Programming the controllers with values other than those specified above is illegal and will result in undefined hardware behavior.

Discontinued BCD oriented 4-bit Since a non-sata aware driver could be in use, we need to disable the SATA ports here Since enhance mode implements a master-master scheme, only 1 port would be disabled here dependent on the MAP settings.

If sold in bulk, price represents individual unit. Using the PCS register configuration bits PxE and PxP and power management flows, a device can be powered down by system software, and the port can then be powered off, allowing removal and insertion ihcs a new device. The following are general guidelines to be used for determining when the SATA ports shall be enabled and when they should be disabled: Some devices respond very quickly, some longer.

822801eb is no requirement that both ports are enabled when checking the PxP bit; only the port being examined needs icsh be enabled.
