Boot sles non graphical

How can I change the initrd to boot sles completely in terminal modus so non graphical?
I changed all-ready the menu.lst of grub and put splash to no via yast sysconfig and did mkinitrd but sles goes still into some kind of graphical modus during boot.
Where can I change this??

By adding “nomodeset” in grub, vga=normal is not enough. After nomodeset sles boots completely in textmode.
Problem solved…
