Y Pressing “Y” stores the selections made in the menus in CMOS – a special section of memory that stays on after you turn your system off. The next time you boot your computer, the BIOS configures your system according to the Setup selections stored in CMOS.
AR-B1841 User’s Guide Use this menu to load the BIOS default values that are factory settings for optimal performance system operations. While Award has designed the custom BIOS to maximize performance, the factory has the right to change these defaults to meet their needs. When you press on this item you get a confirmation dialog box with a message similar to: Load Optimized Defaults (Y/N) ? N Pressing ‘Y’ loads the default values that are factory settings for optimal performance system operations.
