The Intel 80386dx or iapx386dx or ... is the version of the standard (32 bit data path) 386 which contains the fix for the bug in handling DMA + 387 + Interrupt situations. I believe it also contains a few other fixes. It is later than the double sigma revision. I believe all the 33MHz chips and maybe all the 25MHz chips are dx's -- I haven't seen any that weren't.
