Apple A2338 MacBook Pro dump for logic board 820-02020-A, taken from chip UF260 and archived as a 252 KB RAR. The A2338 belongs to the Apple silicon generation, where this location holds a small serial flash rather than a classic EFI BIOS chip. Apple marks boards with 820-xxxxx numbers and a revision letter. Use the file only after backing up the original chip, verifying the designator and board number match, and confirming your programmer supports the exact flash part fitted.
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 @biosarchive. Enginerys does not host this file.
