IDE Connector
The IDE interface connector is used for connection with IDE devices such as
hard disk drives and CD-ROMs. There are two EIDE interfaces supporting
up to 4 IDE devices on the cPCI-6830. The IDE interface signals are routed
to a 44-pin header.
The default mode is "compatibility mode," meaning that the interface uses
the PC-AT legacy addresses of F0h-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.
