Bios Mods - The Best BIOS Update and Modification Source

I have an hp 3000mt with a core 2 duo e8400, I'm planning to upgrade to a core 2 quad q9300 but when I go to check for support, it is not supported by hp. Are there any existing bios that will make the cpu work even though hp don't have it on the supported list? 

Current BIOS already has support for Q9300.

Then why hp don't include the info on the product support page?

Ask them.

Do Load Defaults in BIOS after CPU exchange.

Are there any other thing I should do?

Delete all CPUs in Device Manager and reboot.

After uninstalling all the cpus, no more cpu in task mananger

Run msconfig. Press button Advanced options on current OS in Boot tab. E.g.

Uncheck Number of processors. Press OK.
Reboot and make new screenshot of main tab of CPU-Z.
