down, or reset your computer.
Startup/Shutdown
When you power on your computer, it looks for specific
files that contain the configuration information it needs to

CONFIG.SYS
This text file tells the computer where in memory to
load the operating system (MS-DOS), what device
drivers to install, and what memory management fea-
tures to activate.
For example, CONFIG.SYS directs the computer to
load the video drivers that identify your monitor type
and the mouse driver that activates the mouse. When
the system boots and accesses CONFIG.SYS, MS-DOS
is activated, device drivers are loaded, and memory
management features are executed.
