Samsung BIOS dump for the NP305U1A notebook, 2 MB, with a 03PS suffix that is probably part of the model or region code. The image is raw .bin and fits a 16 Mbit SPI flash, so it can be written with an external programmer when the existing firmware is corrupted. Check the exact model sticker and the board before writing. Read and keep the original chip first, because machine-specific data such as serials may only be present in the existing dump.
