	Chessmaster 2000 is an excellent program with almost all the
features you could possibly want rolled into one package.  Its only flaw
is that it is copy-protected.  It is not an auto-booting disk, however,
and with a simple patch can be backed-up and/or placed on a hard disk.

1. Copy all the files to a formatted diskette or a hard drive.  Do not
bother copying the hidden file "priority.sw".  This file is located on
track 39 and is where the copy-protected sectors live.  Put your master
diskette in a safe place; you probably won't need it again.

2. Type "rename cm.exe cm<ENTER>"

3. Type "debug cm<ENTER>"

4. Type "u 741<ENTER>"  You should see the following:

XXXX:0741 50            PUSH	AX                                 
XXXX:0742 E8D744        CALL	4C1C                               
XXXX:0745 83C402        ADD	SP,+02                             
XXXX:0748 0BC0          OR	AX,AX                              
XXXX:074A 7407          JZ	0753                               

5. Type "a 741<ENTER>"

6. Type "jmp 74c<ENTER><ENTER>"

7. Type "w<ENTER>" and then "q<ENTER>"

8. Type "rename cm cm.exe<ENTER>"

9. That's it.  Enjoy.
