Large hard drive upgrade on Predator 3610's boot drive? UEFI Bios support?

I have a Predator 3610 desktop, i7, win 7, 64 bit, but it has a very slow "eco" boot drive. I want to upgrade to a fast, 3-4 tb boot hard drive but have been warned that some Bios' won't recognize anything larger than 2tb's. From reading it looks like I need to have a UEFI Bios. Does anyone know off hand if the above computer would be able to use a 3 or 4 tb boot drive? How do I tell what kind of BIOS do I have (old style Bios or UEFI?)? I've read lots of posts but can't be certain if such an upgrade will work - it looks like win 7, 64 bit should be UEFI compatible, but I want to be sure. Again, I want to boot from this new drive (I've read how some system will read data but won't boot from such a large boot drive). Also, I've seen a good price on a large hard drive built for NAS use - will this work as a boot drive? Thanks!

That chipset had some issues.

h67 flaw <---Read there.

Looks like, as long as you plug the new drive into one of the 6gps sata-ports, you should be alright. The 3's are the ones that may give you trouble.

Edit: sorry, got a bit distracted there, will see what I can find on the bios.

Counldent find anything on your model, However.....

1.

Click on Start and then Run.
2.

In the text box in the Run window, type msinfo32 and click OK. This will open the System Information program.
3.

When System Information first opens, it defaults to the System Summary, a short list with some of the most important information about your computer system listed.
4.

On the right side of the program, locate the BIOS Version/Date entry.
5.

This field contains the BIOS version that is currently running on your motherboard. This field may also contain additional information such as the BIOS date, BIOS manufacturer, motherboard manufacturer and the motherboard model number.
