tion (GRUB or LILO depending on what you have currently installed) and have updates applied.

A.4. Upgrading Packages
At this point, there is nothing left for you to do until all the packages have been upgraded or installed.
A.5. Upgrade Complete
Congratulations! Your Red Hat Enterprise Linux 4 upgrade is now complete!
The installation program prompts you to prepare your system for reboot. Remember to remove any
installation media if it is not ejected automatically upon reboot.
After your computer’s normal power-up sequence has completed, the graphical boot loader prompt
appears at which you can do any of the following things:
• Press [Enter] — causes the default boot entry to be booted.
• Select a boot label, followed by [Enter] — causes the boot loader to boot the operating system
corresponding to the boot label.
• Do nothing — after the boot loader’s timeout period, (by default, five seconds) the boot loader
automatically boots the default boot entry.
Do whatever is appropriate to boot Red Hat Enterprise Linux. One or more screens of messages should
scroll by. Eventually, a login: prompt or a GUI login screen (if you installed the X Window System
and chose to start X automatically) appears.
