It's time for a monthly frequently asked questions posting!!!! Where were
you yesterday when this question was asked, and answered!!!!
There is no difference between a 386DX and a 386SX except speed. 386SXs are
only available in 16mhz parts right now. A 16mhz 386DX will be marginally
faster than a 386SX because of the difference in the bus architecture.
An SX must go to the memory bus twice to get a 32bit word, while the DX
need only go once.
Chewey, get us outta here!
