How to update Dell R320 BIOS and iDRAC

This Dell R320 was previously a domain controller at a small branch office. When that office closed, we decided to repurpose it as an Ubuntu server to run tape backups. When I get a piece of hardware like this the first thing I do is wipe the settings clean and do administrative updates. Here are the steps I followed:

2. Find the .efi style of firmware and download it
