Raw BIOS dump labelled only 4620 and acer, most likely for an Acer model with the 4620 number, though the name gives no board number or revision. The file is a 1.00 MB .bin, matching an 8 Mbit SPI flash chip. Images like this are written to the BIOS chip with an external programmer to repair corrupted firmware. Because the name is so brief, confirm the motherboard number on the PCB against a known source and save the existing chip contents before overwriting anything.
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.

A raw, byte-for-byte image of a flash chip: the main BIOS / UEFI, the embedded-controller (EC) firmware, or both.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
