BIOS dump for the Acer Aspire 4741 on the Wistron JE40-CP motherboard, number 09920-2, in a 1.71 MB RAR. The five-digit number with a dash suffix is Wistron's board numbering, where the suffix marks the PCB revision. JE40-CP is the platform designation shared by several Acer and Gateway models. Technicians use the file to reflash the SPI chip with a programmer to repair a board that will not start. Match the revision, back up the existing chip, and confirm the image size.
