BIOS dump for the Toshiba Satellite C850 built on mainboard 6050A2540701, revision MB-A02, marked as tested. It comes compressed in a rar archive of about 3 MB. The 6050A board number follows the Inventec pattern, so the PCB was made by Inventec for Toshiba. Typical use is reprogramming the SPI flash chip with a hardware programmer when the laptop shows no display or is stuck in a boot loop. Read and save the original chip contents first, and confirm that the image size matches the flash capacity before writing.
