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:

Calibrating delay loop... OK. ======================================================================== 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.
