NOTES:
1. Only if IDE Standard I/O space is enabled for Primary Channel and the IDE Controller is in legacy mode.
2. Only if IDE Standard I/O space is enabled for Secondary Channel and the IDE Controller is in legacy mode.
3. If POS_DEC_EN bit is enabled, reads from F0h will not be decoded by the ICH5. If POS_DEC_EN is not
