Question
Centos 5.3 (trixbox) only see's 3 of my 4 gig of ram on Dell Poweredge 1850
I have installed Trixbox 2.6 on a Poweredge 1850 with 4gig of ram (all ram tests fine and can be seen in bios) its a dual Xeon 3.20ghz.
For some reason it only see's 3 of the 4 gig of ram.
I also tryed Trixbox 2.8 and it was the same.
Any Idea's?

32bit can see upto 64G just fine.
I see two issues here
- You are running kernel without PAE support, therefore You kernel can see upto 4GB-somethingMB of total memory. Please install and run PAE kernel to see all physical memory.
- If You cannot install PAE kernel, go to BIOS, and look for option describing PCI memory(hole) address start. I assume it's currently set to 3GB, You probably can set it to 3.5GB. Non-PAE kernel will only see the memory upto PCI memory mapping address.
To verify that, please post here beginning of the output from 'dmesg' command(memory mappings).
thanks for the help,
I have changed to a PAE Kernel,
2.6.18-128.1.10.el5.centos
but still no luck, and in the BIOS there does not seem to be any option for PCI memory(hole) (http://dcse.dell.com/ifr/

here begins BIOS data - it's 3GB, the 4th usable gig is at
> BIOS-e820: 0000000100000000 - 0000000140000000 (usable)
That's exactly at 4GB - unavailable for non-PAE kernel.
So You can see it's BIOS who remapped 4th gig to space above 4GB rendering it unavailabe for non-PAE kernel.
> Warning only 4GB will be used.

That's only the confirmation.
So we back to my first post - either PAE kernel, or force BIOS to move the PCI hole to 3.5GB (linux will see 3.5GB then). If the latter is unavailable, then either 3GB only or PAE kernel.
Oh, 64bit kernel will also do. You can install the 64bit kernel while still running 32bit userland.

Is your CentOS distro a 32-bit distribution or 64-bit? Run uname -a and look if x64 is in there anywhere?
