Firmware dump for the Samsung NP300E4X notebook series, marked in its name as fully working, in a 2.47 MB RAR archive. The image is meant for the SPI BIOS chip and is typically written with a CH341A or similar programmer when a laptop shows no display, loops on power or fails after a bad update. Several board versions were used across the NP300E4X range, so compare the board number on the PCB with whatever notes come in the archive. Read and save the original chip first, and check the image size matches the flash.
