added 2GB of ram.
at bios level I see 3GB and it's right, but
if i run free at command line, I've got the
old quantity of mem (1GB).
There some step I missed ?
Thanks a lot
Francisco
Solved! Go to Solution.

Solutionyour Kernel might not support that much memory.
In the toplevel of your source tree the follwoing command might help
grep GB .config
The file also might be loacted in your /boot
together with the Kernel and named slightly different (like vmlinuz.config).
If you find something like
CONFIG_1GB=y
your Kernel does not support "large" memory and you either need to recompile or download another Kernel from RedHat.
Greetings, Martin

Re: Linux RedHat 7.2 - Adding Memory -
in your kernel (have a look in your .config file).
Also check to first page of dmesg like follows.
#dmesg | more
there on the first page of dmesg you should see what the system say's it see and if there are some error's reported.
Hope it help you

or compile your own.
As has been said, it has to do with the kernel memory flag.
Most machines don't have such large amounts of memory, so by default RH use a kernel tweaked for smaller memory amounts.

Re: Linux RedHat 7.2 - Adding Memory -
As my collegue said, the standard kernel shipped with RH7.2 is compiled without the bigmem options.
First, you have to upgrade your kernel with either a 'smp' or a 'enterprise' version.
Download the kernel binaries here :
ftp://fr2.rpmfind.net/linux/redhat/updates/7.2/en/os/i686/
Good luck.

Re: Linux RedHat 7.2 - Adding Memory -
I'm now a new questions regarding kernel update:
I've downloaded
kernel-bigmem-2.4.20-24.7.i686.rpm
I can't find the corresponding
kernel-headers and kernel-utils.
How can I know the right version to use
of these rpm?
thanks again

Re: Linux RedHat 7.2 - Adding Memory -
The only things in the kernel packages are the kernel's (and related files) themselves.
Install it (not upgrade or freshen), and away you go.
