This is a follow-up to THIS THREAD.
In the light of more information, I am making a second thread.
I have several of these Advantech PCs. Some are UNO-2174Gs (Sandy Bridge QM67 "Huron River" with Celeron 847E CPUs), one is a UNO-2184G (Sandy Bridge QM67 "Huron River" Core i7-2655LE).
I have not yet successfully gotten a 2174G to switch from IDE to AHCI/RAID (BSOD upon reboot) but I was able to get the 2184 to switch successfully. The 2174 and 2184 were both set to IDE in their BIOS from the factory, and all of them had their AHCI drivers (msahci, iastor, iastorv, etc) disabled (start set to '3' in the registry) from the factory image of Windows 7... but here's the difference:
The 2184 had iaStorA and iaStorF in the registry!!! From the factory!!!
To be clear: the 2174 and 2184 both BSOD if you just switch from IDE to RAID or AHCI, but the 2174 BSODs no matter what combination of msahci or iastor* drivers you enable in the registry. The 2184 has two more iastor drivers in the registry - A and F. When enabling these (start mode set to '0' in the registry), the computer successfully booted when set to RAID mode in the BIOS!
The 2174 PCs do NOT have the iaStorA or iaStorF driver, and I can't add it because the Intel RST drivers won't install unless they detect compatible hardware already in the system... and since Windows won't boot when the controller is in that mode, it's a catch-22!
How do I force the installation of iaStorA and iaStorF without a compatible AHCI controller present in the system (i.e. the storage controller is still in IDE emulation mode so Windows can boot)? The Add Hardware Wizard doesn't show anything when I point it at the "F6 floppy" folder of AHCI drivers.
I don't even know why the 2184 and 2174 have different factory images as the hardware is virtually identical - I'm considering imaging the 2184 on to the 2174s and just forcing a CD key change. It's really stupid.
