dmidecode

[Tim Wunder]

Netllama mentioned the dmidecode command on another thread, so I figured I'd 
run it to see what it does. It gave me this curious (to me) output:
# dmidecode       
...

Well, I happen to know I only have 384 MB RAM in this system, but this output 
seems to be telling me I have 512 MB more than that. 

Why?

/me googles dmidecode in the meanwhile...
