+	---help---
+	  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.

+	  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).

+	---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.
