32bit OS on 64Bit Hardware...

[Frank, Ryan W]

Hello all!
 
I am trying to build a DL-385 with AS 3.0 Update 7 32bit... The
developer specified he wanted the 32bit os... Anywho.. the box posts
with 8gb of RAM.  During the boot process I see the following message:

May 31 15:22:37 cltrsklccs01 kernel: Warning only 4GB will be used.
May 31 15:22:37 cltrsklccs01 kernel: Use a PAE enabled kernel.
May 31 15:22:37 cltrsklccs01 kernel: 3200MB HIGHMEM available.
May 31 15:22:37 cltrsklccs01 kernel: 896MB LOWMEM available.
 
When the OS comes up I only see 4gb of RAM.   I am using the SMP kernel
(should support 8gb), and as far as I can tell PAE is enabled... Checked
in /proc/cpuinfo... I have even tried specifying mem=8192M on the kernel
line in grub.conf... still no luck...
 
I *believe* the 32bit OS will not see the additional RAM, I am just
looking for any information that could point me to why so I can explain
to the developers...
