CentOS - Apr 2010 - 'p' in boot selector & going into single-user

On boot, when I hit the F12 key to bring up the boot menu, the screen
displays the various kernels and other boot options.  In the text below
this menu it says I can hit 'p' to bring up a menu with other options.
I've done this with the last two boot-ups and no other menu or options
appear.  Is something missing?  (I also tried Alt-p, Shift-p, Ctrl-p and
a few other keys and there's no change onscreen.)


I'd like to know also how to select single user mode, but haven't found
a way to do that.

Thanks much.

When you get to the grub menu, hit 'e' at the kernel, then arrow down
one
to the line beginning with "kernel", and hit 'e' again. At the
end of the
line, add the letter s, then follow the directions for getting out of edit
mode, and hit the letter b for boot.

For single user mode, edit the kernel line and add a ' 1' or
'single' to
the end of it, then boot it.
