[all variants] Can I change/update my BIOS from within Linux?

view story

http://ubuntuforums.org – Dear fellow Linux users, I have a computer that came preinstalled with Windows 7. I have since installed Linux (yipee!) on the hard drive. My Windows OS gives me a way to update the BIOS using the laptop manufacturer's program (some exe file). But I need to know if it's possible to change the BIOS from outside of Windows (either in Linux or some limbo-land). Thank you. (Hardware)
