Firmware package for an HP notebook with the TPN-C105 regulatory model, built on the Compal LA-8551P mainboard, containing BIOS and EC images in a 3.72 MB rar archive. TPN codes are HP regulatory identifiers printed on the bottom label, while LA-xxxxP is the Compal design number on the board. Useful for reflashing a bricked BIOS or a misbehaving embedded controller with an SPI programmer. Keep a backup of the original dump, since serial and product data may be stored there, and verify the image size matches the chip.
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.
