Chances are good to get coreboot running on this laptop, its components
seem to be mostly supported by coreboot. However, the chance of getting
everything working on the first try are zero. The chances to get the
system at least to boot on the first try and always keep the system in a
working, updatable state are almost zero, too. So if you attempt to port
coreboot to this machine, you will need to create some kind of recovery
mechanism. You could solder a socket to the mainboard, or a plug to
reflash the machine externally.

However, to get started, I suggest that you find out what flash chip you
have on the board, so you can determine what recovery mechanism is
suitable. (The flashrom utility from www.flashrom.org will help you with

Also, a dump of superiotool -ed will help you a lot. Does the machine
have a serial port?


The machine has no serial port. I think it's a socketed bios(from the pics of the disassembly tech manual). However I have to disassemble everything in order to acess the BIOS
Is there a way to plug a chip that has a wire coming to the outside to a machine that contains or  the BIOS chip or and emulation of one?
I'll do all the dumps, etc and post here again.
