+ 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.

+ 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

+config B43LEGACY_DMA_MODE

+ 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.
