BIOS and EC firmware for an all-in-one PC built on Compal board LA-C671P with project code AIA30, archived in a 3.90 MB RAR file. The name gives no brand, version or flash chip details. LA-prefixed numbers follow Compal's board numbering, used across many OEM systems. Technicians use such files to reprogram the SPI BIOS chip and the embedded controller firmware when a unit is dead or stuck after a failed update. Verify the board number on the PCB, back up the original chips, and check that each image size matches its target flash.
