AUTOEXEC.BAT
PURPOSE:
The autoexec.bat file is a batch file that performs
any set of commands you would normally give when you
start up your computer.
NOTE:
Unless you have an installed clock in your computer, it
would be a good idea to include the "time" and "date"
commands in your autoexec.bat file. By doing this,
every time that you boot up your computer, it will
prompt you for the time and date. Therefore, the time
and date for the directory on your disk is kept current.
EXAMPLES:
A simple autoexec.bat file:
date
time
prompt=$p$g
dir
In this sample autoexec.bat file, which is a simple
batch file, the "date" and "time" commands ask you
to set the date and time each time you start DOS on
your computer. The command "prompt=$p$g" tells DOS
to display the default drive and directory, followed
by a greater than sign (>), as the DOS prompt. This
prompt helps you to remember what drive and directory
you are currently working in. The "dir" command
displays the default directory of the disk in the
default drive whenever you start up your computer.
CONFIG.SYS
Purpose:
Each time you start up DOS on your computer, it
automatically searches for the file called config.sys
on your system disk. The config.sys file contains
special commands that let you set up, or configure,
DOS for use with devices or application programs.
EXAMPLE:
Your config.sys should contain the following two
commands. However, it is ok if it contains more than
these two commands:
buffers=20
files=20
NOTE:
The command buffers=20 sets the number of blocks
of memory, or buffers, that DOS uses to store data.
If you have a large directory system, you might
want to increase the buffers number setting, for
example, buffers=40.
The second command in the config.sys file is
files=20. This command sets the amount of files
that DOS can have open at the same time. If you
don't set a value for files in your config.sys,
DOS assumes a value of 8, which isn't enough open
files for a large program such as a spreadsheet.
Since programs such as databases and spreadsheets
need several open files while they are running, so
it is important to set a value for files.
