Main BIOS image for a Casper laptop whose name mentions only CHD and an NVIDIA GPU, which points to a discrete graphics build. It comes as a 2.84 MB RAR archive, with no board number, revision or flash chip given. Because of that, compare the PCB markings and the chip on your board before trusting the image. Technicians flash dumps like this with an SPI programmer to revive boards that power on without display. Always read and archive the original contents first, and confirm the image size fits the chip.

Compressed archive — the usual wrapper for a schematic + boardview pair or a BIOS + EC set.
Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
