BIOS dump for a board with Wistron code 15080-1, project name HAMAR, also tagged with part number 384-05A06-011, in a 4.12 MB RAR. No laptop brand is stated. Wistron identifies projects by code names and five-digit board numbers with a revision suffix like this, so check the PCB label matches. Before writing with an SPI programmer, back up the original chip contents and confirm the image size matches the flash capacity, since an oversized or undersized file will not program correctly.
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.
