This project will cover the change of IDRAC 7 to a enterprise license.
!!#Warning this is just for personal use and should not be used in a enterprise setting only for homelab and educational purposes as this will change the service tag.#!!
For a Copy of this will be also posted on my github.
This is tested on the 12th generation Poweredge servers, Dell PowerEdge R#20,T#20, for sure works on Dell R420(my current system)

Download "OMSA71-CentOS6-x86_64-LiveDVD.iso". It must be this older version, newer versions replaced a tool we want with a dumbed down version. I have Provided a link to download it but you can also just google for it too as no files larger than 25mb can be uploaded to github.
Using the ISO create a bootable drive and load into the operating system (This is a live ISO so you only need to boot to the live desktop and open the terminal)
Enter these commands:
sudo susmbios-sys-info --service-tag --set=9QYZF42reboot nowWhen the system reboot it may come up with an license error or an upgrading screen but just let the system update and start IDRAC.
Login to IDRAC and it will want you to upload a license
Go ahead and view the License.xml or use the following code and save it to a file.xml and upload it as a license.
