Looks like CPU External Frequency Selection (Dip Switches 6-10) for a P4 2.26 Ghz is:
DSW 6-on 7-off 8-on 9-on 10-off.
For the CPU Frequency Multiple Setting (Dip Switches 1-4):
DSW 1-off 2-on 3-off 4-off.
Your frequency multiplier is 17. (17X133=2.26) Just look at the chart and follow the diagram for your multiplier.
This is Frequency Multiple setting for the 533Mhz FSB.
Settings for 400Mhz FSB are included in the link.
JEN must be set to jumper mode.
If you want to try overclocking your machine you can use settings for higher multiplier. Remember you'll be OC'ing the FSB so the CPU, AGP and memory will all run at higher speed. You'll void your warranties if you decide to OC but where's the fun in playing it safe?
