As described in the thread title, I want to change my SSD drives from IDE to AHCI. I have a new system as described with my signature. My operating system is Windows 7 Pro (64-bit) and I have the latest version (10) of Intel's Rapid Storage Technology (IRST). My two SSD drives (ADATA S599, 64 GB) that hold the OP system are configured as RAID 0, and show up under IRST. I have the latest firmware update (ver. 3.4.3) for my Adata drives. When the system boots, all drives, including my SSD drives, post as IDE drives. Oh, and all of them are installed on the Intel (ICH10R) SATA 3 GB/s ports. Now, I would like to switch these Intel ports from IDE to AHCI. Many have suggested this is a fairly easy fix:

However, before I proceed, I have several comments and questions: (1) In Regedit, the Start value for msahci is listed as 3, but the Start values for iastor and IastorV are listed as 0, (2) Now, I need to change the Start value of msahci to 0, right? (3) But what happens when I reboot the system after making this change? I cannot change to AHCI as the SATA drives are configured as RAID, and will not boot if I switch from RAID, (4) Will I need my Windows disk to install the AHCI drivers when rebooting my system?
