Updated my SEABIOS + Coreboot firmware - 2 times.
First time, it was a little unstable - worst of it was that the opportunity to choose which OS to boot flashed by - and I had to hit ESC about every 1 sec to catch this and choose.
Second time - just did this today…
I am now running this:
Purism Librem Mini v2/Librem Mini v2, BIOS 4.22.01-Purism-1 02/07/2024
Much much better - nice white on blue grub boot choice menu.
I highly recommend this firmware update.
I acquired it from here: librem_mini_v2/coreboot-librem_mini_v2-4.22.01-Purism-1.rom.gz · master · firmware / releases · GitLab
