Need help with updating systems BIOS.

Hello my computer savy friends. I am in need of your help. Apparently, I have an out dated BIOS, or so Vista tells me. I know, Vista is terrible, I have installed Windows 7 on my laptop just so I could avoid all the problems, however I ran into even more problems. The OS that came with the laptop has the software and drivers to run all the gadgets that came with the laptop. (webcam, microphone, chipset drives etc.) Windows 7 has none of these drivers. So I have to bite the bullet, and deal with Vista. So thank goodness I have PC Wizard, because I’m going to speak in a more understandable language for us geeks, or intelligent gentlemen. Here is my laptops information. Thank you in advance for taking the time to read it. :)
