C.1
Introduction
The DIO connector on the HPCIE-Q470 is interfaced to GPIO ports on the Super I/O
chipset. The digital inputs and digital outputs are generally control signals that control the
on/off circuit of external devices or TTL devices. Data can be read or written to the
selected address to enable the DIO functions.
NOTE:
For further information, please refer to the datasheet for the Super I/O
chipset.
The BIOS interrupt call
INT 15H
controls the digital I/O.
INT 15H:
