Appendix: Advanced BIOS Setup This section will introduce you the following BIOS Setup menus: "Advanced," "Security," "Power," "Boot," and "Exit." 1. Advanced BIOS Setup Menu Spread Spectrum: This field should always be "Disabled" for better system stability. CPU Host Frequency: [Auto]: The motherboard detects the jumper setup and sets the CPU host frequency automatically. [Manual]: This allows user to set CPU host frequency manually. However, this is not recommended unless user thoroughly knows the feature. Wrong setup may cause problems during operation. SDRAM Frequency: [Auto]: The motherboard detects the memory module(s) inserted and automatically assigns appropriate frequency. [Other values]: This allows user to select the value as operating frequency. Chipset Configuration: AGP Aperture Size: It refers to a section of the PCI memory address range used for graphics memory. We recommend that you leave this field at the default value unless your AGP card requires other sizes. OnBoard VGA Share Memory: This allows you to select the size of share memory for onboard VGA. Onboard VGA will get better resolution if larger size of share memory is selected. Please do not select [None] if AGP or PCI graphics card is not inserted. USB Controller: Use this to enable or disable the use of USB controller. 20
