Actually, 486 DX had built-in FPU as well. It was missing from 486SX (486SX + optional 487 FPU = 486DX).
For 386(DX|SX) there were 387(DX|SX) (386SX used 16-bit bus).
Many 32-bit motherboards had a socket for Weitek (3167 for 386DX or 4167 for 486). I think I remember a board with 386DX and 287 socket as well.
486DX2 meant the external clock was half the internal. -- Krzysztof Halasa - To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
