Hi Guys, In a bit of a pickle.. Is anyone running the latest "Centos 5.9" or earlier version with an Intel X79 based motherboard. I have a server which needs the motherboard replacing asap and I have a spare "Sabertooth X79". I have a machine with a "Sabertooth X79" motherboard to test on which boots up fine on on "Centos 5.9 i386" image from the troubled server. However the output from "lspci" (see below) seems far less descriptive than you normally see in "Centos 5" or "Centos 6". I am just a bit worried that this might imply lack of support. I do not need audio/firewire.. but need the essential to work memory, sata etc. Also I thought "i386" installs could not see more than 3 and a bit Gigs of ram? The test machine has 32G and meminfo shows
MemTotal: 3574676 kB MemFree: 3146556 kB
I would really appreciate any advice. Regards Steve
e.g. The output from "Sabertooth X79" and "Centos 5.9" gives

Are you using a PAE kernel? If you want access to the additional memory above ~3.5GB you'll need a PAE kernel.
CentOS 5 i386 has both non-PAE and PAE kernels. CentOS 6 i386 only has kernels with PAE support.
Take a peek at the output from uname to find out what kernel you're running.
I would really appreciate any advice. Regards Steve

Thanks for the reply, I have included the "lspci" output from the new board running "el6". I am sure that the kernel is not PAE but can not check as I am at home and the test machine is turned off at work. I did however run a yum update on the machine so I am wondering if that would notice the memory was sufficient to benefit from a PAE kernel? I will pop into work later to day and post the running kernel.

It is better that you provide output of "lspci -nn" so DeviceID's are also listed, to be searched for kernel modules, device drivers.
Like: 00:14.5 USB controller [0c03]: Advanced Micro Devices [AMD] nee ATI SB7x0/SB8x0/SB9x0 USB OHCI2 Controller [1002:4399]
Device ID in this case is: 1002:4399
So you can go to http://elrepo.org/tiki/DeviceIDs and check if there are kmod packages to provide the driver for that device.
Also worth noting is that ElRepo also provides 3.0.x kernels for CentOS 5.x that should be kABI/ABI compatible. Latest is 3.0.93.

I have included the "lspci -nn" output below. The X79 board and Centos 5.9 seem to be fine.. It boots, the SATA disk seems to work as expected it just would be good to actually clarify the system is safe to use.
Ok here is the memory and kernel information it doesn't state PAE yet it seems to recognise the 32G.

Btw., if you want to see if all device have kernel modules, use output of "lspci -nnk".

[1] I include the output of "lspci -nnk" below.. problem is I am not sure the best way to interpret the information. Can I assume that if the kernel picks a driver for a device i.e. the "ATA controller [0106]: Device [1b4b:9130]" then this is properly supported by the kernel *or* could it be it picks a generic driver that might / might not work properly? I hope it will work properly being an enterprise distribution?
[2] I am still confused how given the kernel reports as being
2.6.18-348.12.1.el5 #1 SMP
and not a PAE kernel.. Why am I seeing

As I recall, as of EL6 they no longer ship separate SMP and/or PAE kernels for i386. They're all SMP- and PAE-enabled out-of-the-box.
I just looked in http://mirror.centos.org/centos-6/6/os/i386/Packages/ and there is ONLY one kernel package provided. There are kernel-debug, -header, -firmware, -devel and -doc packages, but no -SMP or -PAE packages.
I believe it stated as much in the EL6 release notes, at least for the initial release. But I've slept since then...

As I recall, as of EL6 they no longer ship separate SMP and/or PAE kernels for i386. They're all SMP- and PAE-enabled out-of-the-box.

Jay, he uses CentOS 5.9! not 6.x.

Btw., if you want to see if all device have kernel modules, use output of "lspci -nnk".
[1] I include the output of "lspci -nnk" below.. problem is I am not sure the best way to interpret the information. Can I assume that if the kernel picks a driver for a device i.e. the "ATA controller [0106]: Device [1b4b:9130]" then this is properly supported by the kernel *or* could it be it picks a generic driver that might / might not work properly? I hope it will work properly being an enterprise distribution?

[1] I can not help you with explanation about usage of kernel modules, but I am sure somebody will jump in.
[2] "yum install kernel-PAE" will install PAE enabled kernel and after reboot you should access full memory.

free just outputs in kilobytes unless you pass it options.
So you're only looking at 3.5 GB of memory with a non-PAE kernel in CentOS 5 based on your numbers. Go PAE and you'll be able to utilize the 32GB of RAM.

Doh.. thanks Mike .. consequence of working through the night I expect! Ok now just to decide if it is safe to run "centos 5" on the x79 motherboard.
