How to extract and edit a Lenovo Phoenix TDK Bios

I don`t know how to do that sort of modding. Maybe someone at PHOENIX BIOS EXTRACT

can help.

post the bios here, not on other sites..

For insyde use BIOSUtilities from platomav https://github.com/platomav/BIOSUtilities , requires some setup, you feed it the Insyde .exe (sometimes downloaded from Lenovo, sometimes you have to use innoextract first)
Or one of those 2 Insyde extractors to extract the .fd file https://github.com/vaginessa/InsydeH2O-extractor-2
https://github.com/LongSoft/InsydeIm...actor/releases
If you get a 24MB file (exactly 25,165,824 bytes), the BIOS may need to be split into 8MB + 16MB, the motherboard has 2 BIOS chips close together in this case
Open the 24MB file with UEFITool NE, then if it's a Intel Image with Descriptor, ME and BIOS regions it may need to be split, the first part from 0-7FFFFF, the rest from 800000-17FFFFF is the second part

It isn`t a phoenix TDK bios, it`s Insyde. Search for the word BIOSIMG in the FD file, the line just below that is the start offset at 1E6BB0. Select block, the start offset as 1E6BB0, 800000 as the length (800000 is 8MB) ,copy that to a new file. The line below that 8MB offset is the start of the 16MB bios, set the first offset, enter 1000000 as length ,copy to a new file , you now have the 8 & 16MB virgin bios.

I just unpacked an Insyde bios with innoextract and got a 24MB bin file instead of an fd file. Do I use the same procedure? I can see the word BIOSIMG in the file.

Easier method:
Extract the downloaded .exe from Lenovo website with innoextract
https://github.com/dscharrer/innoextract
If you only have the first .exe and nothing else (like the BIOS on 1st post), follow the step on 1st post to extract it

5PCN20WW.exe /ext

Note: On newer BIOSes you'll get to the bios.cap after extracting with innoextract

Once you get to the bios.cap, open it with UEFITool NE A72
https://github.com/LongSoft/UEFITool/releases

Expand the UEFI capsule -> UEFI image -> (GUID) => (another GUID)
You'll see something like this:

Notice the Body size section, it should be the same size as the BIOS region (for Intel, open the BIOS dump with UEFITool), or the dumped BIOS from the chip (for AMD)
Right click on the second GUID (pictured above for reference) -> Extract body, you'll have your BIOS region* (Intel), or the full BIOS ready to flash (AMD), DMI can be added to it later
* On Intel platforms, use UEFITool 0.28 to replace BIOS region on the BIOS dump from flash chip, regular procedure for cleaning ME region applies (if needed)

Yes done now, I compare the start and the end and of these files that I am extracting from Lenovo .FD file and the dumps from the laptop and they are so identical, I just need to insert DMI infos to the 16MB file and try burning the file to the chip afterwards


thanks

[SMDFlea]

enter 800000 as the length, not the end offset.

Thanks so much wizard. Seems I am so near in my making my first BIOS extracted from a hidden Lenovo .EXE.
From the screenshot uploaded on Imgur seems everything is OK?





So when I create these 2 new files then I need to also take the DMI infos from the DUMP of my laptop and write only to the 16MB file at addresses:
DMI 42000 - 43FFF
and write that file to the chip?

do I need to make any modification to the 8MB BIOS or write it as such Virgin as extracted from Lenovo .FD file, or it can be bypassed fully and not written at all?

Thanks once again

Maybe the packer of my BIOS for Lenovo V15 G3 IAP is different (not TDK) because when I unpacked it I am just getting .FD file which is 24 MB in size. After unpacking .FD file further with CLI extractor I got a bunch of files and folders like:
0 Descriptor region,
1 Padding,
2 Boot partition ,
3 Data partition,
4 Boot partition and inside those folders there are a plenty of small body.bin files. So I am not getting only one .BIN file which should be 16MB in size to further flash it via RT809, all those files and folders properties are less than 10 MB

It isn`t a phoenix TDK bios, it`s Insyde. Search for the word BIOSIMG in the FD file, the line just below that is the start offset at 1E6BB0.

Hi guys, will anyone be able to check this file to see if I did it correctly.....also can anyone guide me on how to disable the on-board RAM via the bios for Lenovo 15ADA05 laptop

Yes it`s ok you did a good job. Try the patcher to disable ram, don`t know if it will work on this model or not - https://www.badcaps.net/forum/troubl...20#post3232220

This is so helpful my friend. SMDFlea Hi buddy! Thank u so much. I finally lined up my 4 laptop bios for modding. May you guide me to a Lenovo BIOS Editor for Phoenix BIOS? I'm looking to flashing CH341A modded bios with enhanced parameters like igpu clock to 1Ghz from 760Mhz & UMA frame buffer & temperature limits & fan speed control & cTDP adjustment among others.
May you advise, please?
Thanks

Hello,
I have a Lenovo V14-ADA 82C6
S/N: PF278NFW
I tried to extract and edit the bios from the Lenovo update file by using your tutorial. I think it is not a Lenovo Phoenix TDK Bios. I attached the original/downloaded from lenovo bios.cap file and the extracted and edited bios.cap file. If someone could take a look and tell me if did it rigth. Thank you.

Re: How to extract and edit a Lenovo Phoenix TDK Bios

great thread, I followed the procedure to extract the bios but ended with a file 8193bytes, and I understand its supposed to be 8192, where did I mess? tried it twice, will cut one byte from the top, then one from the bottom, and check. just asking this as a curiosity. thank you. sorry to resuscitate this one, not trying to necropost, just thinking other people might have the same issue in 2023, thanks. (Lenovo B80 40 LA2092P Rev 3.0)

yes... the extracted bios is longer... use the HxD program (which is free) and cut it to the correct size (cut the header)... keep reading.. you also have pictures .. SMDFlea explained very well.

Followed your instructions and saved Lenovo Ryzen 5 laptop from bad BIOS!
Thank you!

Re: How to extract and edit a Lenovo Phoenix TDK Bios

The update also has an EC update, offsets 800000 - 81FFFF (length 20000). To copy your DMI,the serial number etc,open the bios with UEFITool and copy/replace the first padding area, or use a hex editor using offsets 180048 - 183FFF

.

Hi again, there is something that I don't understand about the EC Update. In the offsets 180048 - 183FFF are saved the DMI, serial number, etc. This offsets are from the backup BIOS? Then I have to replace them in the EC Update that I extract from the Update, and then the EC in the new BIOS, right?

Now, how I identify the EC offsets in the new BIOS?

[ranixon]

Re: How to extract and edit a Lenovo Phoenix TDK Bios

Scroll down until you find the first big chunk of hex,its starting at 1D0000 .The end off-set of your 8MB backup is 7FFFFF ,select 1D0000 and 7FFFFF off-sets in the update,copy and save into a new file.It isn`t a full bios image,only a bios region.

Thank you for your answer. I selected the regions, but both sizes are different. 6815744 for the backup, and 6488064 for the region. Should I replace only a part of it or I selected more than I should

Copied section


Backup

You can copy that over your old bios with a hex editor or use UEFITool 0.25 to replace it.The update also has an EC update, offsets 800000 - 81FFFF (length 20000). To copy your DMI,the serial number etc,open the bios with UEFITool and copy/replace the first padding area, or use a hex editor using offsets 180048 - 183FFF

The padding area in the BIOS that I copied?
