Dear Pieter,

thanks for the information.  Unfortunately, putting the line
hw.physmem="3G" in /boot/loader.conf as you suggested does not prevent
the system from crashing when starting X (even using "2G"), while
taking physically out the 2G memory bank  from the motherboard does.
That's a pity because this being a dual boot system, I could have left
the 4 GB of RAM in when using the other OS....   Is there any other
option that you would be aware of?

thanks again

giuseppe
