Hello,

Sorry for my bad english...

I have installed the FC9 on a box to do an http server (intranet only...).

My box is
CPU INTEL CORE QUAD Q6600 (2.2GHz)
4 X 2Go DDR2 667 KINGSTON
VIDEO GEFORCE 8500GT
MOTHERBOARD ASUS P5K-SE

The install is OK, and it work so fine :D !
But, when i look the system monitor or file /proc/meminfo i see :

32-bit or 64-bit Fedora? I can't confirm it right now, but if you're using regular 32-bit Fedora, my guess is that the stock Fedora x86 kernel must not have Physical Address Extension compiled in (meaning the kernel can only address some of the memory).
http://en.wikipedia.org/wiki/Physical_Address_Extension

You either need to recompile the kernel with PAE support or install Fedora x86_64 (I'd personally do the latter as it's more efficient to run 4GB+ of memory on 64-bit oeprating systems than 32-bit operating systems with PAE duct-tape.

There may be a PAE kernel compiled and distributed from the Fedora repositories, so poke around there.

(Also, depending on the load on the intranet, you probably won't need all 8GB to serve HTTP!)

I can confirm this. Just yum install kernel-PAE.

Yup, I just fired up my Fedora box and it's in there.

So do


su -
yum install kernel-PAE
reboot


Then make sure you select the newest version of the PAE kernel at GRUB (might want to edit /boot/grub/menu.lst to make sure it defaults to the kernel you want, but yum should handle that).

It is exact, i use a 32-bit version.
For the 8Go, i think it's too for an HTTP server, but it is for me a good experience of installation and to do some tests
for validate a production box. Our actualy box how is use for the HTTP server (FC7) is not stable and lost some of
there services.

I go to use your advices....

Thanks for your answer.

I am very disappointed.
I did not get proper installation of the FC9 ! The kernel-PAE refuses to work on the motherboard whith 8Go of RAM but works very well on a motherboard that does not work with more than 4Go ! Very funny.
The FC9 64bit cant work whith my RAID adapter...
One thing is sure, tha's the problem for updates whth yum or the graphical update. It's presents at every installation !
In short, a return to lower equipment with a previous version of FC !
Quel dommage !
