getting irda chip info ?

[Jan Bernatik <bernatik@xxxxxxxxxxx>]

Hi,

This is maybe not right place to ask
I have a laptop with builtin irda device, which I would like to make 
work, or try to write the driver for it (although I don't have 
sufficient programming practice yet ... I'm able to learn fast and work 
hard :) ) but I have a basic problem: I don't know what chip exactly is 
built in ... Docs of my notebook doesn't say anything usefull. It works 
in windows XP, so I trien to get some information from there, but the 
only useuful information I got was name of the chip is "nsc6001". This 
mean that manufacturer of the chip should be National Semiconductor 
company, but on their pages I found following info about irda chips they 
manufacture: http://www.national.com/pf/PC/PC87393.html
I tried to contact the manufacturer of the notebook, but they didn't 
respond in 3 days ... I also tried findchip utility from irda-utils 
package with this result ...

EFER seems to be probed at 0x03f0
chip ID is 0x0f : no known chip was detected.
Couldn't find Winbond superI/O chip.

I wonder if some of you know about other way of getting some information 
about the chip.
Thank you all, have a nice day
