I am a newbie to the Raspberry Pi. I have downloaded Debian 6-19-4-2012 and Raspiwrite and installed the OS on the SD card and installed it in the Raspberry Pi and booted it to the point that it wants a user id and a password to continue. None of the ‘suggested’ UID/Passwprd combinations available on various websites seem to work. Does anyone have a suggestion about a good UID/Pass combo, or what is going on and how to work around it? Some of the documented suggestions seem to be not useful when you are trapped in the UID/PWD loop and cannot get out and back to a command line. In newbie speak HELP!!
