Original BIOS dump for a Toshiba Satellite C840 with part code PSC6EL, the name suggesting an untouched read from the chip. The binary measures 4.00 MB, the size of a 32 Mbit SPI flash. An original read is useful as a clean reference or for restoring a board after a corrupted update, written with a programmer such as a CH341A or RT809. Before flashing, read and save the current chip contents, confirm the flash capacity, and check the motherboard number on your PCB against the donor unit.
