1.  Preface
===========
Thank you very much for purchasing the Fujitsu ATAPI Magneto-Optical (MO) disk 
drive. This device driver simplifies the use of the ATAPI MO disk drive under a 
DOS 5.x/6.x, Windows 3.1 or Windows for Workgroups 3.11(WFW 3.11) environment.
This package supports the FUJITSU M25-MCA3064AP(128/230/540/640 MB) MO disk 
drive.



2.  Notes and Restrictions
==========================
2.1   Notes
-----------
(1) Do not use other third party device drivers for M25-MCA3064AP (128/230/540
    /640 MB) MO disk drive.

(2) To format an MO disk, use the attached "FJFDISK.EXE" for DOS or  
    "MOFORMAT.EXE " for Windows 3.1 (or WFW 3.11).
    See Section 2.2 below for the DOS format command(format.com) restrictions.

(3) The "Copy Disk" and "Format Disk" commands in the DISK menu of the Windows
    3.1 (or WFW 3.11) File Manager cannot be used for MO disks.

(4) Note that no error message is displayed and no operation is performed on the 
    disk if a file of 512-byte or less is written, or an attempt is made to
    create a directory on a write-protected disk under the Windows 3.1 (or WFW 3
    .11) environment.

(5) Utilities that rewrite the boot sector cannot be used on 640MB disks.


2.2  Restrictions (on the DOS FORMAT Command)
---------------------------------------------
(1) The DOS FORMAT command(FDISK.EXE/FORMAT.COM) does not support 640MB disks.
    Use the Fujitsu MO formatter (FJFDISK.EXE/MOFORMAT.EXE) which supports 128/
    230/540/640MB disks.

(2) When the FORMAT.COM is used, two or more disks cannot be formatted 
    successively if they are of different capacities or formats.  The Formatting 
    program should be terminated each time after formatting is complete.
    After formatting is complete, the following message is displayed:
    "Format another (Y/N)?"
    Select "n" to terminate the program then run the program again to format 
    another disk.



3.  Installation
================
The installation source need not be a floppy disk.
You can create a subdirectory on your hard disk, and copy all the necessary
files into the subdirectory before installation.
The following installation procedures assume that the installer is in floppy
disk drive A.
(1) Installation in a DOS environment
    1) At the DOS prompt, type A: to set the current drive to A:\.
    2) At the prompt, type the following:
       A:\DOS\INSTALL [Enter]
       The [Enter] notation means "Press the Enter key".
    3) Follow the on-screen instructions.
    4) After installation is complete, remove the floppy disk and reboot the
       computer.
    
    
(2) Installation under a Windows 3.1 (or WFW 3.11) environment
    1) Insert the installation disk into drive A.
    2) Open the "File (F)" menu of File Manager.
    3) Select "Run."
    4) Enter "A:\SETUP.EXE" in the text box and click the OK button.
    5) Follow the instructions displayed on the setup program screen.
    6) After installation is complete, remove the floppy disk and reboot the
       computer.



4.  Outline of the Device Driver : MODISKAP.SYS
===============================================
4.1  Function Outline
---------------------
The device driver supports read operations, write operations and disk changes
on the Fujitsu ATAPI MO disk drives in a DOS environment.


4.2  Operating Environment (Hardware)
-------------------------------------
The following hardware is required to use this device driver:
(1) IBM PC/AT or compatible
(2) Fujitsu ATAPI MO disk drive


4.3  Operating Environment (Software)
-------------------------------------
- DOS version 5 or later or Windows 3.1 or Windows for Workgroup 3.11


4.4  Supported Low-level MO Disk Formats
----------------------------------------
The device driver supports the following MO disks:
(1) 128MB total,   512 bytes per sector
(2) 230MB total,   512 bytes per sector
(3) 540MB total,   512 bytes per sector
(4) 640MB total,  2048 bytes per sector


4.5  Supported Logical MO Disk Formats
--------------------------------------
(1) Volume format types (partitioning methods)
    The device driver automatically detects the following three types of volume
    format, and assigns logical drive letters (such as D:).
    (a) Super floppy format
        Standard MS-DOS MO format.  The entire disk is handled as one logical
        drive.  This format is generally known as IBM format.
        Use the attached FJFDISK.EXE or MOFORMAT.EXE program to create this 
        format.
    (b) AT Hard disk format
        PC/AT-compatible machine format for dividing an MO disk into multiple 
        partitions.
        Use the attached FJFDISK.EXE or MOFORMAT.EXE program or the DOS FDISK 
        command to create this format.
    (c) NSR format
        International standard (ISO13346) for dividing an MO disk into multiple
        partitions.
        One MO disk can be divided into multiple partitions (logical drives).
        NSR is an acronym for Non-Sequential Recording.
        Use the included FJFDISK.EXE program to create this format.

    To identify the format of your disk from Super Floppy, AT Hard Disk, 
    or NSR, activate the included formatter "FJFDISK.EXE"
    An asterisk (*) is displayed beside the current format type.
    Note:
      If the above formats or valid partitions are not detected, the device
      driver identifies the MO disk as unformatted.

(2) File System
    The device driver supports FAT(File Allocation Table) file system.
    This system is used by DOS, Windows 3.x, Windows for Workgroup 3.11, 
    Windows 95, Windows NT, and OS/2.



5.  Details of the Device Driver : MODISKAP.SYS
===============================================
5.1  Syntax
-----------
Register the device driver in the CONFIG.SYS file as described below.
The description is not case-sensitive.  

DEVICE=(path)\MODISKAP.SYS  [/p] [/Ii] [/Rr]
or
DEVICEHIGH=(path)\MODISKAP.SYS  [/p] [Ii] [/Rr]

  /p  Pause option
  Pauses screen messages after the device driver has been initialized during
  the computer startup process.
  Press any key to continue the operation.  Specify this option to check the
  message displayed by the device driver.

  /Ii  Device number option
  Only the device connected to port i is mounted.
  Where i is defined as:
     1 = Primary Master
     2 = Primary Slave
     3 = Secondary Master
     4 = Secondary Slave
  If this option is not specified, all ports are scanned. 
  Therefore, this option need not be specified usually.  
  
  /Rr  Reserved drive option
  Specifies the number of logical drive letters (r = 1 to 10) for a single
  drive.  If this option is not specified, a single drive letter is reserved.


5.2  Drive Letter Assignment
----------------------------
(1) If the inserted disk contains more partitions than specified by the /R 
    option when the system is booted, as many drive letters as partitions are
    assigned to the MO disk drive.
    For example, if option /R2 is specified in the CONFIG.SYS file and the 
    computer is started with a three-partition disk, three drive letters are
    assigned to the MO disk drive.

(2) If a disk, containing more partitions than the number of drive letters
    assigned to the MO disk drive, is inserted after the system has booted,
    the driver can access only as many partitions as the number of assigned
    drive letters.
    For example, assume that two drive letters are assigned to the MO disk 
    drive.  If an MO disk with three partitions is inserted, the driver cannot
    access the third partition.

(3) If the disk inserted into the MO disk drive has fewer partitions than the
    number of drive letters assigned to the drive, an error only occurs if the
    driver attempts to access the additional drive letter.
    For example, assume that two drive letters (D: and E:) are assigned to the
    MO disk drive.
    If a single-partition disk is inserted, 
    the driver can access the disk using drive letter D:.
    Attempts to access the disk using drive letter E: will produce an error.
    In the case of an error, DOS displays 
    "Invalid disk type"
    and Windows 3.1(or WFW 3.11) displays
    "Drive E: does not exist."

(4) Last drive specification
    The last drive specification (LASTDRIVE=*) in the CONFIG.SYS file does not 
    affect the drive letter assignment in the MO disk drive.

(5) Drive letter for CD-ROM drive
    If this driver assigns a drive letter higher than the one specified by 
    LASTDRIVE=* (default is E:) in the CONFIG.SYS file, the CD-ROM drive cannot
    be accessed because no valid drive letter has been assigned to it.
    To enable access to the CD-ROM drive,
    specify a greater value for LASTDRIVE=.

6.  Smartdrv
============
The Smartdrv cache is turned OFF by default for MO disk drives, but it can be
turned ON.  When the Smartdrv write cache is turned ON for an MO disk drive, do 
not attempt to write data to a write-protected disk.  If you attempt to write
data to a write-protected disk while the Smartdrv write cache is ON, it may be
necessary to suspend the current job and reset the computer.
In that case, the current data will be lost.
