Qu'est-ce que EFI v2.31 Lenovo?Où puis-je le trouver?


1

À http://www.ubuntu.com/certification/hardware/201307-13930/, la version du bios qui est certifiée est EFI v2.31 Lenovo

Mais la dernière version UEFI disponible sur le site Web de Lenovo est la 2.25

Comment obtenir la version qui fonctionne?

The certification tool gets this version from the following command:

[ -d /sys/firmware/efi ] && cat /var/log/kern.log* | grep -m 1 -o --color=never 'EFI v.*'

I have a T430S which also returns EFI v2.31 by Lenovo.

The EFI version number that you see on the certification website (2.3.1, although that's often reported by software as 2.31) refers to the version of the EFI specification the firmware implements.

This is a bug in the certification site that we know about and will fix soon. As Sylvain said, 2.31 refers to the specification, not the version. The version we used when certifying this system was 0.21.
