Could someone please explain or direct me to an article that explains in some detail the difference(s) between a full 80386 microprocessor (80386DX) and the 80386SX? Are they both 32-bit processors? I've heard that the main difference is that the SX "talks" to the outside world (memory, disk, etc) at 16-bits while the DX uses 32 bits. Is this true and is this the only difference? Are there any limitations on the 386SX running 386-specific software? _Any_ info that can be provided (technical or not) would be appreciated. Thanks in advance.
