RAR archive of 3.55 MB holding BIOS together with EC (embedded controller) firmware for a board identified only as JFCHSPI1. No brand or model appears in the name, so confirm the target by the code on the motherboard or flash chip. Having both images matters on systems where a corrupted EC causes no power, charging faults or fan problems. Flash each image to its own chip with an SPI programmer, after reading and storing the existing contents so the board can be restored if the dump is wrong.

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 →
