4 floppy disk drives on a PC?

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? -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
