Today I was about to try write support for flashrom with the Xi 3650
BIOS and see whether it would work. The two images used for write were
not too different (the only difference was a BIOS setting letting you
choose between the on-board graphics card and an Nvidia Geforce 9600M
GT). Nonetheless it seems to have written (and erased) at least one
block of the BIOS ROM correctly.

P.S. the console screenshot:

WARNING! You seem to be running flashrom on an unsupported laptop.
Laptops, notebooks and netbooks are difficult to support and we
recommend to use the vendor flashing utility. The embedded controller
(EC) in these machines often interacts badly with flashing.
See the manpage and http://www.flashrom.org/Laptops for details.
If flash is shared with the EC, erase is guaranteed to brick your laptop
and write may brick your laptop.
Read and probe may irritate your EC and cause fan failure, backlight
failure and sudden poweroff.
You have been warned.
