i have been digging around and the closest i can find is if you set jumper "jb1" to 3&5 shorted and 2&4 shorted you might be able to run at 400mhz. but i don,t know for sure because i can't get a good pix or docs on the motherboard.
see if it has a jumper for 60/66 buss speed.
it may auto detect and you will be stuck at 6*60 instead of 6*66.
also your bios should not recognize the chip properly and you would ne to tweek the settings manually to get maximum performance.
lastly i am not sure what voltage you will be sennding to the cpu you want 2.2 core 3.4 i/o but 2.4 and 3.5 will work.
you can look here to find all the info that i did.
