Installing the Professional Database on your hard disk

The Professional Database contains over 10.000 games and is delivered 
together with the Informant openings key (4th edition) on a number of 
disks. This is how you can merge them into one large database on your hard 
disk:

1. Make sure you have about 3 MBytes available on the hard disk.
2. Copy all files onto the hard disk, preferably into a separate directory 
   reserved for the Professional database.
3. Start ChessBase as described in the manual. Give 'DATABASE' as the name 
   of the database.
4. Start the Export file DATA2 (see manual). Import all games. Important: 
   use the simple "Import" function in the "Export" menu, not "Import &    
   assign" in "'Assign".
5. Start the Export file DATA3 and import all games. Start DATA4 and 
   import all games. (Atari users: import all games from DATA5 as well). 
   Important: do not change the order of imports (DATA2, DATA3, etc.).
6. The Professional Database is now installed. The games are already 
   classified in the Informant key so that you can use it without further 
   ado.
7. After you terminate the program you can delete the files DATA2 to DATA4 
   (or DATA5) from your hard disk, since they are now all contained in 
   DATABASE.

Note for Atari users who do not have a hard disk
The Professional Database was divided into five parts to enable you to 
copy each part together with the informant key (DATABASE.KEY and 
DATABASE.POS) onto one double sided disk. Remember that you must change 
the name of the key files to match the games files (e.g. DATA2.KEY and 
DATA2.POS) and then "Reassign all" in the "Assign" menu. In this way you 
can install five complete database on five separate disks.
