To unprotect Chessmaster 3000, you must have a exact duplicate of the originals
(using CopyIIPc, Teledisk, etc), Diskcopy will not work.  This patch was
used on the following file:
	install.exe	48290	11-13-91	12:00a

On your copied disk:

1)  You need to change the attribute of install.exe. from Read-Only.
    Using MS-DOS 5.0 and assuming disk 1 of Chessmaster 3000 is
    in drive B:
	attrib b:install.exe -R

2)  Do a search for the following bytes in install.exe: (Using Norton Editor,
    Debug, or your favorite editor)
	91 05 40 E7 80
    Replace with:
	91 05 60 E7 80

3)  Do a search for the following bytes in install.exe:
	4C 8D 54 07 E2
    Replace with:
	4C 8D 74 07 E2

4)  Change the attribute of install.exe back to Read-Only.
	attrib b:install.exe +R

That's all.  You can now install the game using this new disk.  I believe
the reason diskcopy does not work is because of the Volume Label.  It is 
probably possible for someone to fix install so it doesn't look at the
Volume, but I have spent too long on this already.  If someone absolutely
HAS to have that fixed, I can be reached on Rustie & Edie's BBS
