Hi all, I do apologize for this seemingly simple question. After a week of googling and reading many posting, I am still having problem to extract the BIOS of BIOS update from Lenovo. It becomes in an exe and iso form. I have tried the posting here suggesting to use WINRAR/7z, universal extractor, or even manual going to the temp directory when executing the update to see the file generated there. Or reading iso file. None of them have resulted to a success in extracting the BIOS. I even used InnoInstaller unpacking on it none have resulted in anything. I am sure there must be an easy way of doing that as I see many people are editing their BIOS. So please help me to with specifics (step by step) of how I should get there. believe me I have tried all I could put my hands on, none have worked. here is a link for what I need to unpack and extract the rom from. And many thanks again. support.lenovo.com/fr/en/products/laptops-and-netbooks/thinkpad-x-series-laptops/thinkpad-x230/downloads/DS029187 Artimes PS:The forum does not let me put a link because I have not posted enough. Basically it is update version 2.66 for x230.
