Update HP Proliant Microserver BIOS without Windows

I wanted to update my MicroServer Gen8 bios to the latest version but the download site on HPE only showed .EXE files. Since I’m only running Linux on my machines it was not possible to execute that file.

You can however update the BIOS via ILO (Integrated Lights Out) if you extract the BIOS file from the executable.

First download the .EXE from the HPE site: https://support.hpe.com/hpsc/swd/public/detail?swItemId=MTX_e9bfdf20809a426cb16ef9cd81

(Currently the latest version is SP99427.exe. If you want to be sure you’re using the latest BIOS then click the tab “Revision History” to see if there are newer BIOS files available)

Extract the contents of the executable. Have a look at the directory structure below and extract the file marked "CPQJ06xx.xxx"(where “x” might change depending on versions)

Then log in to ILO and navigate to the page “Firmware” via the Menu Option “Administrator”

At the bottom of the page select “Browse” to select the CPQJ06 file and then click Upload.

Let the upload complete and reboot your Microserver. When you start the microserver it displays the BIOS version and date in the first line.

You can also see the version in the ILO overview page.
