[ubuntu] How to update my BIOS?

view story

http://ubuntuforums.org – Hello everyone. I need to upgrade my BIOS to a new version, problem is: On Windows there's a .exe where I used to download and then execute. On Linux there's no executable, so I decided to run a flash-bios. The download is a .zip file which contains a file inside it. What should I burn onto the DVD? The .zip, or the file inside it? I'll flash my bios over a "bootable" DVD containing the archive but I never did it so I need your help. PS: I have only one DVD left tonight so please confirm only if you're absolutely sure! :p Attached Images (Hardware)
