BIOS image for a Toshiba Satellite C855D-169 with model code PSCC2E, a UMA version meaning integrated graphics without a discrete GPU. The binary is 4.00 MB, matching a 32 Mbit SPI flash chip. Technicians write such dumps with an external programmer to revive a board with corrupted firmware or a failed update. Make sure the graphics configuration matches, since UMA and discrete-GPU boards need different images, back up the original chip first, and compare the motherboard number on the PCB.
