driver corruption is highly unlikely, the driver doesn't write to the eeprom unless told to do so by the user. More than likely either your system is being managed by iAMT and was somehow corrupted by that firmware, or you have a hardware failure. One avenue at this point is contacting the customer support of your laptop vendor. >> if you saved a dump of your eeprom before you started writing to it, >> you can program each byte back into place using ethtool (if the >> device shows up) > > The device shows up on the PCI bus, but no network device (as the > driver refuses to continue once it detects a bad checksum).

If the MAC address check fails after that you can try bypassing that too. > A colleague has an identical machine though, could that be used with > some manual fiddling of the MAC address bytes? yes. I would start by getting the driver to load (if it will) and then doing ethtool -e on both machines and comparing results. >> If you happen to be using a LOM or >> e1000e part that is integrated with a chipset like ich8/9 it is >> likely one of the bios update(s) will upgrade/repair the eeprom >> (since on those parts the eeprom is embedded as part of the BIOS >> flash rom). > > This is a laptop, so it is most probably built in.

I don't know because you never mentioned what type of hardware you're using nor did you post an lspci -vvv ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ E1000-devel mailing list E1000-devel@lists.sourceforge.net https://lists.sourceforge.net/lists/listinfo/e1000-devel
