Bios update with a bootable cd?



So.. my diskdrive is broken. Can I update(flash) my bios with a bootable cd? I have this picture in my mind that the flashing program I use (dont remember what it was) searches the .bin ALLWAYS in A:\ and you cant change the dir :/


I realized that I posted this in to wrong section, soz. Plz answer ;)
as long as you're not installing any memory managers at boot-up i don't see why not. Your flash utility will look for the .bin file wherever you tell it to look, ususally in the same folder as the flash utility.
