First of all, i have searched everywhere for the schematics which will match the components on the motherboard. Unfortunately, none are found that will match many components on the motherboard. So after a while after so many tries, I finally found the original and mainly working Bios for clevo w25cev or 6 71 w25w0 d03a laptop motherboard which I am very happy to share with you. All files are attached below.
Thank you.
