Asus P5K Deluxe Mother to recognize 3tb HD?

Hello, Hoping somebody knowledgeable enough here can assist me with this issue I have been confronted with.

I have an Asus P5k Deluxe Mother board and would like to use my 3tb hard drive that I just recently purchased as a slave (second) drive, not for boot drive.

The trouble I'm having is that my motherboard here is only registering about 800 gb of the drive. And without any coincidence so is my OS...

I was reading online about the possibility of having my motherboard be able to recognize the full drive capacity by using a modded bios. Is this at all possible?

This is the motherboard I have as noted below in the link;

I have updated to the latest bios release through Asus which unfortunately didn't resolve this issue. The latest bios release has been attached here.

Can this bios be modded to allow the motherboard to recognize the full drive?

Thanks for any help..

Richard S.
