Firmware pack for a laptop board with Compal number LA-J081P, described as a working BIOS that solves a TPM alert at boot. No brand or model is stated in the name, though LA-xxxxP is Compal's ODM board numbering, used for several laptop makers. Contents are likely the SPI BIOS image and possibly EC firmware for reflashing with a programmer. Dump and keep the original chip contents before writing, verify the board number on the PCB, and ensure the image size matches the flash chip.
