Firmware for the I-45C motherboard, a 392 KB ZIP containing the BIOS image. The file name lists no version or revision, so identify the image once extracted. A sibling package exists for the I-45CV, so verify which variant is on the bench before flashing. Technicians use such dumps to repair no-POST faults caused by BIOS corruption, writing them with a CH341A-type or similar programmer and verifying afterwards. Dump the original chip first and confirm the image is exactly the size of the flash chip installed.
