I. Usage Statement
==================

The downloadable XL Fortran Advanced Edition V9.1 for Linux Run-Time
Environment Component is not warranted. This Program contains run-time
components that is to be used only by applications developed with
IBM XL Fortran Advanced Edition for Linux. You may not use any part
of this Program with any other application or program. For detailed
terms and conditions, please refer to the LicenseAgreement.txt and
LicenseInformation.txt. 


II. Prerequisites
=================

IBM XL Fortran Advanced Edition V9.1 for Linux Run-Time Environment
Component is compatible with the following operating systems:

-	Red Hat Enterprise Linux AS for POWER V3 (RHEL 3), Update 3
-	SUSE LINUX Enterprise Server 9 for POWER (SLES 9)


III. Installation Instructions
==============================

To install the IBM XL Fortran Advanced Edition V9.1 for Linux Run-Time
Environment Component, complete the following steps:

1. Download, unzip (with gunzip), and untar the rpm packages.

example:   
	gunzip xlf.rte.91.sles9.mmmYYYY.update.tar.gz
	tar -xvf xlf.rte.91.sles9.mmmYYYY.update.tar

       where:              
              mmm  is the month
              YYYY is the year

2. You must uninstall any previous versions of the rpms already
installed on your system.    Do not uninstall rpms that you are
not upgrading.

To uninstall an rpm package, use the following command:

	rpm -e <package name> 

You must uninstall rpm packages in the following order:

	rpm -e xlf.rte-x.x.x-x
	rpm -e xlf.msg.rte-x.x.x-x
	rpm -e xlsmp.rte-1.x.x-x
	rpm -e xlsmp.msg.rte-1.x.x-x

where:

x	refers to the level of the rpm package installed on your system.
	To determine the level, use the following commands:
	
	rpm -q xlf.rte
	rpm -q xlf.msg.rte
	rpm -q xlsmp.rte
	rpm -q xlsmp.msg.rte

In cases where an rpm package is required by other installed packages,
as it occurs if you have XL C/C++ Advanced Edition V7.0 for Linux
installed on the same system, the package may not uninstall.
To upgrade a shared package, specify the --nodeps option with your
rpm command. For example:

	rpm -e --nodeps xlsmp.rte.1.5.0-0


3. Install the packages using the following command:

	rpm -ivh <package name>

You must install the rpm packages in the following order, dependent on 
your operating system:

SLES 9

	rpm -ivh xlsmp.msg.rte-1.5.x-x.ppc64.rpm
	rpm -ivh xlsmp.rte-1.5.x-x.ppc64.rpm
	rpm -ivh xlf.msg.rte-9.1.x-x.ppc64.rpm
	rpm -ivh xlf.rte-9.1.x-x.ppc64.rpm

RHEL 3

	rpm -ivh xlsmp.msg.rte-1.5.x-x.ppc64pseries.rpm
	rpm -ivh xlsmp.rte-1.5.x-x.ppc64pseries.rpm
	rpm -ivh xlf.msg.rte-9.1.x-x.ppc64pseries.rpm
	rpm -ivh xlf.rte-9.1.x-x.ppc64pseries.rpm

where x represents the version number.


IV. Deinstallation Instructions
===============================

If you do not require the XL Fortran Advanced Edition V9.1 for Linux
Run-Time Environment Component, uninstall the component as follows:

	rpm -e xlf.rte-9.1.x-x
	rpm -e xlf.msg.rte-9.1.x-x
	rpm -e xlsmp.rte-1.5.x-x
	rpm -e xlsmp.msg.rte-1.5.x-x

where x represents the version number.
