Raw 4 MB binary firmware image named Ph61tz, most likely a desktop motherboard BIOS dump judging by the name, though the file itself does not state the brand or board revision. A 4 MB size corresponds to a 32 Mbit SPI flash chip, so confirm the capacity of the chip on your board before programming. Read and save the original contents with a programmer such as a CH341A first, then compare the dump against it. Verify the chip ID and the board model on the PCB, because a mismatched image can leave the system without video or POST.

Back up your own chip before writing any dump, and match the full board number and revision. Flashing guide →
