  You can have a mix of MFM, RLL, and ESDI with UNIX. With DOS you can
mix if the BIOS can be readdressed and the controller supports being put
at a secondary address. I don't know what magic you need to make the o/s
use the 2nd controller in DOS, in theory it should create the device
control blocks during init.
