This is an IDE device, so yes. The inserted card will be detected as an IDE hard disk. It has nothing to do with real PCMCIA controllers. For the latter, you need a card manager, socket services, filesystem drivers, and other stuff which is all complicated to use under DOS. And even then, not many cards will work (SRAM, Flash [no CF with adapter, only real flash cards], and some network/modem cards).

I have 2 ISA models that work in DOS, an I-O Data Carddock and a Ratoc REX-5051 with external enclosure:
