                =======================================

I. Description:
   ------------
   The NEMM.SYS is a standard MS-DOS device driver that uses the CS82212
   as its chipset.  It gives you the power of LIM 4.0 in the same
   manner as a standard EMS card (Above Board).


II. Installation and Usage:
    -----------------------
   Add a command line in the CONFIG.SYS file to install NEMM.SYS file.

               DEVICE = [d:] [path] NEMM.SYS [F:x] [P:y]

   Without any parameters after the above command line, the EMS driver
   will use the default hardware values of the configuration.

   You can use optional items listed below ( F or P ) to change
   the default values. Optional items include:

               F = page frame address (address of 64K window)
                   (EMS Base Address Register  bit 7-4)
                 x = 0  --> C000H,C400H,C800H,CC00H
                     1  --> C400H,C800H,CC00H,D000H
                     2  --> C800H,CC00H,D000H,D400H
                     3  --> CC00H,D000H,D400H,D800H
                     4  --> D000H,D400H,D800H,DC00H
                     5  --> D400H,D800H,DC00H,E000H
                     6  --> D800H,DC00H,E000H,E400H
                     7  --> DC00H,E000H,E400H,E800H
                     8  --> E000H,E400H,E800H,EC00H


               P = I/O port of the page register
                   (EMS Base Address Register  bit 0-3)
                 y = 0  --> 208H/209H
                     1  --> 218H/219H
                     2  --> 258H/259H
                     3  --> 268H/269H
                     4  --> 2A8H/2A9H
                     5  --> 2B8H/2B9H
                     6  --> 2E8H/2E9H



   The command line can be upper or lower case.


III. Samples :
     ---------
       1. DEVICE = NEMM.SYS  F:4  P:5

            PAGE FRAME = D000H,D400H,D800H,DC00H
            PAGE REGISTER = 2B8H


       2. DEVICE = NEMM.SYS  P:1 F:3

            PAGE REGISTER = 218H
            PAGE FRAME = CC00H,D000H,D400H,D800H


IV. Product files :
    ---------------
	There are two files in the directory :
      	(1) NEMM.SYS     - Neat EMS manager device driver program.
      	(2) README.TXT   - This documentation file.


V. Supporting hardware (mainboards):
   ---------------------------------
	Mainboards with CS82212 chipset.

** If you want to use EMS 4.0, you must use the BIOS setup program
   to enable EMS and select the EMS memory size as you want.
   Refer to your BIOS setup manual.
