BIOS for the Gigabyte GA-N3050M-D3P desktop motherboard, revision 1.0, packed in a RAR archive. A dump like this is used when the board fails to POST after a bad update or the flash contents are corrupted, and is written directly to the SPI chip with a programmer. Gigabyte boards often carry DualBIOS chips, so check whether yours has one or two. Read and save the existing contents first, confirm the PCB revision label, and make sure the image size matches the flash chip before writing.
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 →
