Olá todos,
estou (tentando) configurar uns servidores....

Linux debian 2.6.18-5-686 #1 SMP Fri Jun 1 00:47:00 UTC 2007 i686 GNU/Linux
recompilei o kernel, e verifiquei.. a opção de 4GB de memória está marcada.
Linux debian 2.6.22.6-custon #1 SMP Wed Sep 5 07:46:43 BRT 2007 i686 GNU/Linux
pesquisei no google, mas não achei nada que funcionasse.

mais abaixo do log do boot tem:

mesmo com os logs, não consegui determinar o motivo de deixar disponível apenas 2,5 gb.
se alguém puder me informar onde estão errando fico grato,
