You are going to have to accept that you are never going to get all 4gb
running a 32bit install due to the limitations of using 32bit where things
need to be reserved in the 4gb which is not the case using 64bit where you
see the whole 4gb in use. I know with my machine if I boot a Knoppix Live CD
(32bit) I only see around 3.3gb useable if I use my normal Debian install
(64bit) I get the whole 4gb like below.
>$ free
total used free shared buffers cached
Mem: 4052156 4023220 28936 0 52160 1714740
-/+ buffers/cache: 2256320 1795836
Swap: 1052216 88 1052128
If you want then you can read all the gory details as to why you cannot get
the entire 4gb using 32bit in the many thousands of hits in the search below
most of the time talking about windows but the same BIOS/reserved issues are
present if using GNU/Linux. BTW if you did install 8gb in your machine you
will still not get the entire eight as well.
