ide-disk

Description

Instances of the ide-disk class are generic IDE disks with several of tunable parameters. PIO is supported up to mode 4, and Ultra DMA up to level 2.

Interfaces Implemented

conf_object, log_object, ide_device

Notifiers

cell-change: Notifier that is triggered after the object's cell was changed.
object-delete: Notifier that is triggered just before Simics object is deleted.
queue-change: Notifier that is triggered after the object's clock was changed. New clock can be obtained with the SIM_object_clock function.
