Product description:

   This product is a collection of programs, which are installed in the
   C:\MGA\SETUP sub-directory.

Setup program:

   We strongly recommend that you run this program, as it will let
   you "optimize" your board/monitor configuration.

   SETUP uses the file MGA.MON as input, and saves your monitor choice in a 
   file called MGA.INF.

   Known bug : If there is no existing MGA.INF when this utility is invoked,
               it will return the PAL resolution as being available when
               in fact it is not ... please do not select this resolution.        

Monitor file:

   The mga.mon file provides generic monitor support and should cover
   most monitors. Some specific monitors are also included for Hitachi,
   NEC, Super VGA (max.35 KHz Horizontal), and 8514 monitors.

VESA driver:

   The MGAVESA driver supports VESA Super VGA Extensions version 1.2 and VESA
   Display Power Management Signaling (DPMS) version 1.0.

   The installation program for the Setup and Utilities can add the MGAVESA
   driver to your AUTOEXEC.BAT file automatically if you choose to do so.

   a) SVGA:

   The SVGA supported modes are:

   Mode   Resolution  Colors

   100h   640 X 400   256 colors
   101h   640 X 480   256 colors
   102h   800 X 600    16 colors
   103h   800 X 600   256 colors
   104h  1024 X 768    16 colors (interlaced)
   105h  1024 X 768   256 colors (interlaced)

   The SVGA modes use MGA's on-board VGA and cannot be used if the VGA is 
   disabled.

   b) DPMS

   The MGAVESA driver must be loaded in order to use DPMS under DOS.

   The DPMS supported modes are SUSPEND and OFF.
   The STANDBY mode is NOT supported by the MGA hardware.

   The MGA windows drivers have built in support for DPMS and thus do
   not require MGAVESA to be installed. A DPMS screen-saver is also
   provided by our windows drivers.
   See the Windows driver readme file for more details.

RAMBIOS.SYS:

   The RAMBIOS.SYS program puts the MGA's VGA BIOS in shadow RAM. For all
   AT, VL, and MCA MGA products, BIOS shadowing is MANDATORY for 
   single-screen operation. 

   Since RAMBIOS takes up 32K bytes of memory, it may be desirable to load it 
   "high" using a memory manager.

   There are two alternatives to using RAMBIOS.SYS. The first method uses your
   computer system's ability to shadow a VGA BIOS. If your system supports 
   this capability, it is usually accomplished through the system's 
   configuration program. There are certain instances where this method may 
   not work. The second method is to use a memory manager to shadow the BIOS.

   If MGA is run in a dual-screen mode, the MGA's on-board VGA is disabled
   and video BIOS shadowing is therefore not required.

SETVGA.EXE
   
   This is a VGA enhancement utility. The default setting is
   c:\mga\setup\setvga -m2. If this default causes problems with your 
   VGA applications, please try c:\mga\setup\setvga -m1 and remove this
   line from your autoexec.bat.
