Except for the hot-pluggable part, you are correct. The PCI sub-class code distinguishes emulation from native not parallel from serial. However, there is no assumptions about hot-pluggable made in either. The purpose of this is to prevent the loading of existing PATA drivers on SATA controllers that do not emulate PATA.

Nothing about how to distinguish a parallel ata device from a serial ata device? Pat LaVarre
