SoftFSB orso to set higher bus speed?

[Thijssss]

I got some older version of the ASUS P2B and the max I can set my FSB is 133Mhz.. ; I found SoftSFB after a short search on the net (most links are dead it seems) but that neither enables me to set it to 140 or 150Mhz.. I know the BX chipset can do it; is there some other way or is my mainboard limited by some other chips?
