BIOS dump archive tied to Compal board LA-5123P, with NB255 also mentioned in the name, likely a Toshiba NB255 netbook model reference. The RAR is small at 562 KB, which suggests a compact flash image, possibly with EC data inside. Compal uses the LA-xxxxP numbering across many brands, so match the number on the PCB exactly before use. Read and back up the existing SPI chip with a programmer first, and confirm the extracted 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 →
