Freebsd install usb cdrom

I want to create a universal carrier. Does anyone have any solutions to get FreeBSD installing via the DVD on this usb dvd drive. This destroys all data on the flash drive.
Just download and use the memorystick image with the steps below. - Use dd or gpart software - destroy your USB Flash. Ignore the Geom not found warning.
We want FreeBSD to boot into a serial console for our install. I have an external USB hard drive. Iso files to a bootable USB stick drive so it can be used to install from. Create a bootable BSD slice on the USB flash drive, using the entire disk. That will be seen from the other OS. USB flash drive must have a slice. Sh script to convert the ISO into an appropriate disk image.
