BIOS speaker- 2 pins?

[kajabla]

I pulled the internal speaker out of an old iMac; it looks exactly like this:

My case didn't come with an internal speaker, and I'd like to know if I can use this one.
The motherboard is a gigabyte GA-880GMA-UD2H, and it has 4 speaker pins in its front-panel cluster. This speaker only has 2 - will it work? If so, which 2 should it be plugged into?

All right; I'll try wiring directly to test. Do you know if there's a way to get BIOS beeps besides restarting repeatedly?
