Hey everyone!
It's been a little while since I've posted here but I have a question and I know all of you can help me out. So I know that AHCI is, at least I believe so, much better than IDE especially with SSD's because it allows for the use of TRIM. I am not 100% on that and I am not sure if simply switching from IDE to AHCI will take advantage of TRIM or not. I do believe though that SSDs run much better on AHCI as opposed to IDE. The only reason I even installed Windows the way I did (on IDE) was because I bought a OCZ Revodrive which became annoyingly complicated to install properly. It wasn't too bad once I finally was able to find a dedicated installation procedure but still a pain.
My question before I go on rambling too long is am I just able to simply switch from IDE to AHCI in Bios (I know I can but can I do that w/o any problems)? Will I mess up my HDD format? Lose files? Have to re-install everything to do this? etc, etc?
Hopefully you all understand what I am trying to ask.
Thanks in advance.
EDIT: While searching I was able to find this. Has anyone else tried this successfully?

A little guide:
I am receiving a lot of emails from users who bought a SSD drive, installed Windows 7 in IDE mode and then realize they need AHCI mode for faster SSD performance. Once you enable that in the BIOS during Windows 7 boot up, the OS will crash.
The common question is, is there a solve for this ?
To answer that question (and I do this safely with all Intel ICHR9/10 chipsets) there is a way to safely enable AHCI mode. Here we go:
1. Startup "Regedit
2. Open HKEY_LOCAL_MACHINE / SYSTEM / CurrentControlset / Services
3. Open msahci
4. In the right field left click on "start" and go to Modify
5. In the value Data field enter "0" and click "ok"
6. exit "Regedit"
7. Reboot Rig and enter BIOS (hold "Delete" key while Booting
In your BIOS select "Integrated Peripherals" and OnChip PATA/SATA Devices. Now change SATA Mode to AHCI from IDE.
You now boot into windows 7, the OS will recognize AHCI and install the devices. Now the system needs one more reboot and voilla .. enjoy the improved SSD performance.
We have not tested this on Vista though.
Update -- we tested and this tweak works in Vista 100% the same.
