3. HARDWARE SETUP 4) CPU External Frequency Setting (DSW Switches 1–4) This option tells the clock generator what frequency to send to the CPU, SDRAM, and the chipset. This allows the selection of the CPU’s External frequency. The CPU External Frequency multiplied by the Frequency Multiple equals the CPU’s Internal frequency (the advertised CPU speed). IMPORTANT: 1. To use this feature, check the JEN jumper settings: see Jumper/ JumperFree™ Mode (JEN) on the previous pages. DSW CPU 100MHz 103MHz

3. H/W SETUP Motherboard Settings 3. HARDWARE SETUP 5) Voltage Regulator Output Setting (PO_VID1 - 4) This jumpers allow you to manually adjust the CPUO core voltage. It is recommended to use CPU Default (all jumpers [3-4]) as the setting for CPU core voltage. CPU Default means that the Vcore is generated according to the CPU-VID design configuration. For each jumper setting, there are two voltage options, depending on the CPU used. NOTE: After PCB 1.04, the PO_VID jumpers simultaneously adjus
