---help---
Enable PCI and Cardbus support for the following chipset based cards:
ISL3880 - Prism GT 802.11 b/g
ISL3877 - Prism Indigo 802.11 a
ISL3890 - Prism Duette 802.11 a/b/g
For a complete list of supported cards visit <http://prism54.org>.
Here is the latest confirmed list of supported cards:
3com OfficeConnect 11g Cardbus Card aka 3CRWE154G72
Allnet ALL0271 PCI Card
Compex WL54G Cardbus Card
Corega CG-WLCB54GT Cardbus Card
D-Link Air Plus Xtreme G A1 Cardbus Card aka DWL-g650
I-O Data WN-G54/CB Cardbus Card
Kobishi XG-300 aka Z-Com Cardbus Card
Netgear WG511 Cardbus Card
Ovislink WL-5400PCI PCI Card
Peabird WLG-PCI PCI Card
Sitecom WL-100i Cardbus Card
Sitecom WL-110i PCI Card
SMC2802W - EZ Connect g 2.4GHz 54 Mbps Wireless PCI Card
SMC2835W - EZ Connect g 2.4GHz 54 Mbps Wireless Cardbus Card
Z-Com XG-900 PCI Card
Zyxel G-100 Cardbus Card
If you enable this you will need a firmware file as well.
You will need to copy this to /usr/lib/hotplug/firmware/isl3890.
You can get this non-GPL'd firmware file from the Prism54 project page:
<http://prism54.org>
You will also need the /etc/hotplug/firmware.agent script from
a current hotplug package.
Note: You need a motherboard with DMA support to use any of these cards
If you want to compile the driver as a module ( = code which can be
inserted in and removed from the running kernel whenever you want),
say M here and read <file:Documentation/modules.txt>. The module
will be called prism54.ko.
# yes, this works even when no drivers are selected
