 the Lucent Hermes, Intersil PRISM-II, Intersil PRISM-2.5, and Intersil
 Prism-3 chipsets.
 All chipsets provide a similar interface to the driver.
-Only the Intersil chipsets support access point operation.
-Functionality, such as WPA support, depends on the specific version
-of the firmware used.
+Only the Intersil chipsets support access point operation or WPA.
+Very old versions of firmware are not supported at all.
+Older versions of the firmware that are supported may severely limit

+Only relatively recent versions of Intersil firmware supports WPA.
+See CAVEATS for details.

 that support a DMA interface.
