Firmware set for board BM5166 version 1.3, an 8.30 MB RAR that according to the name contains a 32 MB image, a 2 MB image and a Type-C related file, probably for the USB-C or PD controller. Each file belongs to a different chip, so identify every flash chip and its capacity before programming. The name does not say the laptop brand. Check that the board marking reads BM5166 version 1.3, and read and save all original chips with a programmer before writing replacements.
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 @biosarchive. Enginerys does not host this file.
