from ICH use 15 mils trace
Place Cap. as Close as possible to ICH2
ICH2 DECOUPLING CAPACITORS
ICH2 PCI / HUB LINK / CPU / LAN / INTERRUPT SIGNALS
Place one 0.1U/0.01U pair in each corner and
2 on opposite sides close to ICH2 if it fit
This resistor less than 0.5"
Distribute near the 1.8V
power pin of the ICH2
Distribute near the VCC1_8SB
Power pin of the ICH2
Trace width use 15 mils and 15mils space
