I agree that 'linux-4am5' rather sounds like the computers hostname on a factory-installed computer. If it looks like:
then it's a login prompt, and you have to enter your own user name and on the next line your password. These values must be documented somewhere in the printed booklet that came with the computer. If no such info is available, then try 'root' as user name, and use an empty password. Not sure that it works, but worth a try.
