BIOS dump for an HP X360 convertible built on board 14257-2, a number that follows the Wistron pattern used by the ODM that designed the mainboard for HP. The name indicates an 8MB image, so it is meant for an 8MB SPI flash chip, packed in a RAR archive of about 4.3 MB. Technicians use such a dump to recover a bricked board by writing the chip with a programmer such as a CH341A. Confirm the 14257-2 marking on the PCB, read and save the original chip first, and verify the extracted image is exactly 8MB 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.
How to open a .rar 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 →
