I haven't done a BIOS update on a Dell in ages. On any pre-built in fact. It's pretty easy on modern boards that come with utility disks that include a Win-based app to search it out and update it for you. I don't suppose Dell offers anything like that?
Can you link me to the page that includes BIOS updates for your system?

That is a .EXE file that has to be run in Windows. So it appears to be a self-installing BIOS flash. Not like the old days. Get the card, try it with the existing BIOS. If it isn't recognized (I think it will be), take it out and put the old card back in, and do the BIOS update.
