When you first turn on your computer, the post screen will show up, and you will have to either press DEL or F1 or F2, to get into the BIOS, depending on the motherboard.
i got onto bios
i went into settings
i can only change fsb up to 133 166 and 200
i tried 200 wouldnt load windows unstable gave me 20 seconds till stops
i lowered it to 133 i overclocked it 400 mhz i might try going up once more
