redhat7.2 question



Dear CCL'ers
 probably somebody can help me with a bit of know-how.
 During instalation of redhat 7.2 I've choose to login
 in "old&good" text modus and it was what I've seen after
 first restart. For unknown reason during the 2nd start
 Linux has loaded graphical login. Can somebody tell me
 how to make redhat not to load gdm on the start-up?
 MfG
