Chapter 2 BIOS Setup BIOS (Basic Input and Output System) records hardware parameters of the system in the CMOS on the motherboard. Its major functions include conducting the Power-On Self-Test (POST) during system startup, saving system parameters and loading operating system, etc. BIOS includes a BIOS Setup program that allows the user to modify basic system configuration settings or to activate certain system features.
2-2 The Main Menu On the main menu of the BIOS Setup program, press arrow keys to move among the items and press to accept or enter a sub-menu. Or you can use your mouse to select the item you want. (Sample BIOS Version: F1a) Setup Menus Enter Q-Flash Select Default Language Help Function Keys Configuration Items Current Settings BIOS Setup Menus M.I.T. Use this menu to configure the clock, frequency, and voltages of your CPU and memory, etc.
2-3 M.I.T. Whether the system will work stably with the overclock/overvoltage settings you made is dependent on your overall system configurations. Incorrectly doing overclock/overvoltage may result in damage to CPU, chipset, or memory and reduce the useful life of these components. This page is for advanced users only and we recommend you not to alter the default settings to prevent system instability or other unexpected results. (Inadequately altering the settings may result in system's failure to boot.
`` M.I.T. Current Status This screen provides information on CPU/memory frequencies/parameters. `` Advanced Frequency Settings && CPU/PCIe Base Clock Allows you to manually set the CPU base clock and PCIe bus frequency in 0.01 MHz increments.
