yes.

yes, you are right, the interrupt number defined in the gen5200 BSP is
only suitable for the MPC5200 microcontroller. I am sorry, but I am not
an expert for the i286 architecture. I can only give you a guess:
interrupt number 14 MIGHT be the right one to use for the primary IDE
device.

wkr,
Thomas.
