A 32 MB BIOS image for the ASUS X1404ZA on mainboard revision 2.0, stored as a raw .bin file and noted as OK. A 32 MB image is meant for a 256 Mbit SPI flash chip; it will not fit a smaller part, so verify the chip marking first. Write it with a hardware programmer such as a CH341A or similar using a clip or after desoldering the chip. Revision 2.0 boards may differ from later revisions of the same model, so match the PCB label and keep a backup of the factory dump.
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 →
