Flashing Firmware

How do I put the flash on 1 Floppy so I can flash the firmware from Dos? I must be missing something.

I use this cdrom to boot from:

ISO Boot

On the boot image is a driver call NTFSDOS, which gives you read-only access to NTFS partitions if you are using them. Just be sure to boot off of a different drive then the one you are trying to flash. I simply boot with this and flash from the hard drive. I have never had any problems and I am flashing in pure dos.
