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?)

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

Updated with red warning - thanks for the reminder @chinobino

Thank you for this guide, it works flawlessly

Thanks for reporting back @squeueue glad the guide was helpful for you!

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!
