PIDE_IOR*
Primary Drive I/O Read – Primary strobe signal for read functions.
Negative edge enables data from a register or data port of the drive onto the
host data bus. Positive edge latches data at the host.

PIDE_DRQ
Primary DMA Request – Used for DMA transfers between host and drive
(direction of transfer controlled by IOR* and IOW*). Also used in an
asynchronous mode with ACK*. Drive asserts an IRQ when ready to
transfer or receive data.
