   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

Steve,

You need to run a PAE 32-bit kernel in order to see more than 3.1 GB.

I wouldn't be too concerned about the lspci output yet.

Thanks for the help Michael, I suppose if I test the machine as much as I can before putting it in service, fingers crossed! Steve
