Firmware archive labelled for the Microsoft Surface Book 2, carrying the board reference M1023323-006. The name describes the contents as an outimage of 16 MB, a full flash readout, and marks it as checked OK. Such a dump is used to recover a board that will not boot or post after SPI corruption by writing it straight to the flash chip with a hardware programmer. Back up the existing chip contents first. Make sure the board reference matches and that the chip capacity is 16 MB, since a mismatched size will not fit.
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.
