the chip was directly connected (desoldered from notebook) with a cable adapter of 3-5cm.. can you tell me an "Intel network card" valid to find?
thanks and congratulations for the work done! 2013/9/27 Carl-Daniel Hailfinger <[email protected]> > Hello Fabio, > > Am 25.09.2013 15:01 schrieb Fabio: > > hello, I'm trying to retrieve a notebook with SST25VF040B, but is not > > recognized by flashrom.
