Muchas veces necesitamos conocer información del BIOS, pero no queremos reiniciar nuestro sistema operativo GNU/Linux, así que queremos resolver de alguna manera. Les voy a mostrar como resolver por medio de la terminal.
Obs:
- Utilizo Ubuntu 18.04 LTS Beaver Bionic de 64 bits.
Entramos a la terminal para obtener la versión del BIOS:
sudo dmidecode -s bios-version
Sale por pantalla:
6LCN22WW(V1.08)
Toda la información relacionada al BIOS:
sudo dmidecode --type bios
Sale por pantalla:
