Firmware archive for the Samsung NP900X3G ultrabook, tied to the Samsung motherboard number BA41-02334A. Samsung uses the BA41 prefix for its own main board part numbers, so the code printed on the PCB should be compared directly with this one before use. The RAR of roughly 4 MB holds the BIOS image intended for reprogramming the SPI flash with an external programmer when the machine is dead, loops on startup or shows no display after a bad update. Read and back up the existing chip first, since serial and configuration data live there.
