Changing to ACHI from RAID (Dell T5500)

Replacing 3x SAS disk RAID on a Perc6 controller, with a single SSD connected to the motherboard SATA ports, I needed to perform the following steps; otherwise I would get a BSOD on booting.

Run regedit
Edit the following keys so that the value is 0 instead of 3

(Windows 7)

(Windows 8)



Reboot, then change the BIOS settings in the from RAID to RAID/ACHI Autodetect
Make sure the SATA ports are enabled in the BIOS

Apply the BIOS settings, then reboot.
