OK here it is. I want to learn to extract main and EC bios for this notebook because it is very specific, the exe file can't be extracted with UniExtractor, instead I used PE Explorer method from this link: http://www.vlab.su/viewtopic.php?p=33735#p33735

The notebook is:
Lenovo B50-30 Model: 20382
ZIWB0/B1/E0 LA-B101P Rev.1A
2014-06-12

Intel® Pentium Processor N3540 (SR1YW)
nVidia N15V-GM-S-A2
Multi: Nuvoton NPCE288NA0DX

First I go to Lenovo support and enter machine make and model and I got bios file for download: 9ccn35ww.exe



When I try to extract with UniExtractor I receive the following message:




Than I use PE Explorer and get this:



After that I open the exe file with WinHex and mark the beginning 1D200



And the end: 1D200 + 4F998 -1 = 43CB97 (it is the end of file anyways)



And make a new file from this data: download

New file is 4.12MB but original bios is 8MB. What to do next with this? I am stuck here.

My uploaded bios file is here and it is 8MB.

What next? Thank you!

Thanks to Фрекауцан Михаил (дядьмиша), I now know how to extract bios from this file. If someone is interested, here it is how to do it:

Download: Universal Extractor 1.6.1.1020 от korosya, if this link is not working, try the website

Than unpack it to a folder of your choice and use it on a file you need to be unpacked. After fist unpacking you will get this:



After that, use Uniextract once again on the first file 9CCN35WW,1.EXE and you will get this:



The file Merge.bin is our needed file with bios images. Inside there are couple of images. Use your favorite hex editor and search for string: _BIOSIMG. From the row below starts your main bios image.



Than look for _EC_IMG and from the row below it, start your EC bios.



Copy the required lenght into new file and save both bioses.

Thats all.

Большое спасибо Фрекауцан Михаил (дядьмиша).

The Bios of Lenovo is packed "Inno Setup Packer".
Оnce one method how to make unpacking bios of Lenovo:
1. download The Inno Setup Unpacker from http://innounp.sourceforge.net.
2. make in shell: innounp BiosOfLenovo.exe
3. you get directory named "app" where located "clean" files which you can unpack using 7zip-like unpackers.
4. Take file Merge.bin and cut it...
