-          Find out whether you have a PCI motherboard. PCI is the name of a
-          bus system, i.e. the way the CPU talks to the other stuff inside
-          your box. Other bus systems are ISA, EISA, MicroChannel (MCA) or
-          VESA. If you have PCI, say Y, otherwise N.
-
-          The PCI-HOWTO, available from
-          <http://www.tldp.org/docs.html#howto>, contains valuable
-          information about which PCI hardware does work under Linux and which
-          doesn't.
+          Real IA-64 machines all have PCI/PCI-X/PCI Express busses.  Say Y
+          here unless you are using a simulator without PCI support.
