Changing GRUB

[Linux Newbie]

When I turn my system on GRUB displays the message "Press any key to enter 
the menu" then a couple of blank lines and then the default OS and countdown 
timer.  I would like to remove the "Press any key..." and two blank lines 
and display just the default OS and countdown timer.  I looked in the 
grub.conf file and it's not there.  Does anyone know how to remove these 
three lines?
