Have you been brave enough to try and reset the bus-to-multipier ratio by directly tying new lines to the CFG_PLL pins ? I have halfway into a project to replace the 100 MHZ CPU with a faster part (a 180, to be precise). I plan on swapping it out with the old one and lifing the PLL pins up and running my own lines to set the ratio (I am hoping to run at 166 MHz). Of course, when I say halfway, that means I have lifted the old CPU (easy), but havnt gotten the nerve to try and translplant the new one (hard).. : ) Mad Dog ---------- Duo/2400 List, The friendliest place on the Net!
