Dump saved by programmer software from a Macronix MX25L3205 chip, timestamped November 2016, with a size of 4 MB that matches the 32 Mbit capacity of that flash. The name contains no laptop model or board number, so the source platform is unknown. Technicians keep such reads as backups or donor images for SPI reflashing. Search the image for vendor and model text before use, confirm the chip type on your board, and always back up the existing chip before programming anything over it.
