     ral -- Ralink Technology RT2500 IEEE 802.11 driver

     To	compile	support	for the
     ral driver	into your kernel, place	the following lines in your kernel
	 configuration file:

	   device ral
	   device wlan

	 Alternatively,	to load	the
     ral driver	at boot	time, place the	following line in loader.conf(5):


     The ral driver supports PCI/CardBus wireless adapters based on the	Ralink
     RT2500 chipset.

     The RT2500	chipset	consists of two	integrated chips, a RT2560 MAC/BBP and
     a radio transceiver (the model of which depends on	the card revision).

     The RT2522, RT2523, RT2524, RT2525, RT2525e and RT2526 radio transceivers
     operate in	the 2.4GHz band	(802.11b/g) whereas the	RT5222 is a dual-band
     radio transceiver that can	operate	in the 2.4GHz and 5.2GHz bands

     The transmit speed	is user-selectable or can be adapted automatically by
     the driver	depending on the received-signal strength.

     The following adapters should work:

     not happen.

     Ralink Technology,

     The ral driver first appeared in OpenBSD 3.7.

     PCI ral adapters seem to require a	PCI 2.2	compliant motherboard and will
     likely not	work with PCI 2.1 only motherboard.

     The ral driver was	written	by Damien Bergamini <>.
