Running the Setup Program
The first time you use your computer, you need to run the
Setup program on the Reference diskette to define the
computer’s configuration. You may also need to run it again
later, if you change the configuration.
The Setup program automatically configures parts of your
system and lets you set (or change) the following for your
computer:
Display adapter type
Power-on password
Extended memory caching
Processor speed
Keyboard and speaker options
Real-time clock’s time and date
Hard disk drive configuration
Diskette drive type(s)
Serial and parallel port settings.
The configuration you define with Setup is stored in the
computer’s CMOS RAM, which is backed up by a battery.
Whenever you turn on the computer, it searches the CMOS
RAM for the correct installation information. If the computer
discovers a difference between the information in the CMOS
RAM and its actual configuration, it prompts you to run the
Setup program.
