Without changing the /boot/grub/grub.conf:
When you start CentOS/PC, press down or up error (repeatedly until menu
for kernel/system selection appears). Then select desired kernel.
With changing the /boot/grub/grub.conf, but manual selection:
In /boot/grub/grub.conf change:
disable hiding of the menu:
#hiddenmenu
Optionally change
timeout=10
with larger number (number is in seconds).
With changing the /boot/grub/grub.conf, and auto-selection:
Change:
default=0
to match entry you wish to boot by default
0 = first kernel, on top
1 = second
....
