A particularly useful batch file you may want to use is called
AUTOEXEC.BAT. Every time you turn on your computer,
MS-DOS looks for the
AUTOEXEC.BAT file and
automatically executes each of the commands.
When you install MS-DOS, it automatically creates an
AUTOEXEC.BAT file for you. To create or modify the
AUTOEXEC.BAT file, you can use the same programs that you
use to create any other batch file (COPY, EDLIN, 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 your AUTOEXEC.BAT file.
Changing the Processor Speed
Your computer’s processor can operate at two speeds: high and
low. High speed is 16 MHz and low speed simulates an 8 MHz
processor speed. 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.
Note
When your computer is operating at high speed, the TURBO
