Hi,
after install linux as second OS on my Jumper EzBook 3 PRO (v4), i’ve switched OS TYPE in CHIPSET SETTINGS to LINUX and after reboot grub start working, but i don’t have access to BIOS anymore and boot screen is dimmed out (minimum brightness).
I can’t enter setup by pressing esc or del. Keyboard not working during boot and also in GRUB. I have access to linux and i’ve tried to reboot to BIOS by command :
systemctl reboot --firmware-setup
and it works, bu still i can’t use keyboard and reset BIOS settings 🙁
Any idea how to deal with it ?
I’m thinking to clear NVRAM by dd, but i’m not what will happened ?
modprobe nvram
dd if=/dev/zero of=/dev/nvram
maybe someone tried this method before ?
