I couldnt find this topic posted anywhere so am posting the link to the guide here. there is a pin on the pentium-m socket on the 915 mainboard of the laptop that needs to be grounded in order to increase the fsb to 533mhz essentially overclocking the cpu. this works on any 400mhz fsb pentium-m cpu wid i915 chipset. you cant mod in an 855 chipset socket coz it supports only 400mhz fsb. this mod essentially tells the mobo that the cpu utilizes 533mhz fsb tho the multiplier is locked. but the effective speed increases. i am not aware of such a mod for 400mhz fsb P4 configs. anyway this mod is useless for me coz the cpu in my laptop is already 533mhz plus its a P4. but i am interested to see you hardware junkies do the mod! i am eagerly waiting for this mod to taste success. here is the link..... http://www.notebookforums.com/showthread.php?t=80879 imagine getting 2.13ghz P-m out of a 1.8ghz one!!
