Firmware dump labelled DT-350, packed in a RAR archive of roughly 38.6 MB; the name gives no brand, board revision or flash chip type, so the exact device must be confirmed before use. A dump of this size likely covers a larger NAND or eMMC style memory rather than a small SPI BIOS. Technicians use such images to restore a device whose firmware is corrupted, programming the memory directly. Open the archive, compare file sizes with the chip on the board, and back up the existing contents before writing anything.
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 →
