Where's Original backup bios file ?

Not sure what you are meaning? I have looked at the Rules topic to try and find how to backup my current bios but cannot find a guide.
The file attached on first post is extracted from HP SP151254 file - is this the file you mean?

If you know how to use a programmer you can backup the current bios. Contact Youtube. Take for example a cheap programmer, CH341A.
