F1:Help Esc:Previous Menu :Select Item +/-:Change Values Enter:Select Sub-Menu F9:Setup Defaults F10:Save & Exit 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. ICH Delayed Transaction: Select [Enabled] will enable delayed transactions for internal register, FWH, and LPC interface accesses. USB Controller: Use this to enable or disable the use of USB controller. USB Device Legacy Support: Use this to enable or disable support to emulate legacy I/O devices such as mouse, keyboard,... etc. SDRAM CAS# Latency: This parameter controls the latency between the read command and the time the data available. CPU Thermal Throttling: Select [Enabled] will enable P4 thermal control circuit to keep CPU from overheated. DRAM Thermal Management: Select [Enabled] will reduce the temperature of North Bridge and DRAM. AGP/PCI Frequency: You may select among four sets of configuration options as the AGP/PCI frequency. The default value is [67.2MHz, 33.6MHz], and other configuration options are: [72.0MHz, 36.0MHz], [64.0MHz, 32.0MHz], [76.0MHz, 38.4MHz]. 21
