[CentOS] Request advise regarding Driver for Intel Motherboard

Hello All

I made the mistake of assuming all Intel motherboards would be Linux
compatible out of the box and bought one without checking support
information. And now on initial install the Network is not
working....the Network port is not detected at all.

I have bought an Intel board DG41RQI
(http://www.intel.com/support/motherboards/desktop/DG41RQ/index.htm)
which does not support Linux Out of Box. I am using a Core 2 Duo E7200
64 bit processor.

I am installing CentOS 5.x XEN, minimal install for a XEN dom0. The
Intel Linux Support page links to this page here
http://forgeftp.novell.com/driver-process/pub/update/realtek/sle10sp2/common/i586/
and lists a lot of drivers. Can someone please advise me which ones I
need to install for my particular motherboard & processor type?

Also, will these drivers clash with yum updatation from CentOS repos?

Can someone please guide and if possible, comment on issues I will
face. Intend to install minimal xen dom0 install and couple of low
utilization servers and linux desktop. Also, would like to know if I
can install Windows XP on same desktop under XEN.

With best regards and thanks.
Sanjay.
