[Guide] Manual AMI UEFI BIOS Modding

@machineman :
Welcome at Win-RAID Forum!

I am sorry, but we don’t have the required time to check BIOSes, which have been modded by the users. I totally understand, that you want to minimize the risks of a failure, before you flash a modded BIOS, but we cannot overtake the responsability for a work , which has been done by someone else.

I don’t know the answer, but I really doubt, that this issue can be solved by a simple BIOS modification.

This is an Intel LAN Option ROM module. It will only be needed by the system, when you are going to start your computer by using the "Wake-on-LAN" option.

Another think. If i flash the bios with the modded one can revert changes with asus bios flashback.

Best Regards

@machineman :
You only have to use the USB Flashback BIOS flashing method, if you want to flash a modded BIOS into the BIOS chip of your ASUS mainboard.
If you are not satisfied with the result, you can reflash the original BIOS, which has been designed for your mainboard, by using the "normal" BIOS flash procedure (USB Flashback is not required in this case).

that will revert CPU microcode update wright.

Yes.

Can i insert this _BootAgentCL_15B8.lom file in bios or i should use another tool to reflash network card.

It depends on the manufacturer and model of your Ethernet Controller. What means "this"? I do not see any link or attachment.

If you are using an add-on card, it doesn’t make sense to insert the related module into the mainboard BIOS.

The network card is Intel® I219V on ASUS Maximus VIII Ranger motherboard. I will attach the file later because it’s on my home PC. I hope this helps.

Is it an Ethernet card (usually PCIe inserted) - as you have written - or just an on-board Ethernet adapter?
What is the reason why you want to insert this special Intel LAN Option ROM module into your mainboard BIOS?

It’s an on-board Ethernet adapter. I create this file with UBU tool. I want to reflash the ethernet card option rom.

The UBU tool doesn’t create any file. It just updates several modules of an UEFI BIOS, but no Option ROM module of AMI Aptio V BIOSes…

What means "reflash"? Isn’t there any Intel Ethernet Option ROM within your BIOS?
If you should mean "update" (instead of "reflash"), what do you expect from an update of an Ethernet Option ROM? Is it just a demand to have the latest of everything?
Just for your information: An Ethernet Option ROM or EFI LAN module will only be needed and used by your system, if you want to start-up your computer by LAN command (= "Wake-on-LAN" feature). Do you use or intend to use this feature?

Yes i want to use WOL feature.

And it doesn’t work with your current BIOS?

super thx

At first step you should look into the Event Checker to find out the reason for your issue.

ME Version in bios show N/A and usb flashback doesn’t help. Intel onboard lan and IME devide are missing in device manager.
