I found quite interesting article : http://www.nodomainname.co.uk/ma401/ma401.htm
In the end of this article it's written:
---------------------------------------------------------------------------------
Although as yet untested, reference to the following Intersil document 
http://www.intersil.com/data/fn/fn4/fn4856/fn4856.pdf 
shows that CR31 controls the transmit power which is by default at 0xF0. Setting this 
to 0x80 (these values are in hex, just 
use 80 in the software!) should set the power to 100mW instead of the default 30mW.
The tool to do this is at http://www.intersil.com/design/prism/software-
o/PrismTestUtil322.exe.
---------------------------------------------------------------------------------
Unfortunately all these links are dead:(

Thanks to google, I found Jouni Malinen post (http://hostap.epitest.fi/hostap/2002-
03/0300.html):
---------------------------------------------------------------------------------
'writemif' can be used with following command: 'iwpriv wlan0 writemif <CR*2> <value 
to be written>' (e.g., 'iwpriv wlan0 
writemif 26 17' sets bits 4 (SleepIQ) and 0 (Enable test mode commands) of CR13.
---------------------------------------------------------------------------------

Does it mean that 'iwpriv wlanX writemif' configures registers, and it's no need of this 
windows program? However it's need of fn4856.pdf document, so have somebody 
downloaded this doc earlear, maybe you could share it with me?

Is it possible to increase power of Intersil Prism2x card using this way?
