Flashing my BIOS

Im running and A8N SLI-Deluxe with an AMD 4000+ Clawhammer, GeForce 7800 GT, and 1 stick of 512 PC2100 (I have a 1gig stick of 3200, but im going to wait to switch them out till I get this done)

I need to flash my Bios, so that I may install the latest version...I will be doing this without an OS....I have (1)x DOS Boot Floppy and (1)x Bios Update Floppy

My question is......what do I do? lol. How do I go about installing the new version....I also have a CD with the NVIDIA Chipset Update, which I should be able to boot from with my DVD ROM. Can someone help me out?

 

Okay so im told, to make sure everything is hooked up and ready to go. Insert disk, and boot up. Go into the Bios, and in there, there should be an Update feater, EZ-Update or something. It should read the app off the disk, and its all oldies but goldies from there on out. Is this correct? Or is there someone who thinks I should do it a different way. FOr those confused, Im trying to flash my bios so I can instal the lates BIOS version from a floppy, so my motherboard will detect my IDE Drives.
