[REQUEST] Network Driver for 6100 series 6

I have been using DriverPacks for some time at my job; I found a computer that is not supported though. Work bought some computers that were on sell that have Vista on them but at work we only use 2000, so I had to reformat. The problem is that the Ethernet controller was not installed like it should have been. I can not even find the right driver that I need online.

Here is the computers they bought...

I was told that it had this MOBO in them...but I think that is wrong because this MOBO is for notebooks.

If this could be updated into the next update that would be great, but if someone knows the link to where I can DL the network driver so I can get this up and running, even better.
