Chipset Configuration: Advanced AMIBIOS SETUP UTILITY - VERSION 3.31a Chipset Configuration [ Setup Help ] AGP Mode AGP Aperture Size AGP Fast Write PCI Delay Transaction USB Controller USB Device Legacy Support DRAM CAS# Latency Hyper-Threading Technology DRAM Voltage AGP Voltage Auto 128MB Disabled Disabled Enabled Disabled Auto Auto Normal High to select AGP mode. F1:Help Esc:Previous Menu :Select Item +/-:Change Values Enter:Select Sub-Menu F9:Setup Defaults F10:Save & Exit AGP Mode: The default value of this feature is set to [Auto]. If you install an 8X-AGP card on this motherboard, you may select [Auto], [8X] or [4X] as the AGP mode. If the installed AGP card is a 4X-AGP card, then you may set the AGP mode as [Auto], [4X], [2X], or [1X]. AGP Aperture Size: It refers to a section of the PCI memory address range used for graphics memory. It is recommended to leave this field at the default value unless the installed AGP card's specifications requires other sizes. AGP Fast Write: This allows you to enable or disable the feature of AGP fast write protocol support. PCI Delay Transaction: Enable PCI Delay Transaction feature will free the PCI Bus when the CPU is accessing 8-bit ISA cards. Disable this feature when using ISA cards that are not PCI 2.1 compliant. USB Controller: Use this to enable or disable the use of USB controller. USB Device Legacy Support: Use this to enable or disable the support to emulate legacy I/O devices such as mouse, keyboard,... etc. DRAM CAS# Latency: This is used to adjust the means of memory accessing. Configuration options: [Auto], [2T], [2.5T], [3T]. Please note that not all the DDR DIMMs can support CAS latency=3T. Hyper-Threading Technology: To enable this feature, it requires a computer system with an Intel Pentium®4 processor that supports Hyper-Threading technology and an operating system that includes optimization for this technology, such as Microsoft® Windows® XP. Set to [Auto] if using Microsoft® Windows® XP, or Linux kernel version 2.4.18 or higher. This option will be hidden if the current CPU does not support Hyper-Threading technology. 27
