Firmware dump for a Lenovo laptop on Compal board LA-J701P, with project code FLMAO and a date of 10 June 2020, marked as working. The 8.80 MB RAR holds the image intended for the board BIOS flash. Compal uses the LA-xxxxP pattern for its motherboard numbers, and the code before it identifies the project. Technicians write such dumps with an SPI programmer to recover dead or boot-looping boards. Compare the number on the PCB, read and back up the original chip first, and check that the image size matches the flash.
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 @bios_main_ec_kbc. Enginerys does not host this file.
