phnxdeco doesn't read the flash chip, it disassembles the bios file (the
updated one you handed it). This page might help:
http://www.bootdisk.com/pendrive.htm. I've also been known to hack up a
windows 98se CD to update a laptop BIOS (remove all windows install files,
copy BIOS flash tool + BIOS update).

As far as flashrom is concerned, we'd need to first know your laptop's
chipset (lspci should suffice). The flash chip also probably has some other
chips blocking off access to it, perhaps the southbridge or embedded
controller, there's a couple ways to find out that info but I'm not an
expert on finding or poking them to get access.
