Now that I am in front of my I-Op I can be more specific.
Don't target a mainboard!
Click on the radio button next to "Target Clock generator." Select "Target Clock generator."
Pick "IC-Works W156x" in the drop-down list. IC-Works and Cypress are now the same company.
Now, click on Option. Check the box next to "Using AOpen M/B"; this should automatically disable "ReadBack" and enable "Write Only PLL IC". Click OK.
Get FSB. This should tell you nothing but the CPU clock in MHz.
Choose "75(37.5)" with the slider, then click "Set FSB".
Congrats! Your stock IO is now running at 225.0 MHz. If it hung, go back through all the steps, choosing a different FSB. Keep trying until you find one that works.
The stock FSB is 66.8 MHz. This sets a 200.5 MHz CPU clock. With my method, most people should be able to get a 12.5% performance boost with no extra hardware and at no extra cost. Add a fan, and I wouldn't be suprised if you hit a 100 MHz FSB speed - which gives you a 300 MHz CPU!
I've created a profile for the I-Opener. I can't export it. The program requires a password for this. If someone can give me the password I can distribute a SoftFSB I-Opener plugin (Version 1?) to the world from my web page.
