Modded bios needed for hp z600

Hi all.

I'm looking to install an SSD for a boot drive. Currently this bios doesn't allow this. I would also like to have a little go at OCing the 2x x5650 I have in. Please can someone help with either modding  the bios or directing me to a modded bios 

Current bios is 
786G4 v03.61

Thanks for any and all help
