BIOS image for the Acer Aspire 5253 laptop, stored as a 2.00 MB .fd file. The name states no motherboard number or revision, so compare the board label before trusting it. A 2 MB image corresponds to a 16 Mbit SPI flash chip, and the .fd extension is common for Acer/Insyde firmware files.

Always dump and keep the original chip contents before erasing and programming.
