Chapter 4
Enhancing System Operations
This chapter tells you how to use the following procedures to
enhance the operation of your computer:
Using AUTOEXEC.BAT and other batch files
Changing the processor speed
Using expanded memory beyond
1MB
Using the VGA utilities.
Using AUTOEXEC.BAT and Other Batch Files
As you get used to using MS-DOS and your application
programs, you may find that there are commands you need to
run frequently. You can automate the execution of these
commands by listing them in a special file called a “batch” file.
When you type the name of the batch file and press
Enter,
MS-DOS executes the commands in the file just as if you had
typed each command from the keyboard.
If you have a word processing program that can save a file as a
text-only file (sometimes called an ASCII file), you can use it to
create a batch file. You can also use the MS-DOS COPY or
EDLIN command to create the file.
One batch file that you may find particularly useful 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.
