Firmware set for the Samsung NP270E5K notebook built on main board BA41-02455A, packaged as a RAR of roughly 9.5 MB. According to the name it holds both the main BIOS and the KBC, the keyboard controller or embedded controller firmware that Samsung laptops store separately. BA41 is Samsung's own numbering for main boards, so check the full number and suffix on the PCB sticker. Back up both original chips with an SPI programmer before flashing, and confirm each image matches the size of the chip it is meant for.
