When you finish using the Setup program, select the Exit option from the main menu. The program displays a list of the current settings you just made. Check the list before placing the settings in CMOS RAM. Below the list you see this menu:
m Change settings mExit without saving ** EXIT AND SAVE **
If any setting is incorrect, press Enter. The main menu is displayed again, and you can correct the setting.
If you did not make any changes, or if you want to cancel the changes you made, you can return to the OPERATION MENU or the MS-DOS prompt without re-booting the computer. Press 1 to highlight Exit without saving, and press Enter.
When the settings are correct, press 2 to highlight ** EXIT AND SAVE **, and press Enter. If you only changed the real-time clock, the MS-DOS prompt reappears. Otherwise, the program resets the computer using the new configuration.
If the computer displays a Setup error message during the power-on self test, run Setup again and check all your settings.
Setting the Real-time Clock
Your computer automatically keeps track of the time and date using a real-time clock. Because the clock is backed up by a battery, it keeps track of the time and date even while the computer is turned off.
The MS-DOS TIME and DATE commands, as well as many software packages, display the time and date held in the clock, but they cannot make permanent changes to the time and date settings.
Use the Real-time clock option if you need to change the time and date permanently. For example, you may need to change the clock to accommodate seasonal adjustments, such as daylight saving time. Your computer automatically adjusts for leap years. Note that even though MS-DOS and your applications programs may use a different format, the real-time clock uses a 24-hour time format to store the time.
