BIOS image, version 2.14, for the Acer Aspire E1-531 built on the Compal LA-7912P motherboard, packed as a 2.86 MB RAR. The LA prefix marks Compal's numbering, so the board was produced by that ODM for Acer. A technician uses this file to reflash the SPI BIOS chip with a programmer when the machine fails to post after a corrupted update. Compare the board number on the PCB with LA-7912P, back up the existing chip, and make sure the image size matches the chip before writing.
