Drive 1 DMA Timing Enable (DTE1) — R/W.
0 = Disable.
1 = Enable the fast timing mode for DMA transfers only for this drive. PIO transfers to the IDE data
Drive 1 Prefetch/Posting Enable (PPE1) — R/W.
0 = Disable.
1 = Enable Prefetch and posting to the IDE data port for this drive.
Drive 1 IORDY Sample Point Enable (IE1) — R/W.
0 = Disable IORDY sampling for this drive.
1 = Enable IORDY sampling for this drive.
Drive 1 Fast Timing Bank (TIME1) — R/W.
0 = Accesses to the data port will use compatible timings for this drive.
1 = When this bit = 1 and bit 14 = 0, accesses to the data port will use bits 13:12 for the IORDY
