Microserver N54L/N40L Custom Bios Update (Jan 2014)


You do not need to do this you don't want to. There is a risk that you will brick your microserver. Do so at your own risk.

The main reason I see for updating is to enable hot swappable drives (which means you can plug in drives while the server is on)

What You Need:

USB drive that will be formated (it will lose all its data)



No point re-inventing the wheel, there is a good guide for this here. Skip to the "Step-By-Step Guide – Critical Path Check List" section, but instead of using the files they link to, use the ones above to get the latest BIOS.

When you have succesfully installed the BIOS, restart the microserver and press F10 to enter the BIOS. Follow the steps on the previous link labeled: "Modifying the BIOS"

And that should be it fully installed and ready to go!


  1. Custom software development specialists explore exactly what it is a company does - what the necessities of the company are on a day to day basis and what they need from their IT system in order to operate to their optimum. In order to perform efficient functionality, a company would ideally need its software to do exactly what they want it to.

  2. Any chance of newer 2015 files / modded bios for the N54L ?

    Thank you

    1. Hi,
      That would be great if new features have been added to the original one.
      Thanks in advance for your answer.
