How the Linux system displays the multicore mode

At the time of installation, the customer did not choose to install KERNEL-SMP, the system will be installed by default as a single processor core, users can upgrade the system by adding a multiprocessor core module.

Specific steps:

1, start red Hat Linux as 4, log in as root, enter the character interface.

2, Decompression kernel-smp-2.2.14-5.0.i386.rpm package, (method many can enter the CD-ROM drive directly decompression, also can also copy the CD-ROM contents to the shared directory)

#rpm--install kernel-smp-2.2.14-5.0.i386.rpm, load Multiprocessor (SMP) modules.

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 multiple processor startup options, such as

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, reboot the machine, after "boot:" appears, type "SMP" enter, into the multiprocessor core.
