wiki:HardwareInfo/WirelessFirmwares

Version 25 (modified by colin, 10 years ago) (diff)

Firmware requirements for broadcom43xx added.

This page tries to list all the legal and technical implications of distributing the different WiFi firmwares for use on Haiku.
While a nice source of info, it is not intended as a user install guide but for Haiku developers and contributors to bring WiFi on Haiku while fully complying to the various vendor licenses and copyrights.

General

Should we ask vendors for agreements when necessary? (cf. Old OSNews Article) todo: find the contact points

Broadcom

Recommended firmware versions

The FreeBSD 8 driver only supports firmwares of version 3 (see link below). There is only one version 3 firmware available.

b43xx

  • http://linuxwireless.org/en/users/Drivers/b43#device_firmware
  • from the above link, "Please note that the firmware from the binary drivers is Copyrighted by Broadcom Corporation and must not be redistributed." and "Because the proprietary driver containing the firmware cannot be included in the distribution, you will need a working connection to the Internet."
  • A required tool, 'b43-fwcutter' is GNU GPL V2. HaikuPorts has ported b43-fwcutter
  • One of the suggested driver downloads, broadcom-wl-4.80.53.0.tar.bz2 contains a file 'WHERE_FROM' with the contents "From the Linksys WRT350N v1.03.2 GPL release"
  • At least some distributions explicitly request acknowledgment from the end user.

-> Distribution method: post install unmodified download + post download processing + license warning ?
