BIOS archive for the Lenovo B490, Intel platform, marked wifi, packed as a 3.16 MB rar. The label suggests a version patched to bypass the Wi-Fi card whitelist, which normally blocks unapproved wireless modules, but the name does not confirm it. It is used by flashing the SPI BIOS chip with an external programmer, either to allow aftermarket cards or to repair corrupt firmware. Verify the board matches the Intel B490, keep the original dump, and check the image size against the chip before writing.
