A while back I was having some trouble w/ my Inspiron 600m. I don't even remember what, but whatever it was got solved. While troubleshooting, however, I tried to update my BIOS, which is currently three versions and two years old. Downloaded the update from the Dell site. When I open it, I'm told I can't update because I have an "unsupported system." Apparently my computer believes its a Latitude D600. Ideas?
