If you have a friend who can lend you a usb floppy drive, that may work. But bad bios flashes are not good. Why did you flash it anyway just out of curiosity. Generally you don't want to do a bios flash unless you have to. I recently flashed the bios on my homebuilt desktop because of some newer processors it will support, however, I was able to back up the stock bios and had the option for reflashing in case something went wrong. Which I actually did have to go back to.
