Apparently, somewhere in their OWN documents, they say to not use this mode, it doesn't work! Others have commented the 9815 is the same.
The whole scheme of the EPP mode is the chip does the hardware handshaking, and that includes making the PC CPU go into a wait state until the transfer is done. I don't recall the exact nature of the problem, but the chip simply doesn't perform this part of the operation reliably. Something like 20% of the transfers don't handshake correctly. So, if the 9815 has the same sort of bug as the 9805, then it CAN'T be made to work in EPP mode.
