Please read about PureBoot here: https://puri.sm/faq/#faq-pureboot

If you do not have a Librem Key, choose just coreboot (option 1).

Thanks. 2 more newbie q…

Where is the coreboot-heads rom file after the update to copy to the USB?

I imagine the last step to the update is the flash the room using the .ROM file?

I do not understand, how are you updating? Via script from puri.sm/coreboot ?

5

I’m updating via the script.
The last step says:

"Injecting serial number into firmware image

You may now copy the coreboot update file to USB for updating via Heads."

Trouble is i don’t know where the .rom is to copy to the USB?

Found it. its in user/updates/firmware

Wait, so you are already running PureBoot firmware, not a plain coreboot?

8

Yes, running Pureboot on the most recent 13" Librem.

This was a critical piece of information that we needed. :slight_smile:

Yes, now copy the resulting .ROM file to a USB drive, and reboot your computer. Then follow https://docs.puri.sm/PureBoot/GettingStarted.html#updating-pureboot-firmware to update.

Just curious, is it possible to order a Librem Key when preparing to flash the L5?

Sure, but the Librem Key is only suggested for PureBoot and its variants. The Librem 5 does not use PureBoot.

The Librem 5 doesn’t use Coreboot either.

Bottom line is that the Librem 5 does not (yet?) offer the integrity functionality that Pureboot + Librem Key offers and if and when that is offered for the Librem 5 we don’t know what technology it will use.

You can get a small part of the functionality of the Librem Key through use of an OpenPGP card in your Librem 5.
