It will be necessary to prepare the ROM with the own MAC address or just use
the flash script to update the BIOS?
Anyway these news sounds very good for me:
256MiB VRAM allocated on GM45 (X200, T400, T500, R400) instead of 32MiB. This
is an improvement over both Lenovo BIOS and Libreboot 20150518, allowing
video decoding at 1080p to be smoother. (thanks Arthur Heymans) To clarify,
GM45 video performance in libreboot 20160818 is better than on the original
BIOS and the previous libreboot release.
Massively improved GRUB configuration, making it easier to boot more
encrypted systems automatically, and generally a more useful menu for booting
the system (thanks go to Klemens Nanni of the autoboot project). Libreboot
now uses the grub.cfg provided by the installed GNU/Linux distribution
automatically, if present, switching to that configuration. This is done
across many partitions, where libreboot actively searches for a configuration
file (also on LVM volumes and encrypted volumes). This should make libreboot
more easy to use for non-technical users, without having to modify the GRUB
configuration used in libreboot.
