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 is not 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 its actual hardware configuration, it prompts you to run SETUP. You see a message describing the error as well as the following prompt at the bottom of the screen:
Press <Fl> to run SETUP or <F2> to continueIf this happens, pressto run SETUP and correct the setting.
Another SETUP option displays information about your system board. This information provides a useful reference about jumper and DIP switch settings, SIMM configuration, and hot key combinations. See page
SETUP also lets you restore the default values for your configuration. This is useful if you have made changes but don’t want to keep them; you can restore all the default settings. See “Loading Default SETUP Values” on page
