@Vaelatern we found an issue in the bios where when rebooting from linux you may not be able to enter the bios menu when the keyboard is in media key mode after rebooting from linux. We are fixing this in our next bios update.
You can try a few things.
- Try Fn+Esc to toggle the function keys to function key mode, and then reboot and try to enter the bios.
- Try Fn+F12 while the system is booting to enter the boot menu/ or Fn+F2 to enter the bios.
In the initial bios we shipped with, we force the function keys to function key mode while in the bios boot process. However when the system boots to windows or linux, the OS sends the bios a message to indicate the OS is booted and SCI is enabled.
However linux does not disable SCI on shutdown/reboot so then media key mode will be stuck enabled, and you will not be able to enter the bios.
