Unknown SAS Controller in Win 2008 for S2600GZ

[idata]

I have a new Intel R2312GZ4GCSAS server system with the optional RES2SV240 RAID expander card installed.This system comes with the RMS25CB080 hardware RAID module pre-installed.

When installing Windows 2008 R2 with SP1, after installing all chipset, NIC, RAID, and related drivers, I am still seeing an unknown device in Windows Device Manager. It is listed as "SAS Controller" See screenshot here http://screencast.com/t/GnyUbkCmu5 http://screencast.com/t/GnyUbkCmu5

Anyone know which driver I need to install for this?

It could be the onboard SW RAID. Based on your BIOS settings, you could try one the following drivers:

You can also check in the BIOS and disable any onboard controllers not in use. That will usually get rid of the extra controller listed in Device Manager.
