Second 4 MB copy, marked (2), of the 4530S firmware dump, stored as a raw binary. The name carries only the model code, with no board number, BIOS revision or ME note. Two separate reads are useful for checking each other, because files that differ may point to a faulty read. The image fits a 32 Mbit SPI chip and is written with a programmer such as a CH341A or RT809. Back up the existing chip before writing, and confirm that the board matches the model this file came from.
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 @biosfilebins. 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 →
