- ---help---
- b43 is a driver for the Broadcom 43xx series wireless devices.
- Check "lspci" for something like
- "Broadcom Corporation BCM43XX 802.11 Wireless LAN Controller"
- to determine whether you own such a device.
- This driver supports the new BCM43xx IEEE 802.11G devices, but not
- the old IEEE 802.11B devices. Old devices are supported by
- the b43legacy driver.
- Note that this has nothing to do with the standard that your AccessPoint
- supports (A, B, G or a combination).
- IEEE 802.11G devices can talk to IEEE 802.11B AccessPoints.
- 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 V4 firmware, which must be installed separately using
- b43-fwcutter.
- This driver can be built as a module (recommended) that will be called "b43".
- If unsure, say M.

- ---help---
- Broadcom 43xx PCMCIA device support.
- Support for 16bit PCMCIA devices.
- Please note that most PC-CARD devices are _NOT_ 16bit PCMCIA
- devices, but 32bit CardBUS devices. CardBUS devices are supported
- out of the box by b43.
- With this config option you can drive b43 cards in
- CompactFlash formfactor in a PCMCIA adaptor.
- CF b43 cards can sometimes be found in handheld PCs.
- It's safe to select Y here, even if you don't have a B43 PCMCIA device.
- If unsure, say N.

- select B43_PIO
- ---help---
- Include both, Direct Memory Access (DMA) and Programmed I/O (PIO)
- data transfer modes.
- The actually used mode is selectable through the module
- parameter "pio". If the module parameter is pio=0, DMA is used.
- Otherwise PIO is used. DMA is default.
- If unsure, choose this option.
- config B43_DMA_MODE
- bool "DMA (Direct Memory Access) only"
- select B43_DMA
- ---help---
- Only include Direct Memory Access (DMA).
- This reduces the size of the driver module, by omitting the PIO code.
- config B43_PIO_MODE
- bool "PIO (Programmed I/O) only"
- select B43_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 43xx series support PIO.
- The 4306 (Apple Airport Extreme and others) supports PIO, while
- the 4318 is known to _not_ support PIO.
- Only use PIO, if DMA does not work for you.
