1- How I shut down Pluto properly pluto computer when I need to?
If it's a hybrid or media diectory, choose the 'power' button on the on-screen orbiter and click 'power off'. If it's a core, press alt+f2, login with the root username/password, and enter: halt
2-Support for Nokia 6620 phone
Please clarify what isn't working. What do you see happening? If it's a symbian series 60 phone it should work without incident. If not, please try to do a live chat before 5pm GMT (noon EST) and I can transfer you to chris who does the orbiter symbian.

http://plutohome.com/support/index.php?section=document&docID=2085-Installation of the PCI video card mentioned above
Regarding the RAID and the PCI video card, there are only 2 guys on our staff who are experts with Linux drivers issues and the kick-start cd. Likely the drivers you need aren't included on the stock cd. This happens a lot. Unfortunately they are both out on vacation this week. I'm sure you're anxious to get it working, but the rest of us aren't so knowledgeable about these issues since it's really nothing to do with Pluto and purely a Linux issue. Can we have one of them help you with this next week? Then they can do chat or a phone call. In the meantime you could poke around on the linux forums, however, since you're not a linux user you'll find it rather complicated, and it might be best to wait.
