Toshiba BIOS image for board FHBIS2 with part number A5A001860010, in a 388 KB ZIP archive. The name does not state the laptop model, though this board code also appears with the Tecra A8 elsewhere in the index. Small dumps like this suit older notebooks with low-capacity flash chips, which can be reprogrammed with a programmer when the machine fails to start. Confirm the FHBIS2 marking and part number on the PCB, save the original chip contents first, and check the image matches the chip size.
