I have a laptop that is set to ATA and I need to install an external sSATA DVD Rom. How can I change it to ACHI without reimaging the laptop?

If your bios has seperate controllers for your internal drives and the esata port, you should be able to turn on the esata port and set it to sata/ahci then install the sata/ahci drivers.

Unlike vista and win7 which have native sata/ahci drivers, XP does not. because of this, there is no simple registry hack to switch from one to the other. If you only have one sata controller, I beleive your only option is to reinstall. Use the F6 option during installation to load in the sata/ahci drivers.
