[CentOS] Adding third party driver at installation time.

Hi,

    I have a PCIe  storage device. My driver registers this device as a
block device in linux. My block device is working fine under linux.

    Following are the steps which I used for Centos installation on my
storage device:

    1)  During Centos installation time and before scanning of my storage
device, I loaded the driver from command line(By pressing Ctrl + Alt + F2)
from USB disk.
    2)  Post loading of drivers, the installation proceeded successfully on
my storage device.


    Query:

    1) How to add my driver as part of installed initrd image at the
installation time itself.[because root file system also installed on same
device]


Waiting for positive reply


Thanks & Regards,
Sateesh
