Firmware image for a Casper laptop using the MB40IA1 mainboard, revision 01, archived as a 1.50 MB 7z file. The name mentions no GPU, chipset or flash chip details. Dumps of this sort are used to recover a board with corrupted BIOS by writing the SPI chip directly with a programmer clip or after desoldering. Check that the PCB silkscreen shows MB40IA1 rev 01, read and store the original chip first, and confirm the extracted image is the same size as the flash device.
