So my question is this, my brother in law gave me an old dell and I'm thinking about making it a homemade NASbox. When I tried to boot up the computer it has a password on it which I do not have and neither does my brother (he works for a college and the computer was one from a lab or something). I am wondering if I try to install FreeNAS, will I need to find that password, or does freenas act as an OS so it won't matter. Sorry if this is a dumb question, I'm new to doing much over just using computers for general everyday stuff. And help would be appreciated.
