[K12OSN] Zotac Zbox realtec network driver missing in Centos5.5

[Barry R Cisna]

It may be worth noting there are a few variants of the Realtek gigE
nics. The r8169 that is supplied with ltsp/k12ltsp distro  will work
with most of the Realtek gigE cards/chipsets ,,r8169. It does work on a
couple of Acer laptops confirmed. 
But,,there are some bugs with this nic in some laptops/mobo's in regards
to WOL settings within the bios will cause some of these chips to not
work as expected or not at all.
Something to keep in mind with dealing with these nics.
