Zitat von Lost_N_BIOS im Beitrag #225

@knowsthedose - You can use version 25 for insert, if you want to mod your boot logo etc. This one - https://github.com/LongSoft/UEFITool/releases/tag/0.25.0
And, after edit, compare side by side in NE version, make sure all "padding" comments in "Parser" tab match, none missing, and expand any volume you edited and make sure all paddings are same, none added or removed.

@knowsthedose - Those are two different logo, you only need to replace one. To see which is which, save body of RAW as jpeg and then look at it in photo tools. Then replace whichever you wanted to replace - Never mind, after checking your BIOS, I see both are same Usually one in small POST Logo not boot logo
On the padding stuff, I mean look at the "Parser" tab in UEFITool 5x, with before/after BIOS side-by-side, anything you see in Parser tab should match same/same (padding, non-UEFI, etc)
AND check top to bottom of the volume you edited in for any padding added or removed (there must not be any added or removed, only what was there originally)
None of this is the padding in your image, and you are not comparing side by side correctly, so be careful and do not flash yet until you've done this side-by-side check

You're welcome, let me know how it all goes! Yes, it must be due to that forum and this P, everyone gets model funky

I was able to load the bios you sent me thank you. It has so many options it's not funny. The laptop only goes into c10 state when the screen powers off, and c9 is inactive for the most part. At least c8 is active now and saves another 200-500mW. I don't know if I need to continue my hunt for a driver/service issue, or give up because panel self refresh is possibly not enabled by manufacturer. HWinfo shows that the monitor supports it, but because intel's panel doesn't show it isn't supported from a software/hardware level. I believe Fornando's nvme drivers may help, just don't like the idea of having unsigned drivers, and the possible pop ups.

The first few pages (old bios) can only be modified by software and no affect occurs when changing in bios and saving.
I was not confident enough to load my own bios, as I couldn't get the image bit rate to match. I was using ms paint I think it was mentioned to use paint net, which I couldn't install for some reason. It's no problem at all.

@knowsthedose - Please explain >> The first few pages (old bios) can only be modified by software and no affect occurs when changing in bios and saving. << What "few Pages" do you mean, and since you said "old BIOS", do you mean it was there before, and if yes, did it work then?
Your image may not work, generally you should keep same DPI and bit depth, unless you have a flash programmer to recover from brick during testing.

Hi everyone, there is my new problem and whole bios modding experience :)

After I read the first post carefully I decided to mod my bios myself and actually it was good thanks to great guideline of @Lost_N_BIOS :) After I flash my new modded bios with FTP I have directly go to BIOS from Windows by using advanced recovery settings and I was able to see all of my changes in bios and everything was perfect. After some time I decided to change nothing for now and I have restored default settings in Save & Exit menu and just after that open the XTU compability setting in BIOS for giving a shot but I did nothing different. Just restoring the default settings and enabling the XTU setting which I could not remember precisely the place of it. Then I exit from BIOS and I faced with just a black screen and open keyboard light. I think the cause of this problem might be my undervolt settings - 100.0mV - which is saved in Windows by XTU but I am not sure.

So, I have tried to replacing the CMOS battery and all of the discharging methods for solving the black screen but nothing worked and I ordered a CH341A programmer. Now my problem is that my FPT dump backup which is untouched is 6144 kB however, the file which is read from my BIOS chip with CH341A is nearly 8 mB. So, what can I do for flashing my FPT backup via CH341A to my BIOS chip?

My FTP Backup ------------------------------------> [[File:Old FTP Backup.zip]]
Bios file from my corrupted BIOS chip ----->[[File:Backup From Motherboard.zip]]

Thanks in advance!

@Necipking66 - Sorry to hear, and sorry this is short (out of time right now), but yes, possibly due to the XTU/under-volt you mentioned, or how you were doing what you were doing, not sure - that sounds weird and I'm not sure what you were describing doing
Here is fixed BIOS below, be sure you either google around for what software version is compatible with your BIOS chip ID (search google for here >> chip ID CH341A site:win-raid.com), or tell me your chip ID and I will advise you, otherwise write may fail.

Ohh, wait! Sorry, this dump you uploaded is only partial BIOS too! Either this system has two BIOS chips and you need to dump both and send to me, or whatever software or chip ID you used selected wrong size, or you picked wrong size or ID etc (BIOS should be 16MB once dumped from chip)
What model do you have?? And what is your BIOS chip ID, look in person, don't rely on software to tell you.

Looks like maybe you dumped wrong chip, unless this is just due to corrupted dump/wrong version/wrong ID - All this contains is multiple repeated vBIOS segments, so maybe you dumped the vBIOS and it's repeated to fill the selected dump size due to wrong software?

@Lost_N_BIOS - Thank you for your quick reply! So actually I realized that something is wrong with this backup from motherboard by examining it in Hex Editor. So, the chip which I have took a backup was WINBOND 25Q80EWNIG -it is the full name of it on the chip - and as far as I understood from the datasheet of this chip it is an 8mB chip. Now I am not quite sure about which 8 legged chip on my motherboard is my bios chip so I will take the backups of the several chips -which are marked with colored pen by manfacturer :) - and I will let you know in a few hours.

Actually the bricked laptop condition is very hard for me because my final exams - which will be online :/ - are coming in a few days. So I really need to this laptop in a short time. Why did I not just wait for the end of semester to customize this BIOS. Stupid myself

Thank you for your great effort . You are like my new Hero
---------------------------

Hi again everyone!
@Lost_N_BIOS you were right. The previous dump attempt was completely wrong due to choosing wrong chip and wrong program. After my several attempts to read the whole 8 legged chips on my motherboard both with Linux and Win 10 -with the help of the documents of the chips- I found the correct BIOS chip -which has common parts with my FPT backup in hex editor :)-. So the actual BIOS chip is Gigadevice GD25Q64 (B). I will add the new BIOS file which is dumped with CH341A and the my untouched and working FPT backup. I hope you can give me the correct file to flash this chip.

Note: @Lost_N_BIOS, you said that the bios file should be 16MB but I have tried all of the 8-legged chips on my motherboard and none of them was carrying a 16 MB file. Actually the biggest file I can get from the chips was just 8 MB BIOS chip.

New BIOS dumped with CH341A ----> [[File:New BIOS dumped with CH341A.zip]]
Working FTP Backup -------------------> [[File:Old FTP Backup.zip]]

Thank you in advance!

@Necipking66 - Sounds like you did it all OK, just that XTU/Voltage mistake I think

For GD25Q64 chip use software version 1.34 and GD25Q64 ID. What software and version did you use for the above dump? Be sure to use this version/ID to write, or it may fail to write properly (Do erase, blank check, open BIOS file, write/verify)
Sorry, I was initially looking at other BIOS when I said 16MB, then forgot to edit that back to 8MB once I realized what FPT dump you sent.

Here is your fixed BIOS I applied your edited unlock too, so now you should be back to square one before issue happened
I also unlocked the additional Keyboard Light Feature option at OG Advanced so you should now see two options there so more choices. I unsuppressed both and set both to User in AMIBCP too, since I was not sure which you could see currently

Be sure to program back in as I mentioned above, if you need 1.34 software version it's in this package

@Lost_N_BIOS - I really appreciate to your great effort to make this machine alive again :) It worked I believe you should change your nickname to God_of_BIOS :) I sincerely thank you for both sharing your valuable knowledge and fixing my device. Now I have an unlocked BIOS and working laptop

@Necipking66 You're very welcome, and I'm happy to be able to help you save your system and get BIOS fixed and all sorted out without further issues!
Ha, thanks, that would be a good user name But, due to how much I try to help, and can never keep up, I think my current name is actually more fitting
Anytime you need help with BIOS, let me know, I can probably help!

This is my new bios

thank！
------------------------

I also want to ask, can this setting be modified in bios?

------------------------

Hi there, I followed every step in this tutorial and got my Intel ME updated to the latest (12.0, Build 1551, Hot Fix 64
) first and then modified the bios, but when I try to flash the moded bios, got the error

Error 168: Hardware sequencing failed. Make sure that you have access to target flash area.
FPT Operation Failed.

need to mention I have a Machrevo Z2 Air, not the regular Z2, the Motherboard is displayed as MECHREVO GK5CP6X in hwinfo

original biosreg is attached in this post, can anyone help me to unlock the BIOS pls

@yaodao0yaodao - I can't download that file from google, says I have to sign in. Please upload to tinyupload.com or uploadfiles.io - thanks!
Then I can check about the Turbo Boost Power Max setting for you. Is your board bricked again? If yes See warning below

*** WARNING - To ANYONE with laptop and unlocked BIOS!!!! ***
DO NOT try to enable this graphics card or disable that card, switch cards etc. Otherwise you will end up with no display output (ie black screen) and no way to recover except by blind flash or with flash programmer.
You can change graphics related settings, like changing memory sizes, or core speeds etc, just don't try to disable one card or change which is main etc.
Additionally, be very careful when trying to undervolt CPU, you can leave BIOS unbootable due to CPU voltage too low (Sometimes even 0.05 is too much)

@37_ - Please dump FD and send to me >> FPTw.exe -desc -d FD.BIN
Then, reboot and try FPT steps 1-2 again, from spoiler below.

What do you mean you updated ME to latest, ME what, FW or driver, and why did you update anything ME related?

@Lost_N_BIOS ok I'll do it, need to check the steps carefully. Regarding ME update, I found my Battery is draining even it is shut down, (yes shut down, complete off, not hibernate) as soon as my PC is off AC Power, some google search indicates it is Intel ME related so I hoped update to the latest ME firmware will hopefully help to resolve the issue...

FD.bin

See my edit above @37_
Battery may be dying, if you can easily notice it draining when OFF, best to replace it. Intel ME FW or drivers are not active in OFF state, only system clock and possibly LAN module if you have Ethernet and Wake on LAN is enabled.
