-`options COM_BIDIR'
-     This option enables bi-directional support in the `sio' serial
-     driver.  This option is slated for removal, at which time
-     bi-directional support will always be enabled.  See the
-     `comcontrol' manual page for more information.
+`options ALLOW_CONFLICT_IOADDR'
+     Allow devices on the ISA bus to share conflicting IO address
+     spaces.  This is generally an error, though things like PS/2 mouse
+     drivers which are implemented seperately from the keyboard driver
+     will require this option to be set.  Note that this is almost
+     always sub-optimal, and the current PS/2 mouse driver will, in
+     fact, frequently fight with the keyboard if you try to use them
+     concurrently.  Needing this option enabled is a sure sign that you
+     need to consider a different design for your driver.
+
+`options ALLOW_CONFLICT_IRQ'
+     Allow devices on the ISA bus to share conflicting IRQ's.  This is
+     often necessary for multiport serial cards which have several
+     devices at the same IRQ.  Enable this only with caution!
