Only the 8 most significant bits (D08 through D15) are routed to the 16-bit portion of the ISA slot.
If you have an ATA device that supports 8-bit transfers (CF cards, a handful of HDDs), there's no reason it can't be used in a 5160 XT or higher, using a regular 16-bit IDE controller and the XTIDE BIOS. (Not a 5150 for reasons I explain in my video on the topic)
To use normal HDDs that require 16-bit transfers, you need a "proper" XTIDE card that interleaves the high and low words on to the 8-bit data bus.
