1. Preface
==========
Thank you for using FUJITSU SCSI magneto-optical (MO) disk drive. 


2. Overview
===========
The device driver, MODSIK2.SYS, in this package allows you to use SCSI 
MO drives in the DOS environment.
This device driver supports 2048byte/sector MO disk(640MB, 1.3GB)using 
with SCSI MO drives.

This Drivers and Formatter support MO drives shown below.
    FUJITSU M251*
    FUJITSU MC*3***SS
    FUJITSU MD*3***SS


3.Contents of the package
=========================
MODISK2.SYS    Device driver
MODISK2.TXT    Explanations of the device driver
FJFDISK.EXE    Formatter
FJFDISK.TXT    Explanations of the formatter
INSTALL.EXE    Installer
INSTALL.MSG    This file is used by the installer.
README.TXT     Explanations of the installer


4.Notes
=======
1.Use the latest ASPI manager. Contact the manufacturer of your 
   SCSI host adapter card for their latest driver.

2.Do not use this device driver with other device drivers 
  which controls SCSI MO disk.

3.This device driver supports only Logical Unit Number 0 (LUN 0).

4.Utility program which rewrites the boot sector cannot be used with
  2kB/sector disk(640MB , 1.3GB).

5.If execute FDISK for 2KB/sector disk, the disk capacity is quarter of 
  actual capacity.

6.When using MO drive with Always IN-2000 SCSI board, note the following:
    If the setup of IRQ on mother board and that of SCSI board are not 
    coincide, the ASPI manager does not work properly.
    For detailed information, refer to manuals of PC and SCSI board.

7.Cannot execute the built-in formatting command of DOS (FORMAT command) 
  for 2KB/sector disk.

8.MO disks can be formatted by the built-in formatting command of 
  DOS (FORMAT command). 
  Two different type disks cannot be formatted successively.
  In order to format two or more disks using FORMAT, terminate FORMAT 
  command each time and re-start FORMAT command with the next disk inserted.

9.By default, the Smartdrv write cache is OFF for MO drives.
  It can be set to ON.
  When the Smartdrv write cache is ON for MO drives, NEVER attempt to 
  write data to a write-protected disk.


5. Installation
===============
The source of installation need not be a floppy disk.
For example, you can make a sub-directory on your hard disk, and copy all the 
necessary files to that sub-directory before installation.
The following description assumes that the installer is in floppy disk drive A:.

 1) Set A:\ as the current drive.
 2) Type "INSTALL" at the DOS prompt and press the [Enter] key.
 3) Follow the on-screen instructions.
 4) When the installation is complete, re-start your computer.

 The installer automatically performs the following:
 a) Copies "MODISK2.SYS, MODISK2.TXT, FJFDISK.EXE, FJFDISK.TXT"
   to the C:\SCSIMO directory (Default).
 b) Adds the following line to the last line of C:\CONFIG.SYS.
    DEVICE=C:\SCSIMO\MODISK2.SYS


6. Uninstallation
=================
To uninstall the device driver manually, perform steps a) - b) below 
by yourself.  Then, re-start the computer.

 a) Deletes "MODISK2.SYS, MODISK2.TXT, FJFDISK.EXE, FJFDISK.TXT"
   from the C:\SCSIMO directory (Default).
 b) Deletes the following line to the line of C:\CONFIG.SYS.
    DEVICE=C:\SCSIMO\MODISK2.SYS


7. Trouble-Shooting
===================
This section helps you if you encounter problems when using SCSI-MO drive.
There are following troubles which cause problem:

  - Hardware trouble
  - Software troubles
  - MO disk troubles


7.1 Hardware Trouble
--------------------
(1) Is MO drive turned on?

(2) Is SCSI cable firmly connected to MO drive?

(3) Is SCSI cable firmly connected to SCSI board in your computer?

(4) Is terminator setting/connection correct ? 

(5) Is total length of SCSI cable too long?

(6) Aren't SCSI IDs doubly registered? 
    The SCSI ID of each SCSI device must be unique.

(7) Is SCSI board firmly connected to your computer?


7.2 Software Trouble
-------------------
(1) Is the ASPI manager loaded?

(2) Dose the ASPI manager correctly recognize the MO drive?

(3) Is this device driver registered after the ASPI manager in CONFIG.SYS file?

(4) Isn't the MO drive controlled by the BIOS on SCSI board?
    This device driver does not read/write MO disk in the drive which is 
    controlled by the BIOS on the SCSI board.


If all items mentioned above are OK, the device driver should be loaded in memory.


7.3 MO disk trouble
-------------------
(1) Is the disk physically formatted ?

    In order to know whether the disk is physically formatted, run FJFDISK.
    If the disk is not physically formatted, FJFDISK displays message,
    "Low-level format is needed".
    Then continue to execute low-level format using FJFDISK.

(2) Is the disk logically formatted ?

    In order to know whether the disk is logically formatted, run FJFDISK.
    FJFDISK shows the mark "*" in front of the format type in which the 
    disk is formatted now.
    If the disk is not logically formatted, no "*" will appear.
    Then continue to execute logical format using FJFDISK.
