3. H/W SETUP Getting Started 3. HARDWARE SETUP 3.3 Getting Started IMPORTANT: Due to Pentium 4 CPU’s power consumption requirement, an ATX12V power supply is recommended for this motherboard. For typical system configurations, an ATX12V power supply that can supply at least 230W and at least 8.5A on the +12V lead is required. For heavily-loaded configurations, an ATX12V power supply that can supply at least 300W is required. Before using your computer, you must complete the following steps: • Ch

3. HARDWARE SETUP 3.4 Motherboard Settings WARNING! Computer motherboards and expansion cards contain very delicate Integrated Circuit (IC) chips. To protect them against damage from static electric- ity, you should follow some precautions whenever you work on your computer. 1. Unplug your computer when working on the inside. 2. Use a grounded wrist strap before handling computer components. If you do not have one, touch both of your hands to a safely grounded object or to a metal object, such a

3. HARDWARE SETUP 2) USB Device Wake Up (USBPWR) This allows you to disable or enable the USB device wake up function. Set this jumper to Enable if you wish to use your USB devices to wake up your computer. This feature requires an ATX 12V power supply that can supply at least 2A on the +5VSB lead. The default is set to Disable because not all computers have the appropriate ATX power supply. Your computer will not power ON if you set this to Enable and do not have the appropriate ATX power suppl

3. H/W SETUP Motherboard Settings 3. HARDWARE SETUP 3) CPU External Frequency Setting (SW1) This option tells the clock generator what frequency to send to the CPU, DRAM, AGP, and the PCI bus. This allows the selection of the CPU’s External fre- quency. IMPORTANT: 1. In JumperFree mode, all dip switches must be set to OFF. 2. When JumperFree mode is enabled, use BIOS setup in place of these switches (see CPU Speed in Advanced Menu in BIOS Setup). NOTE: Only selected switches are illustrated. For
