The default runlevel is defined in /etc/inittab

Default runlevel. The runlevels used by RHS are:
0 - halt (Do NOT set initdefault to this)
1 - Single user mode
2 - Multiuser, without NFS (The same as 3, if you do not have networking)
3 - Full multiuser mode
4 - unused
5 - X11
6 - reboot (Do NOT set initdefault to this)

So,If you want to always boot to the text-only mode,edit "/etc/inittab" and change "id:5:initdefault:" to "id:3:initdefault:"
