Re: [TCLUG:3624] A new subscriber...Video card
Well...
I took alook at the card and found the maufacture of most of the
componets. Attached is the info that I found, buy I am not sure how to
use it to my benifit. Also I remenber when installing Linux I recieved
some messages like *86Free something was corrupted and could not be
installed... maybe that has something to do with it.
I also I tried SuperProbe and my system didn't like that for some
reason.
thanks
