BIOS image for the Dell Inspiron 15 7577, with CKA50 and CKF50 noted alongside Compal board LA-E992P, in a 6.03 MB RAR. CKA50 and CKF50 look like Dell board-level codes for this platform, while LA-E992P is Compal's own number printed on the PCB. Write the dump with an SPI programmer to recover from a failed flash or a corrupted region. First back up the original chip, which stores the service tag and other system data, and make sure the image size equals the 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 →
