AHCI.......confused.

Hi to all NG,

before reinstalled the operating system in the BIOS, I have changed the

configuration from SATA as (IDE) to SATA as (AHCI), because my hard disk is

SATA II.

I need to ask you (please): to make the HD work in AHCI mode, do I have

to install any other drive?

if the answer is yes... which drive and how?

in the BIOS, do I have to make other changes?

I hope you can help me, because I could not find the correct answer.

forgive my English and my "ignorance"

thanks in advance
