[. . . ] 1. Please read the users guide before proceeding with your installations. (This means unplug the power cord in the power outlet) Failure to do so will damage your memory module. They can go in only one way, and should fit completely in the socket without sticking out. If you have a Pentium 4 motherboard, you need to use an ATX12V power supply (power supply for Pentium 4 system) is required for the system to operate normally. [. . . ] The available CPU Ratio you can select will depends on your CPU ID. CPU Clock Ratio 8X~50X 45 BIOS Setup Utility SY-P4VGA 3-3. 1 DRAM Clock/Drive Control Caution: Change these settings only if you are already familiar with the Chipset. The [DRAM Clock/Drive Control] option changes the values of the chipset registers. These registers control the system options in the computer.

The [AGP & P2P Bridge Control] option changes the values of the chipset registers. These registers control the system options in the computer. Phoenix ­ Award BIOS CMOS Setup Utility AGP & P2P Bridge Control AGP Aperture Size AGP Mode AGP Driving Control x AGP Driving Value AGP Fast Write AGP Master 1 WS Write AGP Master 1 WS Read 64M 4X Auto DA Disabled Disabled Disabled Item Help Menu Level :Move Enter:Select +/-/PU/PD:Value F10:Save ESC:Exit F1:General Help F5:Previous Values F6:Fail-Safe Defaults F7: Optimized Defaults After you have completed the changes, press [Esc] and follow the instructions on your screen to save your settings or exit without saving. AGP & P2P Bridge Control Setting AGP Aperture 64M Size 32M 128M 256M Description Note Select the size of Accelerated Graphics Default Port (AGP) aperture. The aperture is a portion of the system memory dedicated for graphics memory address space (for when your VGA card runs out of memory). Host cycles that hit the aperture range are forwarded to the memory without any translation. Default 48 AGP Mode 1X 2X 4X BIOS Setup Utility SY-P4VGA Description Note AGP & P2P Bridge Control (Continue) Setting AGP Driving Control Auto Manual This item allows you to adjust the AGP Default driving force. This field is recommended to set in Auto for avoiding any error in your system. AGP Driving Value AGP Fast Write Min=0000 This item allows you to adjust the AGP ~ driving force. Max=00FF Disabled Enabled The VIA chipset will use fast write to Default AGP if this item is enabled. Default When Enabled, writes to the AGP(Accelerated Graphics Port) are executed with one wait states. Default When Enabled, read to the AGP (Accelerated Graphics Port) are executed with one wait states. AGP Master 1 Disabled WS Write Enabled AGP Master 1 Disabled WS Read Enabled 49 BIOS Setup Utility SY-P4VGA 3-3. 3 CPU & PCI Bus Control Caution: Change these settings only if you are already familiar with the Chipset. The [CPU & PCI Bus Control] option changes the values of the chipset registers. These registers control the system options in the computer. Phoenix ­ Award BIOS CMOS Setup Utility CPU & PCI Bus Control CPU to PCI Write Buffer PCI Master 0 WS Write PCI Delay Transaction Enabled Enabled Disabled Item Help Menu Level :Move Enter:Select +/-/PU/PD:Value F10:Save ESC:Exit F1:General Help F5:Previous Values F6:Fail-Safe Defaults F7: Optimized Defaults After you have completed the changes, press [Esc] and follow the instructions on your screen to save your settings or exit without saving. CPU & PCI Bus Control Setting CPU to PCI Write Buffer Disabled Enabled Description Enabled the CPU to PCI Write Buffer. Note Default PCI Master 0 Disabled WS Write Enabled PCI Delay Transaction Disabled Enabled This item allows you to enabled/disabled the PCI post write. Default The chipset has an embedded 32-bit Default posted write buffer to support delay transactions cycles. [. . . ] Install/ re-install the VGA driver. After wake-up from Suspend to RAM or Standby mode, the screen has no display but I can hear the hard disk operating (For External AGP card). Check your VGA card's manufacturer for a driver and VGA BIOS update, make sure the VGA card supports the Suspend to Ram function. Audio Issue How can I disable the on-board Audio?Go to "Integrated Peripherals\VIA Onchip PCI Device" in the BIOS setup, then set the "AC97 Audio" to disabled. Check if the speaker wire is connected to the line out connector in the M/B. [. . . ]
