BIOS firmware for the Samsung NP100NZC laptop, motherboard BA41-01970A, with the RISA designation and revision 1.1 given in the name. BA41 is the prefix Samsung uses for its own main-board part numbers. The 1.36 MB zip is meant for restoring a corrupted or blank SPI flash with a programmer when the machine fails to start. Read and save the existing chip before erasing it, and confirm the board revision, since other revisions of the same part number may need a different image.
