When you install MS-DOS, it creates an AUTOEXEC.BAT file
for you. To modify the file or create another one, you can use

the COPY or EDLIN command, or a word processing program
that can save a file as a text-only file. However, be sure to name
the file AUTOEXEC.BAT and store it in the root directory of

the hard disk or diskette from which you load MS-DOS.

See your MS-DOS Reference Manual for more information
about creating and using batch files.

Your computer’s processor can operate at two speeds: high and

low. High speed is 12 MHz, 1ow is 6 MHz. On high, the
computer can access memory faster than on low. Your processor

is set to operate at high speed unless you change the speed to

low or set the speed to change automatically.

You should use high speed for almost everything you do since

your programs will work faster. However, certain application

programs have specific timing requirements for diskette access

and can run only at the slower speed. See your software manual

to determine if this is the case.
