Need BIOS P4S266-VX SIS650

the computer model is a: Sony Vaio PCV RX-752

with a SIS650 motherboard P4S266-VX




i know its outdated because every time i boot it up it says error with BIOS update



i tried a BIOS update from Sony on their support page,
http://esupport.sony.com/US/perl/s [...] 79&os_id=7
but it was old, back in 2002 (thats like when i bought the system xD) so that didn't do anything and i still get the errors




before some guy tells me to use google or search...
i have spent at least 2 weeks googling
i need this BIOS because i upgraded my CPU from the built in 2ghz to a 2.5ghz (SL6PN 2.50 GHz N/A 1 400 MHz 0.13 micron D1 512 KB 478 pin N/A) and added 1gb of ram along with a new GeForce 7600 GS. Yet, the CPU speed doesnt feel any different.



I used this program to check my system for drivers and BIOS updates
but it wants to charge me $30 for the link to the BIOS.

That is my last resort


help me out here gentlemen!
