Re: how to extract exe file

Try with Universal extractor

Re: how to extract exe file

it depends of format of exe file or compression implemented
(sometimes file have overlay, sometimes compressed exe in resources, etc...)

this is inno scripted setup module which has specific compression

you can use this tool to unpack

http://sourceforge.net/projects/innounp/files/

anyways here is upacked files

but bios extracted is uefi capsule file, not plain bin or rom so it cannot be flashed bu itself it need more work

good luck

Use the latest version of innoextract .

https://constexpr.org/innoextract/fi....8-windows.zip

Usage

To extract a setup file to the current directory run:

innoextract <file>

The extracted files will go into the app folder. Delete that app folder before you use innoextract again with another bios.

Re: how to extract lenovo bios exe file

After using innoextract you will get an exe file in the "app" folder. This can be expanded with 7zip. Within the resulting files is one .ROM that contains the binary. Just edit it with an hexdecimal editor and remove the header and the final part.
Also open with the editor the original dump file to recognize the header (usually 5A A5 F0) and look for it inside the .rom. The bios image starts one line before this header, and ends 8MB after (or 16, depending on sizeof the bios). You can select the entire image (80000(H)), cut it , and paste on a new file. Save this as Biosxxxx.bin and That's all!
Sorry my bad english, and thank you Google translator!

Sorry. The size for 8MB bios is 800000(h).

Re: how to extract lenovo bios exe file

Hey guys.
Could anyone please help me extract the bin file from this bios, for Lenovo V110-15IAP ?
I tried using innoextract , but I got got a .cap file and a .bin file, but the bin file is too small I think, the .cap file on the other hand seems to be around the proper size, 9MB or so.
The problem is that if I try to use the .cap file with CH341A it gives an error "file length beyond range will be ignored". I even tried converting the .cap file to .bin, but it gives the same error.

Re: how to extract lenovo bios exe file

The cap file is what you need to make your bios , as ala borbe say ( post 3) : but bios extracted is uefi capsule file, not plain bin or rom so it cannot be flashed bu itself it need more work.

so you need a HxD and your old dump to create your bios , maybe this tutorial help you :https://www.youtube.com/watch?v=7qESTVi_DVg&t=150s.

Re: how to extract lenovo bios exe file

You need to use a hex editor to make the bios the correct size.The smaller file is an EC update,ignore that.
The 1MCN54WW.cap CAP header length is 318 ,select block 0-317 delete it.Then select block 0-7FFFFF ,(or length 800000) ,copy it into a new file and save it.Find your old DMI info in your old bios backup,if you have one, and copy it to the new bios.If you do have a bios backup post it in a new thread if you get stuck.
EDIT: Watch the youtube vid posted by @lapfix or follow the second half of this guide - https://www.badcaps.net/forum/showthread.php?t=80861

Thanks man, I'll try and see if I can manage editing it using that tutorial.

Thanks for the help. I'll try doing that.
I will post the backup file tomorrow in this thread.
