Is it possible to swap a 386SX processor for the 286 processor on my
motherboard?

I seem to remember hearing that the pinouts are the same and that the
reason for making the 386SX was so that vendors could easily upgrade
there products (change the processor on the motherboard and sell it
as a 386SX instead of a 286).

I have a motherboard from JDR which is their 286-16Mhz model.  It
uses the Chips and Technologies Neat Chipset, and ATI BIOS.  Would I
need to change the BIOS also?

I would like to just make a change to a 16MHz 386SX if the processor
isn't too expensive, and if I can then run 386 multitasking
applications.

Thanks
