  MultiDos?  If you have heard of CrossDos or
MSH,  it  is  just  about  the same thing.  Only better,
since  you can read both MS-DOS and AMIGA-DOS disks from
the  same  Device  name  (DF0:,  DF1:,  DF2:  and DF3:).
There  is also a non standard format supported.  (MS-DOS
on  trackdisk  blocks,  gives you 880K disks.) Just note
that  880K  format is not readable on a MS-DOS computer.
It  is  possible  to  make  a mountlist entry to support
this.

   If  MultiDos are mounted as MDx:, it will steal DFx:.
This  is done to cut down the diskchange overhead.  This
will also make it possible to read MS-DOS diskettes from
DFx:.  If you mount MultiDos whith another name, it will
not steal DFx:.



System/PcMountALL
=================
Starts MultiDosFileSystem on all mounted DFx: drives.

SYNTAX
  PcMountALL

System/PcKillALL
================

  Removes MultiDosFileSystem from all DFx:  drives.  But
leaves  the  devicenodes  in  the  list  (in  case  that
somebody still have a pointer to the devicenode).

SYNTAX

  PcKillALL

System/PcFormat
===============

  This  format  command  will  try  to  get  as  much as
possible  out  of  a  disk / partition.  But if you like
cracy  formats  you  can  define  them as a entry in the
S:PcFormat.spc file.

  Spesial  care  is taken when formatting DFx:  devices.
As  default it is assumed that you want to format a disk
as  a  MS-DOS compatible disk.  But if you want to use a
non-standard   disktype   (880K   MS-DOS  FORMAT)  on  a
diskette, use the option AMIGA, when formatting.

SYNTAX
  PcFormat DRIVE <drive> NAME <name> [QUICK] [NOICONS] [NOVERIFY]
        [NOLABEL] [AMIGA] [SMALLCLUSTERS] [-f<formatname>]
  QUICK = Just initialize the disk.
  NOICONS = Dont put a 'DISK.INFO' icon on the disk.
  NOVERIFY = Don't verify disk when formatting.
  NOLABEL = Don't give the disk a name (is not recomended).
  AMIGA = forces PcFormat to use trackdisk.device when formatting
        diskettes (WARNING: not compatible with MS-DOS).
  SMALLCLUSTERS = Use 512 bytes clusters instead of 1024 bytes clusters.
  <formatname> refers to a index in the file 'S:PcFormat.spc'
FUNCTION
  Formats a diskette as a MD-DOS disk.

----------------------------------------------------------------------------
Example of a body of a entry in 'S:PcFormat.spc':

F9:					/* Format index, can be anything
					   you like, but it is recomended
					   that it differs from the
					   KeyWords below. This index
					   refers to a standard 3.5" disk */
  SystemID = MDos1.0			/* System name (8 cps). */
  BytesPerSector = 512			/* Usually 512 bytes. */
  BlocksPerCluster = 2			/* Standard is 2. */
  PreAlloc = 1				/* Number of blocks before first
					   FAT. */
  NumbersOfFats = 2			/* Usually 2. */
  NumberOfRootDirEntries = 112		/* Entries in root dir. must be a
					   multiple of 16 */
  TotalBlocksOnDisk = 1440		/* Total number of blocks on disk */
  FormatID = 0xF9			/* Format type, 0xF9 is 3.5" disks */
                                	/* 0xF8 is for hard-disks */
  BlocksPerFat = 3			/* 3 on standard diskettes. */
  BlocksPerTrack = 9			/* 9 on standard diskettes. */
  Surfaces = 2				/* 1 or 2 on a standard diskette. */
  HiddenSectors = 0			/* Internal use, leave 0 */
  BigTotalSectorsOnDisk = 0		/* If TotalBlocksOnDisk is greater
					   than 65535 then use this instead */
  PhysicalDriveNumber = 0		/* Internal use, leave 0 */
  ExtendedBootRecordSignature = 0	/* Internal use, leave 0 */
  VolumeSerialNumber = 0		/* Internal use, leave 0 */
  VolumeLabel = MultiDos1.0		/* Internal use */
##					/* End marker for index. */
----------------------------------------------------------------------------

Caveats
=======

   Don't  copy a file with name longer than 8 characters
to MS-DOS disks under 1.2/1.3 Workbench.  Workbench will
crash. Commodore has fixed this under 2.0.
