I install centos 5 on a HD while it is in a Compaq with 256Mb

not quite all 256Mb used.
Then I move the HD to a decTOP with 512Mb memory. I am running
non-graphics (init 3). I ssh into the unit and top reports not quite
all of that used.....
So what ate up more than 256Mb memory (X is not running)?
Perhaps there is something I did not clean up properly wrt the move.
Have you done any I/O on the system? The memory could be in use by
buffers. Please post the contents of /proc/meminfo. Your real free
memory should be the sum of MemFree + Buffers + Cached.
