This chapter tells you how to use the following procedures to enhance the operation of your computer:
0Using AUTOEXEC.BAT and other batch files
0Changing the processor speed
0Using expanded memory beyond 1MB
0 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.
