Naomi has been implemented with a dual-boot environment, meaning that you can either boot into a DOS session, for backward compatibility with Turpol's software; or into a Linux session, which will provide you the means to transfer your data out of the computer.
NB: There are currently no plans to reimplement Turpol's software, so this dual-boot scenario is needed for the normal operation.
At boot time you will be presented, during a few seconds, with a menu that will let you choose the right session. Turpol's DOS session is the first one, and the default option, so you don't need to do anything special. Just wait or press ENTER, and you're done.
Within seconds you'll be greeted with the C: prompt and you can continue then with the environment start-up.
To leave this session, you can either Ctrl-Alt-Del or push the reset button (if you want to reboot) or hit the power button to shutdown.
At boot time you will be presented, during a few seconds, with a menu that will let you choose the right session. Turpol's DOS session is the default one, so if you want to boot into Linux you'll need to choose one of the other options. As an observer you'll want to use the second option, the one that comes just after the DOS session. The others are only meant to be used for engineering tasks, so please don't bother trying to choose them.
After a while you'll see the typical Unix login prompt:
naomi login:
Log in as the obs user, using the password that will be provided by the support staff.
After logging in, you can access your data under the directory /mnt/driveD. You'll recognize there the same layout as in the DOS D: unit. Now, you can use scp/sftp/ftp to transfer your data to other computer (your laptop, some other machine at your institution...)
NB: this session is only meant as an aid to get your data out of the computer. To prevent data loss, /mnt/driveD is accesible in a read-only fashion.
To leave this session, press the Ctrl-Alt-Del sequence and let the system reboot. After this happens, you can switch off the computer if you're not going to use it anymore.
