Just installed Debian.. I'm not happy

[edge]

Okay..

After spending about 3 hrs in the datacenter, (I've also installed 2 new HDD's), and doing a lot of tweaking from home (SSH) I just discovered that the OS is not seening both CPU's :-(

host:~# cat /proc/cpuinfo

With the old OS on it (Fedora RC4) it was like this:

Is it hard to get the Debian install to see both CPU's, adn can I do this through a SSH connection?

uname -a is giving me
Linux host.removed4.now 2.4.27-2-386 #1 Wed Aug 17 09:33:35 UTC 2005 i686 GNU/Linux

I think you have to do this:

Give this command to find the available SMP (multiprocessor kernels):

apt-cache search kernel-image | grep smp

Choose this linux kernel for use with dual xeon:

kernel-image-2.6.8-12-em64t-p4-smp

Linux kernel install with this command:

apt-get install kernel-image-2.6.8-12-em64t-p4-smp

This commands reads the installed linux kernel:
uname -a

Remove the not necessary current kernel:

dpkg --purge --force-remove-essential kernel-image-2.6.8-2-386
(or other current kernel according the result of command uname -a)

Reboot your system.

This will give you full support for your dual xeon system with hyperthreading as well.

Congratulations!

This looks good.

Good luck with your DEBIAN SMP system !

Thanks Hans,

Only problem is that a friend helped me with it.. He installed the kernel-image-2.4.27-3-686-smp

I just asked him why he did not use the kernel-image-2.6.8-3-686-smp version..

He told me that he did not have any experience with upgrades from 2.4.x to 2.6.x (your info did help him)

Not sure if it's any different, and if it's worth risking upgrading the kernel again to 2.6.8

Thanks again for your help!

[Hans]

2.4 or 2.6 kernel...The most important is that you have full advantage of your Debian SMP system now.

I also do not have the experience with updating from 2.4 to 2.6.
At this point i can not help you.

But if you just started you with a new and empty system you can consider to start over again and install the 2.6 kernel.

You can do this with the "linux26" command after inserting the Debian CD in your drive.

Maybe not important for you but good to know is that the 2.4 kernel series do not support SATA drives.

I have also seen that you choose for a 32 bit version.
I have installed the unofficial Debian Sarge 64 bit version with the kernel-image-2.6.8-12-em64t-p4-smp.

This Dual Xeon system is up and running for months now without any problems. Very stable. So if you want to give it a try....
(I mentioned this for consideration and have a little bit more advantage of your dual XEONs)
