On this server I have: CentOS release 4.6 (Final)
In the discussion at the centos site that you mention it seems more of a
problem with Centos 5.
http://www.centos.org:80/modules/newbb/viewtopic.php?topic_id=8457
On my servers when Lilo accidentally puts a non-smp kernel in place, then I
only see 3 gigs.
So 2.6.9-67.0.7.ELsmp shows the full ram but 2.6.9-67.0.7.EL does not.
According to:
http://www.linuxtopia.org/online_books/centos_linux_guides/centos_enterprise_linux_sysadmin_guide/ch-kernel.html
kernel-smp - Contains the kernel for multi-processor systems. The following
are the key features:
a.. Multi-processor support
b.. Support for more than 4 GB of RAM (up to 16 GB for x86)
c.. PAE (Physical Address Extension) or 3 level paging on x86 processors
that support PAE
