I have recently moved my Windows XP system disk from an older system to a newer system and it runs properly changing the driver a bit. The system disk I moved is Sata but it was accessed in IDE mode by the old system. On the new system, I want to access the disk in AHCI mode, but now I am using the Ide mode since XP will not boot this disk in AHCI mode. So, can anyone tell me how to replace the IDE drivers with AHCI drivers? Thanks.
