The info from linksys on that card re: linux is at
http://www.linksys.com/support/solution/nos/linux_lne100tx.htm

To get the driver disks, and for a little more info (a more telling page)
http://www.linksys.com/dlc/howtotelllne100tx.htm

which describes how to tell which version of the card you have, which also can give an
idea of which driver might work for that card. The LNE100TX card is an example of one
where the manufacturer modified the hardware for the card, but kept the same product
name and number... (if you order one of these cards, there is no way to tell without
looking at the chips on it which one you are getting. I have had it where someone I
know had ordered 20 from their supplier, and got a mix of the different cards. the
boxes were exactly the same.....
