Standard retail motherboards get regular updates directly from a manufacturer’s website. OEM boards like the H110D4-M1 are different:
If you are reading this, you likely own a Pegatron H110D4M1 motherboard. You probably salvaged it from an Acer, Asus, or HP prebuilt (like the Acer Aspire TC series).

In Linux environments, you may also need to prepare the repacked BIOS by extracting it properly—for example, using commands like tar -xvjf bios_package.tar.bz2 to unpack the firmware file. : Format a USB flash drive as FAT32
