As per convention for most Linux beginners and intermediates alike, the action of "Librebooting" a personal machine is nothing short of a commonality. Founded by Leah Rowe, the Libreboot project aims to create libre "boot firmware based on coreboot, replacing proprietary BIOS/UEFI firmware" and, through this simple yet imperative step to true privacy, one can achieve true digital freedom.[1] It is centered around the elimination of the threat of the Intel Management Engine (IME/Intel ME), which has been infamously speculated to be a potent spying device.
This article has been peer-reviewed for validity, written based on the dangers of hardware-level spying in using Libreboot as an example.
Specific Device Tips
Dell OptiPlex 9020 SFF - Easier Method

In a talk with Leah Rowe herself, there is little to no need for the popular, yet expensive, Pomona Flash Clip. According to Dell's own user manual for maintenance of the device, there are four pins near the RAM slots that allow for the read-only flag of the BIOS to be removed with one female-to-female jumper wire. Thus, this allows the override of the boot image.
- This may sound simple, but please be careful - the process of doing this is slightly hazardous.
In a traditional process, the firmware blob is split into two portions to be flashed onto the SOIC-8 microprocessors. While this will likely work, the very process of not only doing it right with accounting for which processor is which but also the safety of connecting the flash clip may not be worth the extra hassle. It is especially risky on a device like this to make a mistake.
Steps
As it is the easiest distribution to use, this guide assumes you are using Debian to Libreboot your Dell OptiPlex machine.
- Install flashprog and the lbmk repository - Follow the instructions on the Libreboot wiki to use lbmk and build the image from source. The Dell OptiPlex 9020, after compiling your image should be named "dell9020mt_12mb."
- Flashprog, too, must be made from source - clone this repository and follow these directions.
- Libreboot warns against the usage of flashrom. You may use it, and according to Leah Rowe, it is almost exactly the same - however, flashprog is actively maintained.

(I will soon fill this out properly, as the process is very easy the first go-around but I will need to repeat it for authenticity's sake.)
