[REQUEST] Unlocking Vaio PhoenixBIOS R174J3

Hi all. I have a Sony Vaio VGN-FE31HR laptop with a crippled BIOS which I'd like to tweak to verify RAM amount, set speed and timings (it uses i945PM chipset that should support up to 2x2 GB @ 667 MHz instead of the current 2x512 MB @ 533 MHz).
The link to the BIOS update is here.
