The ADL855PC is an embedded module that is using the i855GME chipset
(the same as the Getac W130 as far as I remember).

Last I checked, the 855 port was not very good, but there's probably
nothing in the way of attempting to write a port for that laptop.

You should make sure you have some means of recovering your flash chip
back to something working, because writing a port and getting a system
booting typically takes a few tries ;)

Thanks, I`ve already ordered PLCC extractor and programmer for this
purpose, PLCC bed is not designed for in-scheme clip reprogramming
anyway. EC looks like not a big deal, though it should implement some
unique bits like HDD heater setting.
