BIOS image labelled PREMIUM 12800 PLUS, carrying version string V(23307) and a build date of 16 November 2021, supplied as a raw .bin of about 7.86 MB. The name gives no laptop brand or board number, so the target hardware has to be confirmed from the sticker or the existing chip contents before use. Raw images like this are written to the SPI flash with a programmer such as a CH341A. Read and save the original chip first, and compare the file size with the chip capacity, since an image that does not match will not fit.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @tvsoftwareworld. Enginerys does not host this file.
