Raw 8MB firmware image for an Apple A1465 machine using logic board 820-00164, stored as an uncompressed BIN file. A1465 is the Apple model number given in the name and 820-00164 is the board identifier printed on the PCB. Such dumps are written to the SPI boot ROM with an external programmer when the firmware is corrupted or locked. Back up the original chip first, since it contains the machine serial and other unique data, and confirm the flash chip is 8MB so the image fits without errors.
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 @CLRINDORE. Enginerys does not host this file.
