Original SPI dump from a Lenovo ThinkPad T14 Gen 3 mainboard, LCFC NM-E441 rev 1.0, tagged with the serial-style identifier PF44FF8X and marked OG for an original read. The raw BIN is 32 MB, matching a 256 Mbit flash. Because it was read from a specific unit, it may carry machine serial and board data, so a technician may need to adjust identity information for a different board. Back up the current chip with a programmer before writing, and ensure the board number and revision on the PCB match.
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 @sboisworld. Enginerys does not host this file.
