Question Linux with Two Kernels

Dear Friends ,

Recently I have to install RHEL 4 into HP Brand pc .When I have to install RHEL4 into it I get two Kernel Like the following :

Red Hat Enterprise Linux WS (2.6.9-5.ELsmp)
root (hd0,6)kernel /boot/vmlinuz-2.6.9-5.ELsmp ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.9-5.ELsmp.img

Red Hat Enterprise Linux WS-up (2.6.9-5.EL)
root (hd0,6)kernel /boot/vmlinuz-2.6.9-5.EL ro root=LABEL=/ rhgb quiet
initrd /boot/initrd-2.6.9-5.EL.img

I don't understand why these two Kernel Version show into it ? Here I mention that in non-brand pc I found , it shows just One kernel ? Can anyone plz explain me ...why it shows two(2) kernel and what is the meaning of these (Elsmp and smp ?)

The smp kernel has symmetric multiprocessing enabled. Use it if you have a dual core or dual processor machine.
