"Onboard IDE Operate Mode" [Enhanced]
"IDE Port Settings" [S-ATA]

When operating in Enhanced mode (where all six possible
drives are mapped as PCI bus devices in hardware), the
only valid setting is [S-ATA]. The other settings cause
the hardware to slow down.

If you use the [Compatible] setting, then all
three possible port settings are valid choices,
as in that case, the port settings are selecting
four of six drives for use.
