Lines: 17 >After all, IDE >is basically a "transparent" extension of the ISA bus... IDE means "integrated drive electronics". It simply means that the controller is on the drive. IDE does not imply anything about the actual electrical interface. If an IDE drive is designed to be connected to an ISA bus, then of course it is a transparent extension of the bus, and looks like a standard AT drive. If an IDE drive is custom-engineered for some manufacturer, then there is no guarantee as to what it looks like electrically. If an IDE drive has a SCSI interface, then it has a SCSI interface and not an AT interface. Etc. Interpret "IDE" as meaning "when you buy the drive, you automatically get the controller with it". -- Rahul Dhesi UUCP: oliveb!cirrusl!dhesi
