No more than 1GB of RAM memory detected... but I have 2GB of RAM installed

Hello,

	I have a Server with 2GB of RAM installed, but Debian Sarge with:

----------------------------------------------------------------------
#cat /etc/debian_version
3.1
#uname -a
         2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux
----------------------------------------------------------------------

	Only reports

----------------------------------------------------------------------
#free -m
                 total       used       free     shared    buffers
cached
Mem:           884        537        347
----------------------------------------------------------------------


How can I tell (to the kernel) that my system memory is 2GB, so it can see
all my memory and use it?


Thanks in advance.


Pd. I'm sorry for my bad English.
