4 floppy disk drives on a PC?

[Vintage Computer Festival]

I know we've discussed this before but the right Google search terms are
eluding me.

Is it possible to get 4 floppy drives onto a PC?  If so, how?  If I stick
two controllers in the PC and configure one with a different base address
and interrupt (assuming I can find a card that allows me to do this) will
DOS automatically recognize the second controller and extend the drive
letters C: and D: to the drives on that card?
