Yep, that's the reason. There's nothing in the Newton OS that can help the Newton talks to this device. That's what drivers are all about. They're the intermediate between the hardware
and the OS. So, they can answer OS requests by talking directly to the device. In the case of an ATA card, when you insert it, the hardware triggers the OS to tell him a card has been
physically inserted. The OS then try to find a driver associated with it, or it might also try to request more info about the card from an existing driver. Since the existing drivers
can't talk to this card, they report that the card isn't recognized. Or if the OS is only looking for a specific driver associated with this type of card, then it reports very quickly
that the card isn't recognized, since no driver could be found.
