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

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?...

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

Got the DMI infos as you propose on other thread with Hxd from my DUMP backup attached here in the thread, and Paste Wrote with HxD at the exact addresses (DMI 42000 - 43FFF) on the 16MB file that you shared, and wrote the full file with RT809 but again the same the laptop doesn't power ON

My laptop infos are :
Serial PF4A83NG
Model Name V15 G3 IAP
MTM: 82TT00A5RM
MO: PF9XB3512123...

As I wrote this 16MB file and it did not work, now I notice that there is a fresh new BIOS uploaded on Lenovo site, but I am unable to extract both the firmwares.bin from that file using this tutorial here:

Can you help us out or tell how to do extraction of this new file here at this link?

Which one of the chips is EC if you can tell me, because the 2 chips that are near one another are one Main chip 16MB in size and the other one is 8MB which I don't believe is the EC chip as EC chip has 256 KB in size when dumped?

Best regards...

Wrote the first file 16MB in size after I made a backup first which is also 16MB in size, and now it behaves a little differently, but still no power ON laptop. I read also the second chip near it which is 8MB in size and uploaded here if you can help me, thanks so much

P.S. I didn't wrote the second file that you have here which is 256 KB in size as my second BIOS chip is 8MB in size after reading backup..,,...
