I have an OES SP3 server running on a SMP Dell PowerEdge 2550. The
system boots up fine, however it appears that Linux isn't using all of
it's 1 gig of available physical RAM.

See below:

ServerA:~ # free -m
total used free shared buffers cached
Mem: 1009 313 696 0 30 168
-/+ buffers/cache: 115 894
Swap: 511 5 506

....You'll notice the "used" column only shows its using 313 RAM. Normally
the "used" amount should be much closer to "total" as Linux tries to use
all of its available memory at all times.

Any idea what could be stopping Linux from using the other ~700 megs of
