Second copy of a 16 MB BIOS dump for board 15341-1, a Wistron-style motherboard number, with the extra tag 91n85 in the name. The size fits a 128 Mbit SPI chip, the kind found on many Wistron-built laptop boards. It can be compared byte for byte with the other copy to spot read errors before programming. Check the board number and revision printed on the PCB, back up the original chip contents, and verify after writing with your programmer software to confirm a clean flash.
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 @biosfilebins. Enginerys does not host this file.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
