A driver for 802.11b wireless cards based on the "Hermes" or
Intersil HFA384x (Prism 2) MAC controller. This includes the vast
majority of the PCMCIA 802.11b cards (which are nearly all rebadges)
- except for the Cisco/Aironet cards. Cards supported include the
Apple Airport (not a PCMCIA card), WavelanIEEE/Orinoco,
Cabletron/EnteraSys Roamabout, ELSA AirLancer, MELCO Buffalo, Avaya,
IBM High Rate Wireless, Farralon Syyline, Samsung MagicLAN, Netgear
MA401, LinkSys WPC-11, D-Link DWL-650, 3Com AirConnect, Intel
IPW2011, and Symbol Spectrum24 High Rate amongst others.

This option includes the guts of the driver, but in order to
actually use a card you will also need to enable support for PCMCIA
Hermes cards, PLX9052 based PCI adaptors or the Apple Airport below.

You will also very likely also need the Wireless Tools in order to
configure your card and that /etc/pcmcia/wireless.opts works :
