We will be more than glad to help you. In order to do so, we need to know the following:
1 - Is the OS installed on the SSD or HDD?
2 - How many drives are in this set up?
3 - What type of drive are they (SSD or HDD)?
4 - Is this a RAID arrangement? What type?
1) OS is installed on HDD
2) Right now it's real simple. 1 @ HDD and 1 @ (unplugged) SSD
3) See #2 - as basic as it gets right now
4) No RAID at this time. Just doing pure SSD acceleration at the moment in front of the HDD.
These are the requirements to enable cashe:
1 - The chipset must support Intel® Smart Response Technology
2 - A traditional primary hard drive.
3 - A secondary SSD drive.
4 - The SATA controller must be set to RAID mode (no arrays need to be configured).
5 - The Intel® Smart Response Technology must be installed. Chipset Software — Intel® Smart Response Technology User Guide
We hope this piece of information helped you.
Thanks for the reply but it doesn't answer my question - see the subject where is says "Windows 8.1 *already* installed"
#4 is where the problem starts. Windows is already installed and my AUS Z97 Pro MB is already setup for AHCI mode and not RAID. As such, when I change the mode to RAID, Windows fails to boot up. Put it back to AHCI mode and Windows boots up fine.
You've indicated the list of requirements in the order they occur for a green-field Windows not yet installed process. In your list, that happens between steps 4 and 5.
In my list, Windows was installed before step 4.
Question is is there some way to get Windows to boot up again when the motherboard mode is changed from AHCI to RAID ?
Apparently this is possible. It's just not readily apparently nor documented well from what I've found. I did a bunch of searching today and found this:
Very bottom of that post is a link to here:
Even though that is written for going from ATA to AHCI mode .. guess what .. the process works for Windows 8.1 installed in AHCI mode and post-install changing over to RAID mode.
I now have a SSD accelerated Windows 8.1 DIY machine
