Running the SETUP Program
You need to run SETUP the first time you use your computer.
Even if your system was configured for you, you may still need
to set the date and time, and if your system came unconfigured,
you need to define how it is set up. (You also may need to run
SETUP again later if you change your configuration.)
SETUP is stored in the computer’s ROM BIOS, so you can run it
any time. SETUP lets you verify or change the following:
Current date and time
Type of diskette drive(s) and hard disk drive(s)
System memory
Type of video display adapter
Keyboard options
Processor speed
Shadow options
Processor chip features.
The configuration information is stored in an area of memory
called CMOS RAM. This memory is backed up by a battery, so
it is not erased when you turn off or reset the computer.
Starting the SETUP Program
You can run SETUP whenever you see the operating system
command prompt, such as:
C:\>
or A:\>
To start SETUP, hold down Ctrl and Alt, then press S.
