BIOS archive for the Sony VAIO SVF15N26CXB, RAR format, about 3.8 MB compressed. No board revision, version or status is given in the name. Technicians extract such packages to obtain a flash image that is then written to the SPI BIOS chip with a hardware programmer to fix a laptop with corrupted firmware. Inspect the extracted file, compare its size with the chip capacity, and back up the existing chip before writing. Also confirm that the motherboard matches the SVF15N model in question.
