How to format a USB drive to FAT16?

How can I format a USB drive to FAT16?

I have a thumb drive partitioned to use Master Boot Record. The partitions are each 1GB in size. When I use Disk Utility to Erase one of those Partitions it offers "MS-DOS (FAT)" as a format choice, but when I Apply that the result is FAT32 format. There is only the one choice offered for MS-DOS style formatting -- all the other choices are MAC OS style formatting.

There doesn't appear to be any way to get Disk Utility to apply FAT16 format to that partition.

(I need FAT16 in order to use this USB drive for doing a firmware install on another device that doesn't understand FAT32 when doing firmware installs. Of course I can do FAT16 under Windows but I'm surprised there isn't a solution that doesn't require Windows.)

Not everyone is comfortable using Terminal commands. I'm posting these instructions in another venue for other Mac users who need to do firmware installs on this particular 3rd party device. I doubt most of them have ever tried to use Terminal before. Heck even Disk Utility is scary to some folks.

But again, thanks for the quick answer!
