+	 Linux on i386 architecture normally supports just 896Mb without
+	 enabling HIGHMEM support. This option will enable you to support 1Gb
+	 of ram without needing to enable HIGHMEM support. The advantage of
+	 this is that you don't need the extra overhead of high memory support
+	 to utilise the last 128Mb of ram. However this may break drivers such
+	 as vmware.
+
+	 If unsure say "no"
