+		<title>Important — Systems with Intel BIOS-RAID sets</title>
+		<para>
+			From Fedora 12 onwards, Fedora uses <application>mdraid</application> instead of <application>dmraid</application> for installation onto Intel BIOS-RAID sets. These sets are detected automatically, and devices with Intel ISW metadata are recognized as mdraid instead of dmraid after this change. Note that the device node names of any such devices will change. Therefore, special precautions are necessary when you upgrade systems with Intel BIOS-RAID sets.
+		</para>
+		<para>
+			If the system has local modifications to <filename>/etc/fstab</filename>, <filename>/etc/crypttab</filename>, or to other configuration files which refer to devices by their device node names, the system will not recognize these devices when you upgrade to Fedora &PRODVER;. Before upgrading, you must therefore edit these files to replace device node paths with device UUIDs instead. You can find the UUIDs of devices with the <command>blkid</command> command. 
+		</para>
+		<para>
+			Default configurations of Fedora 11 already refer to Intel BIOS-RAID sets by UUID and not by device node names. Therefore, you can upgrade default installations without encountering this issue.
+		</para>
+		<para>
+			Note also that the Fedora Live CD continues to use <application>dmraid</application> to access Intel BIOS RAID sets. Therefore, any installations performed from the Live CD also continue to use <application>dmraid</application>.
