Red Hat ENTERPRISE LINUX 3 - INSTALLATION GUIDE FOR IBM ESERVER ISERIES AND IBM ESERVER PSERIES Installation Manual page 49

Chapter 2. Installing Red Hat Enterprise Linux
You should now vary off your partition and configure the NWSD for running Red Hat Enterprise
Linux, rather than installing it. You should change your IPL Source to either B or *NWSSTG. If
you change it to *NWSSTG (booting off of your PPC PReP boot partition) you also need to add
IPL Parameters. Now when you vary on your NWSD it boots up to your installed system.
Note that users installing exclusively to native SCSI disks cannot boot from *NWSSTG.
Remember that the only place you can log in as root is at the console or other devices as listed in
/etc/securetty
pSeries — Completing the Installation
Do not forget to remove any diskette in the diskette drive or CD in the CD-ROM drive.
After rebooting, you must set the open firmware boot device to the disk containing your Red Hat
Enterprise Linux PReP and / partitions. To accomplish this, wait until the LED indicator says
, then press [F1] to enter the System Management Services GUI. Click on Multiboot and
E1F1
then click on Boot Sequence. Select the disk containing your Red Hat Enterprise Linux and type
1. Set the other devices as you wish, then click on Save, then Exit. Click on Exit from the main
menu to boot your new system.
After your computer's normal power-up sequence has completed, YABOOT's prompt appears,
at which you can do any of the following things:
Press [Enter] — causes YABOOT's default boot entry to be booted.
•
Select a boot label, followed by [Enter] — causes YABOOT to boot the operating system
•
corresponding to the boot label. (Press [Tab] for pSeries systems at the
list of valid boot labels.)
Do nothing — after YABOOT's timeout period, (by default, five seconds) YABOOT automat-
•
ically boots the default boot entry.
Once Red Hat Enterprise Linux has booted, one or more screens of messages should scroll by.
Eventually, a

The first time you start your Red Hat Enterprise Linux machine in run level 5 (the graphical run level),
the Setup Agent is presented, which guides you through the Red Hat Enterprise Linux configuration.
Using this tool, you can set your system time and date, install software, register your machine with
Red Hat Network, and more. The Setup Agent lets you configure your environment at the beginning,
so that you can get started using your Red Hat Enterprise Linux system quickly.
If you are not sure what to do next, we suggest you begin with the other Red Hat Enterprise Linux
manuals available online or on the Red Hat Enterprise Linux Documentation CD included with your
Red Hat Enterprise Linux product.
HTML, PDF, and RPM versions of the manuals are available on the Red Hat Enterprise Linux Docu-
mentation CD and online at http://www.redhat.com/docs/.
Note
Although this manual reflects the most current information possible, read the Red Hat Enterprise
Linux Release Notes for information that may not have been available prior to our documenta-
tion being finalized. They can be found on the Red Hat Enterprise Linux CD #1 and online at
http://www.redhat.com/docs/.
If you are a more experienced user looking for information on administration topics, you may find the
Red Hat Enterprise Linux Reference Guide to be more helpful.
