1. Instructions for DOS/Windows 3.1/3.11 users
==============================================

1.1. Installing LS120
---------------------

There are two ways you can install the LS120 driver:

1.1.1 If you want the driver to be loaded during system boot up, 
      type A:(or B:)\LS120\INSTALL.EXE

1.1.2 You can also load the driver from the command prompt by typing LS120 
      from A:(or B:).

Note: 1. In this case, you need to run LS120 whenever your system
	 is restarted.
      2. This option cannot be used in Windows 95/98 DOS sessions.
      3. If you get an error message saying that there are not enough
	 drive letters available, add the following line in CONFIG.SYS,
		LASTDRIVE=Z 
      4. You can assign a fixed drive letter for all the systems for your 
	 parallel port drive. For example type LS120 /L:G where you would
	 like to assign drive letter G to the parallel port drive.


1.2 LS120FMT application
------------------------

LS120FMT application has the following features:

1. Option to scan the parallel ports for the existence of an LS120 drive 
   and also report the type of Super IO card installed in the system.
2. Disk utilities to display the existing type of format and create 
   floppy formats for 720KB/1.44MB/120MB diskettes. For the maximum 
   compatibility across all operating systems such as DOS/Windows 3.x, 
   Windows 95/98, Windows NT and OS/2, floppy format is recommended.
3. Option to create a parallel port boot manager diskette in drive A. This
   diskette can be used to boot from the LS120 connected to the printer port.
4. Option to make the diskette in the LS120 drive bootable. For booting from 
   120 MB diskettes, make sure a fixed disk format has been created using 
   LS120FMT.EXE application before making it as bootable. Please refer to the 
   topic "Booting from external LS120 drive" for more information.
5. Option to set driver command line options.


1.3 Booting from external LS120 drive
-------------------------------------

Booting from the external LS120 is a convenient method of running your
legacy applications that may require an older version of OS (for e. g. 
Windows 3.1). If you use an LS120 diskette, you can easily put your 
application and the operating system on the diskette. Once this step is
accomplished, you can then use the following procedure to boot from the
LS120 drive.

1. Insert a blank formatted 1.44 MB disk in drive A and make it as a boot 
   manager diskette using "Utils" - "Create Boot Manager Diskette" menu 
   option of LS120FMT.EXE application.
2. Do this step only if you do not have a bootable LS120 diskette.
   Insert a blank formatted 1.44 MB diskette or a 120 MB diskette (if it has 
   the fixed disk format created using "Utils" - "Quick Format" menu option 
   of LS120FMT.EXE) in the external LS120 drive. Make this diskette as DOS 
   bootable diskette using "Utils" - "Make LS120 Bootable" menu option of 
   LS120FMT.
3. Set Boot sequence in CMOS to A, C.
4. When system starts up, boot manager menu is displayed. Press Ctl + Z
   (Control Key with letter Z) to boot from parallel port. The system will
	 boot into whatever the Operating System that resides on the diskette
	 you have in the LS120 device.

After you have booted through LS120, the LS120 drive takes over drive A if 
the diskette capacity is 1.44 MB or drive C if the diskette capacity is 
120 MB. 

If there are problems while running Windows 3.1 after booting from the parallel 
port, comment out the SMARTDRV.EXE line from autoexec.bat and then try running 
Windows 3.1.


1.4 Driver command line options
-------------------------------

Use the command line options ONLY if the driver is unable to detect the
hardware or if the driver exhibits a data reliability problem. The options 
can be set using the "Device" - "Driver Settings" menu option of LS120FMT.EXE.
The command line options cannot be changed if the driver line in CONFIG.SYS 
is commented out (with a "REM").

The command line options are:

1. Slow down Enhanced parallel port access
2. Turn off Burst Mode - This option slows down port access for 
   Uni-directional and Bi-directional parallel ports.
3. Force Port to behave as a Standard Parallel Port - This option will force 
   the driver to detect the parallel port as a uni-directional port which is 
   the slowest mode of operation.
4. Reduce Port access speed by [1-30] - This option slows down the port access
   by a slow factor number and is applicable for all parallel port types.

The Driver settings menu will be enabled ONLY if

- the driver line entry is present in CONFIG.SYS and
- the file INSFILES.INF is present in the directory where the LS120FMT.EXE
  is present.
