John,
I believe, like in Windows, you need to have specific support for High
Memory Architecture (HMA) when using Intel 32-bit Processors, which is
what I believe is in your Compaq Proliant.
You will likely have to compile a custom Linux Kernel to support that
High Memory Architecture. Unfortunately, I cannot say for sure as I have
never had the opportunity to work with such equipment, I have only read
about such hardware.
I believe you could get an answer as to how to configure a kernel for
your HMA equipment on a kernel mailing list.

Subject: Max amount of RAM in 7.2 question
Greetings -
I've scoured Google and redhat.com most of the morning for a specific
answer, but haven't found it. Hopefully someone here will have it.
I have a Compaq ProLiant server with RH 7.2 SMP (2.4.9-31smp kernel). Up
until this morning, it had 1.25 GB of RAM. This morning I installed 6 GB
RAM, replacing the existing 1.25 GB. The hardware supports 6 GB, and 6
GB
shows up fine in the BIOS POST.
However, dmesg, /proc/meminfo, and "free -m" shows that only 4 GB was
picked
up when the server was restarted.
Is 4 GB a hard maximum limit for 7.2? Is there a hard maximum limit, and
if
so, what is it?
I did find something on redhat.com that said I could use "mem=XXM" at
boot
to tell the kernel that there is 6 GB there and not just 4. Is that
correct? I would pass "mem=6144M" to the kernel at boot?
