echo * INSTALL will create a subdirectory named MAXELL at the root of your hard
echo * drive, then it will copy all the files from your copy of 688 ATTACK SUB
echo * to the MAXELL directory on your hard disk.
echo * Only hard drives C: or D: are allowed.

echo * You must supply the letter for your hard drive.
echo * For example, if you want to copy to drive C:,
echo * type:
echo *              INSTALL C:
echo *   
echo * You can also specify floppy drive A: or B: as the drive containing your
echo * Maxell Preview disk.  Install will assume you are using drive A: unless you
echo * specify drive B:.  Only drive A: or B: are allowed. For example,
echo * if you want to install to hard drive D: from floppy drive B: type:
echo *  
echo *              INSTALL B: TO D:

echo * Don't forget to type the 'TO' if you are using this second method...
