CentOS - May 2010 - Installing a CentOS based distro with Raid driver - Citrix XenServer

Hi everyone,
I'm trying to install a XenServer on a server (ref:S5000PAL) 
http://www.intel.com/products/server/motherboards/s5000pal/s5000pal-overview.htm

The installation failed because of lack of Raid driver, I found this out 
because I tried to install XenServer
without raid and it worked great.
I tried so many drivers, I don't know what to do
I tried also this trick :

with this :

driver, but it didn't work (I use the SATA Raid controler not the SAS, 
so it seems that I have to find the good driver for ESB2 but I'm not 
sure and it uses megasr driver)
Anyone as a clue ?
PS : I posted on Citrix forum but nobody's answering, if someone here 
has a clue I'm greatful to him

May be a "Fake RAID" rather than true hardware raid.  See
