Program : S137xf4.com for S1372 IDE Controller Card)

Description : The s137xf4.com program is a Floppy Disk Device Driver
	      which allows you to configure your system to operate with up
	      to four floppy disk drives.  s137xf4.com is a user loadable
	      device driver which is loaded from the DOS command line prompt
	      or may be included in your autoexec.bat file.


1. If you are adding the third floppy drive to your system, you need to add

   DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:#

   in your config.sys. The parameters for the /F switch are as follow.

   0 for 160/180K or 320/360K
   1 for 1.2 MB
   2 for 720K
   7 for 1.44 MB
   9 for 2.88 MB

   So if your third floppy is a 1.44MB, then you would need to add
   DEVICE=C:\DOS\DRIVER.SYS /d:2 /f:7 in your config.sys file. Note that
   the driver.sys file comes with your DOS operating system.

3. If you are adding 2 floppy dirves to the secondary floppy channel, you
   need to add two lines to the config.sys file.

   DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:#   <-- this is for the 3rd floppy
   DEVICE=C:\DOS\DRIVER.SYS /D:3 /F:#   <-- this is for the 4th floppy

   You need to put the correct /F:# parameters for the floppy. Please
   refer to step 2 for more detail.

4. In your AUTOEXEC.BAT file, you need to add the following statement.

   S137XF4.COM W X Y Z

   w              Defines physical drive 0 (A:)

   x              Defines physical drive 1 (B:)

   y              Defines physical drive 2 (letter assigned by DOS)

   z              Defines physical drive 3 (letter assigned by DOS)

   w,x,y,z:  0 = no drive installed.
	     1 = 5.25" 360KB FDD.
	     2 = 5.25" 1.2MB FDD.
	     3 = 3.5"  720K FDD.
	     4 = 3.5" 1.44MB FDD.
	     5 = 3.5" 2.88MB FDD 

Example 1: If your system has 2 1.44MB floppy drives on the primary channel
	   and you want to hook up a 1.2MB floppy drive as the third drive.

In the CONFIG.SYS file you would add

	DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:1

In the AUTOEXEC.BAT file, you would add

	S137XF4.COM 4 4 2 0

The first 4 = 1.44MB
The second 4 = 1.44MB
The 2 represent 1.2MB
The 0 represent no floppy drive


Example 2: If your system has 2 1.44MB floppy drives on the primary channel
	   and you want to hook up a 1.44MB floppy drive as the third drive
	   and a 1.2MB as the fourth floppy drive.

In the CONFIG.SYS file you would add

	DEVICE=C:\DOS\DRIVER.SYS /D:2 /F:7
	DEVICE=C:\DOS\DRIVER.SYS /D:3 /F:1

In the AUTOEXEC.BAT file, you would add

	S137XF4.COM 4 4 4 2

The first  4 = 1.44MB
The second 4 = 1.44MB
The third  4 = 1.44MB
The 2 represent 1.2MB
