enable vBIOS? It’s always enabled, it’s part of the BIOS. I am not aware of any way to edit variables for vBIOS settings in grub/shell. Only way I know to change vBIOS settings is a vBIOS editing tool or Intel BMP if Intel vBIOS
IFR output is just text of the BIOS settings, if you’re talking about from the setup module per this guide. You can’t “Read or flash” vBIOS if it’s part of the actual BIOS when you’re not talking about a PCIE Graphics card, only edit the entire BIOS, editing the vBIOS module and then reflash
Here is the vBIOS included in the BIOS you sent, these are for onboard graphics via the CPU, vBIOS can be edited and updated with Intel BMP program, but likely no settings you are interested in - [Guide] Transfer of specific Intel VBIOS settings by using Intels BMP tool

I see this you might need to change? You can adjust these in grub, or by editing the setup module/IFR

thank you for reply, My problem is that I can’t read or write the vBIOS ( that why I tried to edit it in the main BIOS ) I just ask if there any chance to unlock it so I can flash edit and flash only vBIOS
my laptop has 1 Intel and 1 AMD GPU, I tried to edit the AMD one but the tools from the most popular Guide fail right when I tried to backup my vBIOS.
No, you cannot only flash vBIOS, well you can for AMD if it’s separate card like you mentioned.
For the Intel CPU vBIOS, you can extract the vBIOS and modify some settings (Probably none you want to edit) with Intel BMP I linked for you previously.
Aside from that, settings you would actually want to edit for vBIOS (Intel/CPU GFX) are shown above, those can be edited via grub or by editing setup module.
As for the AMD GPU, you can dump it’s vBIOS by selecting that GPU at bottom of GPU-z and then dump the vBIOS. Then send me that file, I’ll check and let you know what if any tools I can find that will let you modify it.
If you cannot select AMD GPU in GPU-z, then it’s not enabled, and you’ll need to adjust some of the setitngs below

sorry for reply late, yes GPU-z can’t get my AMD vBIOS out, I get some error like " bios reading not enable" or sort of,
so setup_var 0x7BA 0x4 and setup_var 0xFFFF 0x1 is the fix for that right ?
No, those are graphics related settings, enabling certain ways to use graphics, nothing like what you mention.
Show me image of GPU-z without error, then another with error on screen too
here is the image of GPU-z, hope you can help.

The VBIOS is located inside the main UEFI Firmware. See below and attached archive.

thank you, is this the vBIOS in my bios file ?
what exactly should I do to mod and flash in new bios ?
and there are 4 of them, why is that ?
Thanks @lordkag really appreciate the dump txt for GUID locations too thanks!! - There are 4 due to different configurations likely use this BIOS.
@cuongvfc - I will modify for you, give me some time, little busy right now, thanks!
oh please take all the time you need. and thanks @lordkag for helping as well
edit: I actually want to OC it since I get so much stuttering playing game, heat issues is from my CPU and I managed to fix that, my GPU is around 70-75C when playing games.
@cuongvfc - I see Intel Management mentioned in this BIOS, do you know what ME FW is used in there, or none? If none, which I suspect, do you know if there is a way to check on your end either in BIOS or software if Intel Bootguard is enabled?
If it’s enabled then you can’t use a modified BIOS. Normally I could have you check this with matching MEInfoWin to your ME FW version, but I don’t see it so I can’t point you at the right package to check with.
And I can’t check with FITc for the same reason, so we need to find another way to check, unless you have already flashed a mod BIOS and it was OK?
Because when you modify this BIOS you get the expected warning due to bootguard/ACM >> checkProtectedRanges: AMI protected range [121000h:484C00h] hash mismatch, opened image may refuse to boot
I would not advise flashing this BIOS unless you have hardware flash programmer in hand and are ready to recover, with a verified and valid backup already
I could not find any tools to edit Atom or 530 vBIOS, sorry. This has updated EFI GOP images added to the oroms with GOP Updater, so they are now EFI/Legacy oroms, I am also not certain if that should be the update method used? @lordkag
Still does not show in UBU, probably incorrect way to do this update? Be warned, and ready for recovery if you flash this BIOS (Sorry, maybe lordkag can better advise me on how they should be updated?)
Example image of one of the modules before/after update
thanks for your reply, if in that case, I’ll just leave it as it is. It gonna be a mess if I break it. but seriously thank you very much
Order a CH341A programmer ($2.50 on ebay) and SOIC8 test clip cable ($3.50 on ebay), then it’s no problem to test and see the outcome! Plus, once you have those, you will then be able to recover any board BIOS, or flash any modified BIOS even if system tells you no 
Thank you for this guide, it works flawlessly
hello,my board is asus a88xm-plus,and i add nvme module to the bios.
1.i try it but i can’t find the “bios lock”.
2. i try to read the bios after using the other way of “afu /gan”,but it didn’t have the nvme module in the bios.
3.how can i do ^^^^^^^^^^^^
AMD based board do not have this setting @gloobox - you will have to try this method, and use that AFUWin attached to the thread - https://linustechtips.com/main/topic/592…r-motherboards/
If that does not work, try AI Suite method mentioned here - [Guide] How to flash a modded AMI UEFI BIOS
If still no luck, you may need to purchase CH341A flash programmer ($2.50 on ebay, or 2-3x more if you need quicker/locally) - https://www.ebay.com/itm/201316582787
Also, get one of these for easier chip removal - https://www.ebay.com/itm/123167465408
all failed~~~
i have to buy a ch341a
anyway thanks for helping!!!
@gloobox - Sorry, but yes that is what many with A88X board ended up doing, I tried to look around for you yesterday for some success stories but all ended in fail except flash programmer.
At least you will then have programmer to save you from bad flash in the future!
