HARDWARE SETUP 4) CPU Type Frequency Setting (PALO_FREQ) This jumper setting accomodates the difference between the internal frequency between standard and new AMD CPUs. If changing from one type of CPU to another, the jumper caps must be adjusted. The factory default setting, [2-3], is for standard Athlon/Duron CPUs. The Palomino processor will only function on this motherboard after the jumpers are adjusted to [1-2]. PALO_FREQ 1 2 3 1 2 3 FID0 FID0 FID1
