	main memory:	  490Kb of conventional memory to load program
			+  90Kb of conventional or UMB memory for VGA  		
			+ 130Kb of conventional or UMB memory for SVGA  		
			  (12Kb for sound and music is included above)
	ems:		2.2 Mbytes for VGA
	ems:		2.5 Mbytes for the High Speed SVGA & VESA drivers
	ems:		3   Mbytes for the Universal VESA driver


SUPER VGA DRIVERS
=================

After you have installed the OPERATION OVERLORD program disk set you will be
able to run the game in standard VGA mode.


You can then run SVGATEST. This program will attempt to set up an SVGA library
for your graphics card. If it is successful, then a high resolution
version of the title screen will be displayed. 

This indicates that you will be able to run OPERATION OVERLORD in high
resolution. At this stage you should install the SVGA graphics disk set.


We have SVGA drivers, High Speed VESA drivers and a Universal VESA driver.
The Universal driver should work on most cards but is slower than the other 
two options. Please run SVGATEST to decide which driver to use.

At the beginning of SVGATEST a list including the following chipsets 
will be displayed:

		Cirrus
		ET4000
		Trident
		#9 GXE
		ATI Mach 32
		
		

There are a number of manufacturers' brand names. In the following list, brand
names are matched with their driver:

		Hercules Dynamite	ET4000
		Genoa 8500VL		Cirrus
		Genoa 3989VL-12		ET4000
		Trident 8900		Trident
		Trident 9000		Trident
		Cirrus Logic GD-54xx	Cirrus
		Older Diamond Stealth	Vision
		Newer Diamond Stealth	ET4000

If you don't know which chipset you have, then select "Technical Information" in
the SVGATEST.

The following cards have been tested and work with the High Speed VESA driver:

		Cirrus Logic GD-54xx
		ET3000
		ET4000
		Trident
		#9 GXE
		Older Diamond Stealth
		Newer Diamond Stealth
		ATI Mach 32


The following cards have been tested and work with the Universal VESA driver:

		some S3 cards
		Pegasus
		Paradise

The following cards have been tested and do not work with the supplied 
VESA drivers:

		Orchid Fahrenheit S3

Please contact Virgin Helpline for the latest information on these drivers.


NOTES ON UNIVERSAL VESA OPTION (LOW SPEED)
==========================================

You must make ONE of the following edits to your C:\CONFIG.SYS file,
depending on the memory management software you are using:

On DOS versions before DOS 5 on the line starting DEVICE=C:\DOS\EMM386.SYS:
	Add the parameter:		 i=A000-AFFF

On DOS versions 5 and after on the line starting DEVICE=C:\DOS\EMM386.SYS:
	Find, and remove, the word:	 RAM
	And add the parameter:		 i=A000-AFFF

For Quarterdeck QEMM 386, on the line starting DEVICE=C:\QEMM\QEMM386.SYS:
	Add the parameter: 	 	 VREMS

        -If you do not have a monochrome monitor you can avoid rerunning 
         OPTIMISE by also adding the following parameter:
                                         RAM=B000-B7FF

For 386 MAX, on the line starting DEVICE=C:\386MAX\386MAX.SYS:
	Add the parameter: 	 	 i=A000-AFFF


After the "DOS 5 and after" edit some software won't work until the edit is
reversed. You may wish to make a bootable floppy especially for Overlord:

	FORMAT A: /S
	copy c:\config.sys a:
	copy c:\autoexec.bat a:

And perform the edit described above on A:\CONFIG.SYS

You will also have to change any lines starting DEVICE=\ to DEVICE=C:\
and any lines starting DEVICEHIGH=\ to DEVICEHIGH=C:\



ERROR MESSAGES
==============


1	ERROR: NotExist		Last file access:libs640.400\SGA_BITZ.bin


	This means that the SVGA driver has not been configured. Try running
	svgatest.
