[lug] Why doesn't any OS see my memory?

[Ferdinand Schmid]

Yes, this is normal - on 32bit systems.  I forgot where all the memory address 
space is used - but a 32bit system can only address 4GB of RAM. Your video 
memory and other driver address space is included in that number.  3.5GB is 
what I remember as the maximum amount of usable RAM on a 32bit system.
