Thank you for your prompt response. The board which you suggested looks good for our purpose but i am stuck as i am not able to find the corresponding intel fsp. Would you mind pointing out the name of the said FSP. or Is there any other method / documents which provides the solution. I found the following document. " https://www.coreboot.org/Board:intel/d945gclf"; again it is the old link! I am a bit confused , as where is the new updated link? Also this link does not inform about any FSP ? Any suggestions would be appreciated. Sincerely, JunSal
