That's just a list of variants on a single northbridge.
This particular machine actually has the Intel P45 but you don't need to know that.
Running the one with the installer is a little easier so just download it and execute it to install it.
Or if you don't like installers and declining included software then just download the zip file and unzip it.
When they give you a list of names it means that they're all variants on the same design and will use the same chipset driver.
The southbridge for this computer is an Intel 82801JR which is also known as the ICH10R. For example, a chipset which shows up as Intel i875P may also be referred to as an Intel 875 or Intel 875P.
You just install the chipset driver and it automatically takes care of setting up individual drivers for each of the devices in the chips.
But a few motherboards use northbridge and southbridge chips from different manufacturers in which case you need to load the drivers for each chip separately.
If you're having any kind of stability problems with your motherboard then it's a good idea to install the latest chipset drivers.
AGP slots are especially susceptible to flakiness caused by old chipset drivers.
In the exceedingly rare cases where CPU-Z doesn't work you can try Sandra Lite. CPU-Z uses the term chipset rather than northbridge.
