That would be a solution, but I think what Windows do is writing it
somewhere in NVRAM for the BIOS to check at boot (at least in my Z1A).
For example, If you set the brightness to minimum under Windows, then
halt and start the computer again, the brightness is set by the BIOS to
the minimum at the very beginning.

I tried to compare the data from /dev/nvram in the two states, and
indeed there is a difference.  But /dev/nvram doesn't seem to reach all
the BIOS configuration data, since writing one of the saved data back
into /dev/nvram, somehow disabled the boot animation and set the sound
volume back to factory default (in addition to changing the default
brightness).

Has anyone else fiddled with the BIOS configuration data?
