Samsung SA300 LED monitor firmware for model S20A300B, supplied as a 512 KB raw binary sized for a 4 Mbit SPI flash chip. It is a second copy under the same name as another dump, so compare checksums to see whether the two differ, as they may come from different panel or board versions. Technicians program it into the main board flash to fix boot loops, no picture or a dead standby LED. Back up the existing chip contents first and check the board markings before writing.
