Can anyone tell me how to read this, please? I know it says it sees 4GB, but what does the system really see for my max RAM? I have two 2-GB sticks installed since I wanted the max RAM possible for VM use. I understand I shouldn't get 4GB max, but these numbers seem low to me (cause I don't know how to read them properly... Like, what do I add together to get the amount the OS sees?). Thank you!
