Yes, this ^^ I posted a reply for him as an edit above @Fernando

Hi @Fernando,

At least it let's me flash it without errors, just removing the official bios before clicking on the flash button and putting the modded file, but again when in bios I am not seeing any PATA devices, I can see my 970 in windows now though. Please see attached images of the process. Maximus V Formula I7 3770k

@Lost_N_BIOS
Thanks a lot for your answer. You did scare me a bit ;-). I don't want to brick my mainboard, so I will rethink the whole thing...

Maybe I will rather turn to some method of a boot manager on a bootable drive and the system on NMVe drive...

I have already tested the DUET/REFIND method successfully, but I would prefer the manager to be installed on a fixed SSD SATA Drive rather than on a USB stick - I hope this is possible. I will ask in the appropriate thread.

@Fernando @dustbrother - sorry for any confusion, I used GENE as source for the signed capsule, based on the mod BIOS dustbrother had originally named for USB Flashback (M5G), since he didn't mention model I simply went by the name he had used. The BIOS itself is whatever dustbrother uploaded in post #508.
I checked his uploaded BIOS just now, and he uploaded a modified Formula BIOS, so this is where the confusion came from, he has the wrong flashback name originally, which I didn't double check and just carried on using, assuming he had that part correct at least.
So that is two reasons why it wasn't USB Flashback flashing for him, incorrect USB Flashback name, and unsigned capsule.

M5F.CAP = Formula USB Flashback name
M5G.CAP = Gene USB Flashback name
Please name the file appropriately per whatever board you have dustbrother.
The BIOS is the one you uploaded, if you uploaded the incorrect modified BIOS for your model, you will need to make a new BIOS from the correct models base BIOS, and then upload and I will fix the signature.

To avoid further confusion, here is a new one in a properly named folder, and a proper USB Flashback name for use with Formula board.
This BIOS is modified by dustbrother, and is a ASUS MAXIMUS V Formula BIOS

Dustbrother - see my post a #509, it didn't flash your mod BIOS, it only acted like it and flashed the stock BIOS it already had in memory/temp, or flashed nothing and just acted like it flashed
The BIOS I posted above will flash via USB Flashback for you, if you can flash stock BIOS via USB Flashback with your current USB Stick you're trying to use.


@glorifyday - order CH341A ($2.50) + SOIC8 test clip with cable ($3.50) and then you don't have to worry about bricking any systems BIOS ever again, and you can easily put on any mod BIOS you want, any time
Let me know if you need linked examples of these on ebay.
