Firmware archive of 1.93 MB titled 24_Combined_ME++ with an 8 MB marker, meaning the enclosed image is likely sized for a 64 Mbit SPI chip. The name points to a combined BIOS plus Intel Management Engine image, but no device or board number is given. Treat it as unverified until its source is confirmed against the board. Before writing it with a programmer, dump and save the existing chip, confirm the flash part is 8 MB, and check that the descriptor and platform suit the hardware.
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 @skclappybios. Enginerys does not host this file.
