BIOS dump for the Casper CKY laptop on board MT50IN1, version V.02, compressed into a 2.9 MB RAR. The MT50IN1 platform is shared by several brands that rebadge the same design. A dump like this is written to the SPI flash chip with a programmer such as a CH341A to revive a board that does not start or shows a black screen. Read and save the original chip contents first, check the board marking matches MT50IN1, and confirm the image size fits the flash chip.
