<But does anyone have a good way to differentiate between 386SX and 386DX?

<Possibilities that come to mind include brute force speed comparison?
<Compare speed of moving data that is word v doubleword aligned?
<SX has 24 bit address bus, DX has 32 bits. Any easy way to test?
Isn't there a processor ID register in the 386 and up class?
