BIOS dump for the HP 15-U483CL laptop, board DAY62PMB8E0, marked in the name as working. The DA prefix with an MB designation follows Quanta's board numbering, and the 5.10 MB RAR archive holds the image. A dump like this is written to the SPI flash chip with a hardware programmer such as a CH341A to recover a corrupted BIOS or a no-boot board. Read and back up the original chip first, and check that the image size equals the flash chip capacity.

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 →
