The configuration you define through SETUP is stored in a special area of memory called CMOS RAM. This memory is backed up by a battery, so it will not be erased when you turn off or reset the computer. Whenever you reboot the computer, it checks the settings, and if it discovers a difference between the information in the CMOS RAM and your system’s configuration, it prompts you to run SETUP. You see a message such as the following:
CMOS memory size mismatch
RUN SETUP UTILITY
Press <Fl> to RESUME
Press Fl to run SETUP and correct the setting.
Starting the SETUP Program
TO start the SETUP program, make sure there is no diskette in the diskette drive; then turn on your computer. (If the computer is already on, press the RESET button on the front panel to reset it.)
After the computer completes its self test, you see the following prompt:
Press <Del> to start SETUP
As soon as you see this message, press the Del key. If you do not press Del within five seconds, the computer starts loading the operating system and you will not be able to run SETUP. If this happens, reset the computer and try again.
You see the following options:
Start operating system
Run SETUP
