Libreboot is a distribution of coreboot, which is basically identical to the latter, except for the fact that all proprietary blobs are removed in order to obtain a fully FOSS firmware that initializes hardware and boots the operating system. Despite the controversy, if you are at all interested in keeping/expanding your freedoms, then you should consider using Libreboot. However there is one major problem; Libreboot is only possible on a few different systems (thanks Intel).
In September 2016, Libreboot's lead maintainer (a transgender) started accusing the FSF of having fired someone because of transgender-related issues. FSF denied these allegations. This maintainer then tried to remove Libreboot from the GNU but that wasn't a decision they were actually capable of making.
In January 2017, Richard Stallman released Libreboot from the GNU.
Then in April 2017, Libreboot removed the accusations and the lead maintainer apologized. The entire project was also transferred to another contributor. 3 weeks later they reapplied to be a part of GNU.
Check your hardware
Libreboot supports only a small subset of hardware on the market. A complete list is available on the Libreboot website, but some are easier to work with than others. For example, you can install Libreboot on a Thinkpad X60 notebook entirely via software means.
You'll also notice that most the supported devices are at least a decade old. This is because [modern hardware has severe security issues]. Old hardware does too, but Libreboot is able to overcome it.
Now that you've realized that your current laptop doesn't support Libreboot, you're probably wondering what you should get instead. Personally, I would recommend the Thinkpad X200 notebook. If you're lucky, you can buy one off Ebay for about $100 USD if you're in the United States. Libreboot also supports the X200s and X200 Tablet models, but flashing Libreboot onto either of those is somewhat more difficult.
Flashing your hardware
For any device, there are basically three steps:
- Taking apart and wiring up your target device
- Copying the current ROM off the flash chip
- Overwriting the chip with Libreboot
The first step is best followed by a visual reference and varies significantly depending on the device, so you should search online for a video specific to your hardware.
You will need a program called "flashrom", which is probably available in your Linux distribution's package repositories.
Flashrom is a general-purpose flash chip programming tool. You'll be using the following flags for this installation process:
- -p <device> - specifies the (hardware) programmer device you will use to control your flash chip. If you're using a Raspberry Pi or similar single-board computer, the device name will be "linux_spi". You can check the program's manual page for a list of every supported device.
- -r <filename> - orders flashrom to write the contents of the flash chip to the specified file.
- -w <filename> - overwrites the ROM on the flash chip with the contents of the specified file. This is where you're most likely to brick the device.
- -c <chipset> - specifies the chipset of the flash chip you're writing to. This should be printed on the chip.
You'll start with the command
sudo flashrom -p <device> -r romread1.rom
You may also need to specify the chipset with the "-c" flag.
It is recommended to read the ROM multiple times, and then compare the reads to make sure they're identical. Once you've read the ROM to three different files, you can compare their hashes to make sure they're the same.
Once you've gotten three identical reads, proceed by overwriting the ROM. Make sure you've selected the correct ROM image for Libreboot, and then run this command
sudo flashrom -p <device> -w libreboot.rom
If everything works out well, flashrom will write the new ROM, attempt to verify it, and then exit with a message along the lines of "Flash verified!".
If you've gotten this far, then you should now disconnect everything from the target device and turn it on (with or without putting it completely back together). If everything worked, your screen will turn on to show a GRUB boot menu, with a background image of a penguin embracing a wildebeest. Now you just need to install an operating system.
