Changing SSD access from IDE to AHCI on dual boot system

I have a dual boot system based on an Abit IP35 Pro motherboard with a Samsung 840 SSD partitioned C: Win XP Pro 32bit and D: Win 7 64bit Professional.
The original configuration was with a Seagate hard drive but this was failing and I transferred an image of the disk to the SSD using the enclosed copy of Ghost.
I have resolved the alignment issue on the SSD using Aomei partition assistant, but the original drive was set up as IDE rather than AHCI which Samsung Magician keeps prompting me to change . I know how to edit the registry in Win 7 to enable AHCI but as the system is dual boot which OS should I enable AHCI in first. Should I download and install the Intel drivers on Windows XP, then reboot into Win7 and carry out the registry edit and then restart and change the controller to AHCI in the bios?
Any help in the order to do this would be appreciated.

Both OS need to call up the same drivers. Either from 2 different places or from the same place. This gets hard to juggle and remember; so you need to be organised and patient. Me? I'd go crazy trying to manage two OS on the same machine. You can find on likes one sort of file system the other likes another. One likes one sort of internal communications protocols and the other likes something different again. This is what I'm finding in these forums. It makes me wonder why the need for 2 OS on the one PC? But i don't get out much lol.

Why do you want 2 OS on the same pc?

No no, not a driver issur. I understand. One drive is configured AHCI and one legacy. What you can do is: Run a re install on the Operating system that has to be legacy, but instead of re-installing, run fix, with the bios set at AHCI. That should do it.

Unfortunately some older legacy software will not run on Win7 especially 64bit so I need to keep XP running. I also have lots of video editing software installed on this OS which I either no longer have the installations for or cannot afford to upgrade to run on Win7

Many thanks
