My Asus Z97-Pro (WiFi ac) have bios v2303:

 

 

So I load the new bios (all the more recent bioses anyway) on USA flash:

 

 

I picked up the latest one (v2702) and tried...

 

 

...to upload it, then I get "not a proper BIOS" message:

 

 

NONE of the bioses I tested (v2401, v2501, v2601 and v2702) worked. All I download directly from Asus site:

http://www.asus.com/cz/Motherboards/Z97PROWiFi_ac/HelpDesk_Download/

...so could SOMEBODY tell me, what is going on?!

 

 

 

Next thing - let's try the mainboard function of USB BIOS Flashback - I put into the proper port (page 2-14 "bottom port supports USB BIOS Flashback") USB drive with file in the root directory, renamed by the BRenamerl.exe utility to "Z97P.CAP")

 

After power up, I hold the BIOS_FLBK button for 3+ seconds and I expected to see 3 blinks of the LED and beggining of the flash proces, but ABSOLUTELY NOTHING HAPPEND.

 

 

 

The last attempt to flash bios update on Asus Z97-Pro (WiFi ac) was my attempt to boot from USB flash. Formated as DOS bootable device (or DrDOS) and in both attempts failed. Even afer disconnecting both SATA devices (HDD + DVD).

 

 

 

So the mainboard works, but it did not see the Samsung SM951 (MZ - HPV1280) M.2 128G SSD is not seen as device in bios or HDD prep programs like Mini Tool Partition Wizard Pro. Any help is need:

 

 

...perhaps it is just me, doing something wrong?

Ooops, my epic fail, lol...

 

Now I finally have the bios updated! I completely forget, that my mainboard is not "Asus Z97-PRO (WiFi ac)", but a "Asus Z97-PRO (WiFi ac)/USB 3.1" and that means, that I tried different BIOSes. Witch end up with the "impossibility to update" the bios.

 

Now I running at bios v2702, yet the M.2 SSD (Samsung SM951) is still "not present" in bios, or for HDD prep program (Mini Tool Partition Wizard Professional) or visible for Windows 7 install:
