Edited EFI dump for a MacBook Air A1465 taken from an MX25L6405 chip in SOIC-16 package, provided as a 3.94 MB 7z archive. No logic board number is given, so confirm compatibility from the 820- number on your PCB before use. The EDIT tag suggests the image was modified, likely to clean or reset parts of it, though the name does not say how. The Macronix MX25L6405 holds 8 MB, so the image size should match. Back up the original chip before writing with a programmer.
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 @biosfiles. Enginerys does not host this file.
