Linux: Updating the SMP kernel
Red Hat Linux
All versions of Red Hat Linux detect the new processor hardware automatically. However, to use both
processors, you might need to manually install an SMP (Symmetric Multi-Processing) kernel. See note
below.
The Red Hat box set for your distribution contains the SMP kernels (if offered) for all versions of Red Hat
Linux, or using the account login information sent with your original hardware, you can get the SMP
kernel at http://www.rhn.redhat.com.
To install an SMP kernel:
1. Obtain the SMP kernel RPM for your distribution of Red Hat Linux.
2. Install the RPM on your system as root:'rpm -ivh <smp_kernel_name.rpm>
3. Reboot your system.
4. Choose the SMP kernel in the Grub menu at startup. If your SMP kernel is not your default kernel,
modify your /etc/grub.conf file so that it is your default, if you so choose.
5. Your Red Hat Linux system is now using both of your installed processors.
NOTE: Red Hat Linux kernels, both UP and SMP, support a limited amount of physical RAM. If your
system has more than 4 GB of physical RAM installed, visit http://www.redhat.com to see if the kernel
you are running can address all of the RAM you have installed.
NOTE: If you are running a Red Hat 64 bit OS distribution, visit http://www.redhat.com to see if a
separate SMP kernel is needed to enable Symmetric Multi-Processing as the standard booting kernel for
the 64 bit distributions is both UP and SMP capable.
