The is a specialized, compact motherboard frequently utilized in HP Slimline and Compaq desktop PCs. These systems are often branded with custom HP names (such as "Nutmeg-P" or "Nutmeg").
: These official installers may not contain a raw .bin suitable for direct SPI flashing without manual extraction using tools like UEFITool or 7-Zip . Technical Identification
If you can share board you have (e.g., model number, chipset, CPU support), I can help you find official resources, datasheets, or community notes – without touching the binary itself.
: Plug the programmer into a working computer and open flashing software like NeoProgrammer or AsProgrammer.
If flashing via software or DOS, use an Uninterruptible Power Supply (UPS) to guard against sudden power cuts.
Transfer the nutmegminiitx_rev10.bin file and your flashing utility (e.g., flashrom.exe or the vendor-specific tool) to the root directory of the USB.
Format a USB flash drive to FAT32 using Rufus and make it bootable (FreeDOS).
sudo flashrom -p ch341a_spi
Always dump the current (even if corrupted) BIOS content before overwriting it.
HP provides the for Nutmeg motherboards (SSID 2B28) as SoftPaq SP75164.
Compare the output to the hash provided by the source. If no hash is available, open the file in a hex editor (like HxD). The first 64 bytes should look like structured code (jump vectors), not all FF or 00 .
Do not use a 4 MB or 2 MB BIN file on the Rev 10. The board expects a specific memory map; incorrect sizing will brick the CMOS sector.
