BIOS dump for the ASUS D300TA, stated in the name to be for a 16 MB flash chip and supplied as a RAR archive. A 16 MB image matches a 128 Mbit SPI flash. Technicians use such a dump to recover a corrupted BIOS by writing it with a programmer such as a CH341A or RT809. Read and save the original chip contents first, so serial numbers and board-specific data can be restored. Make sure the extracted image size matches the chip capacity, otherwise it 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 @biosarchive. Enginerys does not host this file.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
