2, unzip the kernel-smp-2.2.14-5.0.i386.rpm package, a lot of methods can enter the drive directly decompress, you can also copy the drive to the shared directory)
# Rpm -- install kernel-smp-2.2.14-5.0.i386.rpm, load multi-processor smp) module.

3. # mkinitrd-v-f/boot/initrd-2.2.14-5.0smp.img 2.2.14-5.0smp, create the initialization program.

4. # vi/etc/lilo. conf, add the multi-processor startup option, for example

Image =/boot/vmlinuz-2.2.14-5.0smp
Label = smp
Initrd =/boot/initrd-2.2.14-5.0smp.img
Read-only
Root =/dev/sda2

5. # lilo-v: restart the machine. After "boot:" appears, type "smp" and press enter to enter the multi-processor core.
