Original BIOS read from an ASUS X550CC, labelled as working and original, saved as an 8 MB .bin file. The size matches a 64 Mbit SPI flash chip. A known-good original dump is useful for restoring a board whose firmware is corrupted, or for comparing against a suspect chip. X550 boards came in several revisions, so match the board revision on the PCB before writing. Always back up the current contents first, and expect serial and system data to be those of the donor unit.
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 →
