BIOS dump for an S300CA mainboard, delivered as an 8 MB .bin file with no revision or version noted. S300CA matches an ASUS VivoBook model code, though the name does not state the brand. The size matches a 64 Mbit SPI flash chip, and the file is intended for direct programming with an external programmer to recover a board with corrupted firmware. Check the board revision printed on the PCB, since images can differ between revisions, and read and save the existing chip first.
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 @bios_laptop. 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 →
