+          b43legacy is a driver for 802.11b devices from Broadcom (BCM4301 and
+          BCM4303) and early model 802.11g chips (BCM4306 Ver. 2) used in the
+          Linksys WPC54G V1 PCMCIA devices.
+
+          Newer 802.11g and 802.11a devices need b43.
+
+          It is safe to include both b43 and b43legacy as the underlying glue
+          layer will automatically load the correct version for your device.
+
+          This driver uses V3 firmware, which must be installed separately using
+          b43-fwcutter.
+
+          This driver can be built as a module (recommended) that will be
+          called "b43legacy". If unsure, say M.

+          Say Y, because this information will help you get the driver running.
+          This option generates a minimum of log output.

+        ---help---
+          Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
+          data transfer modes. The mode actually used is selectable through
+          the module parameter "pio". With pio=0 as a module parameter, the
+          default DMA is used, otherwise PIO is used.
+
+          If unsure, choose this option.
+
+config B43LEGACY_DMA_MODE
+        bool "DMA (Direct Memory Access) only"
+        select B43LEGACY_DMA
+        ---help---
+          Only include Direct Memory Access (DMA).
+          This reduces the size of the driver module, by omitting the PIO code.
+
+config B43LEGACY_PIO_MODE
+        bool "PIO (Programmed I/O) only"
+        select B43LEGACY_PIO
+        ---help---
+          Only include Programmed I/O (PIO).
+          This reduces the size of the driver module, by omitting the DMA code.
+          Please note that PIO transfers are slow (compared to DMA).
+
+          Also note that not all devices of the b43legacy series support PIO.
+
+          You should use PIO only if DMA does not work for you.
