Debian Network install disk doesn't find NIC

["Gary L. Roach" <gary719_list1@verizon.net>]

Hello everone;
I just got my new i5 based DP55kg system up and running. I inserted a 
newly minted installation disk and selected the gui installation. 
Everything worked fine till the program declared:

 No ethernet card detected but a firewire interface is present. Do you 
want to used the firewire interface?

There is a built in e1000e network interface on the board. When I 
selected NO to the firewire question and list of drivers popped up. One 
of the drivers was for e1000e. I selected this and the the program 
cycled back to the "No eaternet card" message.

I have a driver disk for the motherboard but it looks like it's strictly 
for windows.

Any suggestions
