@noInk I think there was a thread where @Lost_N_BIOS said that GIGABYTE already provides the BIOS ready to flash out of their website.

I think all I needed to do was to rename the .F3D to .BIN file and it would work.

In any case I had a previous backup of the Engineering Sample BIOS and that seems to be in the .BIN format and the same issue is happening regardless of which BIOS I flash on the Chip.

Do I need to include anything into the BIOS before flashing? If so that might be the reason as to why the board can’t see the Chip there or react to it.

@hoyzon

Manufacturer usually doesn't provide UEFI flashable binary by third party hardware programmer. You need to use the manufacturer software to update.
Only once you download the chip content off the board you can flash the binary back without issue.
UEFI bios lack certain entry by design, some entry could be one-time programmed once the board is serialized other may require attestation to work other might auto-generate by request.
Anyway I don't know why your board doesn't boot with it's "know to work" bios.


Are you sure you are using the right chip to boot?



I see 2 chip, one socketed and one soldered.
Does nothing change by removing the one socketed ( open with care ) and selecting the soldered bios trough it's switch?
is the chip inside the socket aligned or was it ever inverted? do you know it's pin position?
Does the image come from the socketed? or the red marked?

Probably the B_BIOS is the BACKUP BIOS and M_BIOS is MASTER so be careful.
I have no clue if by switching something on the board will copy\delete or damage the content of B_BIOS
See in that direction something.
If you can read the content without damaging the board try to get the B_BIOS to M_BIOS

@noInk I see. So essentially I need to extract the BIOS off the chip and then re-flash the extracted content into the Chip?


In terms of the BIOS Switch itself, for some reason the Soldered BIOS or B_BIOS never seemed to work before. Only the M_BIOS/Socketed one.

@hoyzon

Essentially you need to restore it's know to work bios on the socketed chip.
If there an mark like an arrow on the board under the socket and a point on the chip those should match.
Also, check anyway the board location for hardware switch to select the chip but don't switch the switch.. yet.
Gather info about how to force the content of B_BIOS to M_BIOS. If the content within B_BIOS is intact maybe you can boot again.

Backup chip ^ pin one indicator will probably show same orientation as the one in the socket too. But this doesn't matter, you already know the wrong direction (HOT), so that only leaves the correct direction

Gigabyte BIOS are directly programmable from their website, they are.bin files and are not packaged in anything other than the zip you download. Programming them in work fine, I do it often in testing, with boards from as far back as P35, up until current models.
This works fine but you of course loose board specifics until you correct this, but that doesn't matter right now. And, in this situation the retail one may not work on this board at all programmed in or flashed in with Qflash/EFIFlash ect.
But, your originally dumped BIOS does not work back in their, so there is some other issue as I mentioned.

Soldered BIOS may not be compatible with your current CPU, it may only work on certain early ES etc, since this is an ES board.
It may be even earlier one than the backup you made, which as you expect should work once programmed back, thus some other issue.

Can be, the image just miss some stuff.
Usually most of the board would boot fine without those info.
If the board doesn't boot with an previously know to work image, there could be other issue to account.

Yes, I know stuff will be missing in stock BIOS download, but all are "bootable", having board specifics and NVRAM populated do not matter to boot on Gigabyte boards.
Right, that's what I've been saying too, something else is wrong here, since his previous backup wont cause any reaction to the power button.
