Firmware dump labelled for a Toshiba Satellite C850 type board, carrying the number 10028 and noted as an Intel Core i7 configuration with an ok status mark. 10028 most likely refers to the board revision code, though the name does not state it explicitly. The 4.00 MB binary suits a 32 Mbit SPI chip and is meant for programmer flashing after a failed update or corruption. Back up the original chip, compare the board marking with the number in the name, and confirm the image size matches the chip.
