    Dell Vostro 3750 Bios Dump needed

    Hi guys,

    I've a Dell Vostro 3750 laptop(da0r03mb6e1 rev:e) with bad bios.
    I downloaded the bios from the dell website after I extracted the exe file I got so many files but neither one matches with the chip size. I don't have any idea how to get the right file out of the exe.

    Anyone has dump files for this laptop?

    I would really appreciate any help.

        Hello,

        First of all I'd like to thank you.
        I tried this method on my computer Win 7 64bit and whenever tried it my OS locked up. I tried it on my other computer and the same thing happened.
        Now I tried it on an 32bit OS and it worked.

        I still have a question.
        I was able to read and save the bios from the bios chip and the size of the file was 4MB this is 5MB. So this one is larger than the chip size. Could this be a problem?

        The other thing is I still don't know how I can get the dumb file for the EC chip?

        Thank you again!
