The NutmegMiniITX Rev 1.0 is a highly sought-after motherboard among small-form-factor (SFF) enthusiasts, retro-computing hobbyists, and custom embedded-system builders. Known for its compact footprint and efficient architecture, this motherboard serves as the backbone for various custom builds, home servers, and low-power workstations.
You can use the following commands in Windows (Command Prompt) to confirm your model and BIOS revision:
The "Rev 10" denotes the tenth revision of the PCB. This is critical because a BIOS file for Rev 8 or Rev 12 will almost certainly on Rev 10. Motherboard manufacturers often change voltage regulators, clock generators, or memory routing between revisions, necessitating a unique firmware binary.

Open-source utilities like AsProgrammer , NeoProgrammer , or Flashrom are highly recommended over older proprietary software due to better chip identification databases. Step-by-Step Hardware Flashing Guide
The , also known as the Nutmeg-P , is a specialized Mini-ITX motherboard manufactured by Foxconn for HP desktop systems like the HP Slimline 450-a12il . Finding the correct BIOS .bin file is critical for users looking to recover a "bricked" motherboard or perform a manual firmware update using a hardware programmer. Core Motherboard Specifications
If the motherboard cannot boot into a recovery menu, you must use an external hardware programmer to write the .BIN file directly to the chip.
: Attach an SOIC8 test clip to the motherboard’s BIOS chip, ensuring Pin 1 (marked by a small dot on the chip) aligns with Pin 1 on the programmer.
This comprehensive technical guide covers everything you need to know about locating, preparing, and flashing the binary BIOS file for this specific motherboard revision. Understanding the NutmegMiniITX Rev 1.0 BIOS BIN File

The PC turns on for 2–3 seconds, shuts down, and automatically tries to restart indefinitely.
A BIOS .bin file is a binary image of the motherboard's firmware. Unlike standard .exe update files used within Windows, the .bin format is required for:
Before you flash, you must verify that the file is not corrupt. Even one flipped bit can destroy the boot block.
