I used some DOC devices a few years ago. I think it maps code into a 
real mode region like a network boot ROM does and this aids the booting. 
I am not sure if it did the loading or emulated a floppy disk type 
device. It just worked. I was using FreeBSD and Linux.

I think the devices came with a FAT format and you could boot DOS if you 
loaded it onto the device. If you can get this to work I seem to 
remember meantion of a way to load RTEMS from a DOS command line prompt.
