9.5. How do I change the Red Hat Linux logo bootup screen image?

Redhat uses xbanner to display its logo, so to disable it, just comment out the line calling xbanner from the configuration file xdm reads, which is /etc/X11/xdm/Xsetup_0 (may vary). If you want something else to run there, put it in instead, for example:

 /opt/kde/bin/kdmdesktop
