Hi all,

How do you know our BIOS name (Seabios/Coreboot/Libreboot) and version?

btw if I hit F2 during boot, then I get GNU Grub 2.02.

Thank you.

Thank you.

Because of the output of this I wanted to update coreboot and did everything in the "rookie guide lesson 1" [1], restarted, and there was still the same output in $sudo dmidecode | less.
They have no regular forum, just a bug tracker.
Does anybody have a clue?

With "did everything" I mean that I followed all the steps on that page.
I'm trying to update the coreboot on my Trisquel laptop.

The laptop came with libreboot, as I ordered back then. But later the salesman I bought it from rethought his position about libreboot: coreboot comes with new updates every six months and he thought of libreboot as a "dead project", not expecting new updates as the maintainer is busy with personal occupations, so in his opinion coreboot would be the safer choice. So he grabbed my laptop on a Linux event and said he would provide a necessary update for free. He unpacked some hardware and went his way in some corner while I was having coffee and talked with a fellow Dutch Free Software enthusiast. Later the laptop salesman went out of business so I'm now on my own.
