Bios Mods -The Best BIOS Update and Modification Source

Hiya~

Just recently got a new IdeaPad 320 with paycheck and would like a little help on changing the boot logo. I've done it for my Asus Desktop motherboard but I tried extracting the resources from the Bios update exe downloaded from the site but have had Zero luck with it so far. The files were in a .fd format and I have no idea how to find the logo and replace it...

I've done my research and even tried various tutorials such as this but it was of no help at all and couldn't assist me.. I'm willing to co-operate and assist anyone volunteering to help me out with this task and will even do it myself as long as I have some guidance and such..

I've read here that the BIOS are locked by the OEM and I have to unlock it or such? Can I have any more info for this Notebook/laptop? I've really got my undies in a twist with this.. 

Thanks in advance xoxo :*

Really? Nothing so far? Lenovo actually made something unmoddable..? I'm still willing to do it myself with some guidance ;~;
