BIOS firmware for the Samsung 300E5K laptop on the BA41-02501A mainboard, with project code K2-15BDW at revision 1.0. The name hints at a Broadwell platform, though that is not stated outright. Samsung marks its own boards with the BA41 prefix, so match that code and the revision on the PCB before flashing. The RAR contains a dump for writing to the SPI chip with a programmer, and reading the original chip first gives you a backup to restore if anything goes wrong.
The button opens the matching file on RM Schematics, or a source page if it is not catalogued there yet. The original attachment is from @biosarchive. Enginerys does not host this file.
