Hi Ninad,
Finally I have a C2d E6300 and intel dg965ry mobo with 2 100gb SATA hdd. After assembling this I came to know that the dg965ry is not supported by the linux kernel. I have to wait for a new release of the kernel to be included in some distro.
Any other pointers to this problem are welcome I virtualization a temporary solution..
Check out the wiki page I have created on this issue at http://db.glug-bom.org/wiki/index.php/Linux_on_DG965RY_HOWTO
Regards, Rajesh
