Raw BIOS image covering the ASUS E502S and E402SA notebooks on mainboard revision 2.1, supplied as an uncompressed 8.00 MB .bin file. An 8 MB size corresponds to a 64 Mbit SPI flash, so the target chip should match that capacity. Technicians typically write such a dump with an external programmer when a unit shows no display or fails to boot after a bad update. Check the revision printed on the PCB matches 2.1 and read out the existing chip before erasing it, so the original serial and settings are preserved.
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 @schematiclaptopramkushwaha. Enginerys does not host this file.
How to open a .bin 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 →
