Guys and gals (?), I would certaily use some help / advices, on how to make my M.2 SSD device visible in bios of my new Asus Z97-Pro (WiFi ac) mainboard.
I bought this one recently, to get a new -QUIET- build for gaming and apart from 1T WD HDD I get a 128G Samsung SM951 M.2 SSD drive. Upon inserting it into the mainboard:

...it is getting reasonably hot (especially the first chip - controller), so it should work, yet
it fail to show up in the Z97-Pro bios at all. So I cannot partition the SSD, nor start installing Win7 on it.
...
I tried to set the setting in Advanced / PCH Storage Configuration -
SATA Express(SATAEXPRESS) and M.2 Configuration to directly
M.2 instead of
Auto, but still no help. SATA is in AHCI mode.
Then I on youtube looked at this video:

Advanced / Onboard Devices Configuration and change the setting of
PCI Express X4_3 Slot (Black) Bandwitch from
Auto Mode to
M.2 Mode. However I did not find such option in my bios...
Also I noticed this thread:
http://rog.asus.com/forum/showthread.php?53091-Rampage-V-Extreme-M-2-Setup-And-Windows-Installation-......but this is, once again, about different mainboard - about Rampage V Extreme
😞So, a little help would go a long way there... Thanks!
PS. Looks like I'm not alone:
