Samsung NP-R525 laptop BIOS in the JT06RU configuration, stored as an 899 KB RAR archive. No board number or chip type is given. Such a dump helps restore a machine that will not start after a corrupted flash, by writing the image to the SPI chip with an external programmer. A second R525 dump with another suffix exists, so compare the BA41 code on your PCB with the donor before choosing one. Save the existing chip and confirm the extracted image matches the chip capacity.
