As most of you know, SATA HDDs can be run in IDE emulation mode. Will the same thing hold true of SATA optical drives? Here's a possible situation; a computer has been configured with no SATA drivers. The HDDs are set to "run as IDE". Suppose someone wanted to add a Blu-Ray drive, all of which are SATA. Would this require a reinstall of the OS with SATA drivers, or would the BIOS compensate and enable the drive to function correctly as an IDE unit?
