I have one.

The board uses a single PCI interrupt when in "native" mode,
and a pair of interrupts when in "compatibility" mode (IRQ14/15),
as do *all* compliant PCI IDE controllers.

Note the confusion may simply be that a *single* "IDE controller"
these days always supports *two* hwif's (interfaces).

The Promise RAID card is identical to the Promise Ultra33 IDE card,
except for a different on-board BIOS.
