BIOS image for an HP 17 notebook identified as 17SBU, Inventec board 6050A2549501-MB-A02 at revision A02, intended for an 8MB flash chip. Inventec numbers its boards with the 6050A prefix, and HP is the brand here. The dump helps when a laptop is dead from a corrupted firmware or after a chip swap. Read the existing SPI chip twice and compare the reads before overwriting, keep that backup safe, and make sure the target chip really holds 8MB so the image fits.
