BIOS image for the MT50IN1 board, version V.02, labelled for both DNS and Casper CKY laptops, delivered as a ZIP of about 2.9 MB. The shared board number shows the same platform is sold under these brands. Typical use is reprogramming the SPI flash with an external programmer after a corrupted update or a no-boot fault. Make sure the PCB carries the MT50IN1 marking, keep a backup of the existing chip dump, and verify the file size equals the flash capacity before writing.
