I/O Mapping
The I/O map for the IDE interface varies depending on the mode of operation. The default
mode is "compatibility mode," meaning that the interface uses the PC-AT legacy addresses of
1F0h-1F7h, with 3F6h and interrupt IRQ14 for the primary channel. The secondary channel
uses I/O addresses 170h-177h, 376h and interrupt IRQ15. No memory addresses are used.
CompactFlash Carrier
Intel provides an optional IDE CompactFlash Carrier (ZT 96080) that can be mounted in the
hard drive location on the ZT 5504. This carrier accommodates multiple types of CompactFlash
cards, which appear to the system as a hard drive, and are automatically supported by most
operating systems. For more information about the ZT 96080 CompactFlash Carrier, see the
Intel NetStructure building blocks page at:

Device Drivers
The IDE interface works with all applications by default. To fully utilize the IDE interface,
additional software drivers may be installed. Contact the vendor of your intended operating
system to receive the latest drivers for the Intel PIIX4E (82371EB) EIDE interface.
Note: If problems are encountered installing the QNX operating system, ver. 4.24, on a CompactFlash
card, restart the install program and specify regular IDE drivers (Fsys.ide) instead of the default EIDE
drivers (Fsys.eide).
