<H3>Installing XFS from the Red Hat RPM packages</H3>
<A href="ftp://oss.sgi.com/projects/xfs/download/PreRelease-0.9/RH7.0-SGI-XFS_PR/RedHat/RPMS/">
Red Hat RPMs</A> have been provided for Intel architectures.  
Because these contain a Linux 2.4 kernel, please consult the 
<A href="http://cyberbuzz.gatech.edu/kaboom/linux/Changes-2.4/changes24.html">
Linux-2.4 Changes</A> document for minimum system software necessary to
support a 2.4 Linux kernel, and where to obtain those upgrades.
Red Hat 6.2 users in particular should pay close attention here, as 
Red Hat 6.2 is not as "2.4.0-ready" as Red Hat 7.0.<P>

These RPMs were built on a Red Hat 7.0 system, but they should work on a 6.2 system
as well, with the RPM package itself upgraded to 3.0.5 or higher.<P>

On all Red Hat systems, you should also upgrade these packages for XFS support:
<UL>
<LI>devfsd</LI>
<LI>modutils</LI>
<LI>mkinitrd</LI>
<LI>xfs-cmds</LI>
</UL>

These packages have also been provided for  
<A HREF="ftp://oss.sgi.com/projects/xfs/download/PreRelease-0.9/RH7.0-SGI-XFS_PR/RedHat/RPMS/">
download</A>.

After you have upgraded the necessary packages,
<A href="ftp://oss.sgi.com/projects/xfs/download/PreRelease-0.9/RH7.0-SGI-XFS_PR/RedHat/RPMS/"> 
download</A>
the appropriate kernel for your system architecture.<P>

The next step is to install the new kernel which provides XFS capability.
If you need more information on setting up a new kernel, please read the
<A href="http://www.redhat.com/support/docs/howto/kernel-upgrade/kernel-upgrade.html">
Upgrading the Linux Kernel on Red Hat Linux systems</A> document on Red Hat's
support site for general kernel upgrade information.<P>

Install the new RPMs using the command
<PRE><TT>       rpm -ivh <I>packagename</I>.rpm
</TT></PRE>

(Note that after the kernel RPM installs, modutils may complain
about renaming /etc/modules.conf to etc/conf.modules - you can safely
ignore this for now, if you wish)
<P>
The Prerelease-0.9 kernels have XFS support, SCSI support, and IDE support
all built as modules, so you will almost certainly need to create an
initial ramdisk.  To generate the initial ramdisk image, run the command:
<PRE><TT>       mkinitrd /boot/initrd-<I>kernelname</I>.img <I>kernelname</I>
</TT></PRE>

where <TT><I>kernelname</I></TT> refers to the new XFS kernel you have just
installed - for instance,

<PRE><TT>       mkinitrd /boot/initrd-2.4.0-SGI_XFS_PR.img 2.4.0-SGI_XFS_PR
</TT></PRE>

Finally, you will need to update your <TT>/etc/lilo.conf</TT> file to tell
it about your new kernel.  To do this, add the stanza:
<TT><PRE>       image=/boot/vmlinuz-<I>kernelname</I>
                label=xfs-beta
                initrd=/boot/initrd-<I>kernelname</I>.img
                read-only
                root=/dev/<I>rootpartition</I>
        
</PRE></TT>
where again, <TT><I>kernelname</I></TT> is the name of the new XFS kernel
you have just installed, and <TT><I>rootpartition</I></TT> is the name of
your root partition.  Also note that you may not require the <TT>initrd</TT>
line if your system does not need an initial ramdisk.  For example, if
you have installed an SMP kernel, and your root partition is on /dev/sda1,
you would add the stanza:
<TT><PRE>        image=/boot/vmlinuz-2.4.0-SGI_XFS_PR.smp
                label=xfs-pr
                initrd=/boot/initrd-2.4.0-SGI_XFS_PR.img
                read-only
                root=/dev/sda1

</PRE></TT>
to your <TT>/etc/lilo.conf</TT> file.<P>

Finally, run <TT>/sbin/lilo</TT> to finish up.  If it completes without
errors, locate your boot floppy (just in case), reboot the system, and type
<TT>xfs-pr</TT> at the LILO prompt when it comes up.<P>

If all this goes well, it's time to <A href="beta_filesystem_install.html">
make a new XFS filesystem!</A>
