Per DPIOO1, does this go to false for the first DRQ block, or did I
misunderstand? Currently my understanding:

- device->host
        DPIOI1
        Interrupt bit shall be set.
- host->device:
        DPIOO1:
        0 for first block, 1 otherwise
- ATAPI:
        0 for packet itself
        1 for all data otherwise.

Yes?
