This is a complete list of steps I went through to configure my N770 in case I have to go through them again. Since I had previously messed the settings up. I am starting with a reflash to the latest version.
* Follow these instructions to copy the installation to a 2GB MMC card I have installed and boot from that instead. This retains the original configuration in case I need to revert to it, provides more diskspace and is reported to run faster.
