Firmware dump attributed to an Acer Aspire, given without a file extension and weighing exactly 2.00 MB, which corresponds to a 16 Mbit SPI flash. The name carries the strings 57385338 and ms2264, the second of which may be an internal board or model code. Neither is decoded here, so verify the model sticker and board markings yourself. Use a hex editor to confirm the content is a real BIOS image rather than an empty read. Then flash it with a programmer, keeping a backup of the original chip.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @ComputerBIOSBinFile. Enginerys does not host this file.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
