Firmware archive for the Samsung NP300E5X laptop line, delivered as a 2.46 MB RAR. No board number, revision or chip size appears in the name, so the contents need to be examined to see which image and variant are included. NP300E5X covers several sub-models, and Samsung boards carry a BA41 code on the PCB that is worth comparing with any notes inside. Dump the original SPI chip with a programmer first, verify it, and confirm the image size matches before writing.

How to open a .rar file
Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
