Creating a Boot Diskette
To have enough memory for your games, you should make a
boot
diskette
before starting the DOS games. To make a boot diskette,
do the following:
1.
Turn on the computer and start DOS.
2.
Insert a blank diskette into the diskette drive.
3.
Type MAKEBOOT at the DOS prompt; then press Enter.
A boot diskette has started to be created. Before starting your
games, restart your computer with this boot diskette inserted
into the diskette drive.
Some sample files, such as CONFIG.SYS file, will be created on the
boot diskette. You might need to modify these files by referring to
the manuals that came with your game.

the game asks for this information, specify the default settings of the
Sound Blaster as follows:
