Archive holding both the BIOS and the KBC (keyboard controller, the embedded controller) firmware for a board identified as OSAMU2_BT_HPC MV_MB_V1. Having the EC image alongside the system BIOS matters, because many no-power or charging faults on laptops come from a corrupted EC rather than the main BIOS. Flash each image to its correct chip with an SPI programmer. Verify the board name and version V1 on the PCB, dump the existing chips for backup, and make sure image sizes match the chip capacities.

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 →
